Community informatics (CI) is an interdisciplinary field that is concerned with using information and communication technology (ICT) to empower members of communities and support their social, cultural, and economic development. Community informatics may contribute to enhancing democracy, supporting the development of social capital, and building well connected communities; moreover, it is probable that such similar actions may let people experience new positive social change. In community informatics, there are several considerations which are the social context, shared values, distinct processes that are taken by members in a community, and social and technical systems. It is formally located as an academic discipline within a variety of academic faculties including information science, information systems, computer science, planning, development studies, and library science among others and draws on insights on community development from a range of backgrounds and disciplines. It is an interdisciplinary approach interested in using ICTs for different forms of community action, as distinct from pure academic study about ICT effects.

Background

Most humans live in communities. In some urban areas, community and neighborhood are conflated but this may be a limited definition. Communities are defined as people coming together in pursuit of common aims or shared practices through any means, including physical, electronic, and social networks. They proliferate even while the ability to define them is amorphous.

Cultures ensure their growth and survival by continuing the norms and mores that are the bases of their way of life. Communities can use the infrastructure of ICTs as a method of continuing cultures within the context of the Internet and the World Wide Web. Once a cultural identity is defined within the context of these technologies, it can be replicated and disseminated through various means, including the sharing of information through websites, applications, databases, and file sharing. In this manner, a group that defines its cultural identity within the construct of technology infrastructure is empowered to hold valuable exchanges within the spheres of economics, political power, high and popular culture, education, and entertainment.

Since the inception of the Internet and the World Wide Web, we have seen the exponential growth of enterprises ranging from electronic commerce, social networking, entertainment and education, as well as a myriad of other contrivances and file exchanges that allow for an ongoing cultural enrichment through technology. However, there has been a general lag as to which populations can benefit through these services through impediments such as geographic location, a lack of funds, gaps in technology and the expertise and skills that are required to operate these systems.

To date there has been very considerable investment in supporting the electronic development of business communities, one-to-many social tools (for example, corporate intranets, or purpose-built exchange and social networking services such as eBay, or Myspace), or in developing applications for individual use. There is far less understanding, or investment in human-technical networks and processes that are intended to deliberately result in social change or community change, particularly in communities for whom electronic communication is secondary to having an adequate income or social survival.

The communal dimension (and focus of Community Informatics) results in a strong interest in studying and developing strategies for how ICTs can enable and empower those living in physical communities. This is particularly the case in those communities where ICT access is done communally, through Telecentres, information kiosks, community multimedia centres, and other technologies. This latter set of approaches has become of very considerable interest as Information and Communications Technology for Development (ICT4D) has emerged as significant element in strategic (and funding) approaches to social and economic development in Less Developed Countries. ICT4D initiatives have been undertaken by public, NGO and private sector agencies concerned with development such as the United Nations Development Program, the World Bank, the Swiss Agency for Development and Cooperation (SDC), the MS Swaminathan Research Foundation; have emerged as a key element in the poverty alleviation component of the UN's Millennium Development Goals; and as important directions for private sector investment both from a market perspective (cf. the "Bottom of the Pyramid") and from companies concerned with finding a delivery channel for goods and services into rural and low income communities.

While the progress of ICT4D has been remarkably fast in general as communities become more information-based, digital divide appears to be a great challenge to its proponents. Although access to information technology in North America and Europe is high, it is the complete opposite in other regions of the world, particularly in Africa and in some parts of Asia. For instance, in the ASEAN region alone, there are countries who are leaders in digital technology such as Singapore, Malaysia, and Thailand while on the other side of the pole are countries who have very poor access to and development in digital technology including Cambodia, Lao PDR, Myanmar, and Vietnam. The effectiveness of ICT as a tool for development is highly contingent on the capacity of all countries to accommodate and maintain information and communications technology.

There is thus growing interest in Community Informatics as an approach to understanding of how different ICTs can enable and empower marginalized communities to achieve their collective goals.

Understanding communities

It is crucial to know how communities are formed and evolved and how the participation to a community occurs and differs while formation process. Understanding the nature of communities and the participation process will surely ensure designing and implementing a successful ICT solution that benefits members of community while communicating with each other or performing certain tasks. The following points include a brief description of the nature of each potential community formation.

Community as a place

A group of people may form a community according to the place in which they live, enjoy staying, and work. They usually participate in communities within these three places since they gather together on consistent basis so that it is highly expected that such community is formed. Beside the home and the work gathering, people usually like to spend their time at informal places called third places in where they meet their new or old friends or have a chance to meet new people.

Community as a socio-spatial entity

A group of people may form a community as they have frequent direct interactions or live in close proximity to each other. The members of such community may have strong bond and focused common goals which give them a higher status over other communities. Moreover, as the number of the members increases, the community may become reputable and has a higher status over other communities.

A group of people may form a community as they have common shared identity. People may form such community to support and advocate common shared values, morals or norms in which they believe. Such a community may have a set of symbols and be associated with a status over other communities. The inclusion and the exclusion to such community depend on whether or not a member share the same identity with others in the community. For instance, people who descend from one origin may form a community in which only people from that origin can join the community even though they do not know each other in advance.

Community of interests

A group of people may form a community as they have similar affinity for a particular activity, experience, or subject. The geographical location is not necessary while forming such community, and the inclusion and the exclusion to such community depends on whether a new member has that affinity or not.

Communities linked to life stage

A group of people may form a community if they share a similar experience in a distinct life stage. The experience could be related to the members themselves or to their relatives, such as their children. For instance, parents of elementary school children may form a community in which they care about their children while in school. As it is mentioned in the previous type of community formation, the members of such community have a common interest which is caring about their children while in school. This type of community may persist over time, but the inclusion and the exclusion to it may happen consistently as people are no longer in that distinct life stage.

Communities of practice

A group of people who share a similar profession may form a community in which they work to attain their goals and advance in their profession. Three important concepts are considered while forming community of practice which are mutual engagement, joint enterprise, and shared repertoire. In a community of practice, the members have to be mutually engaged with each other by establishing collaborative relationships that will allow them to willingly work on certain joint activities. In the second concept which is joint enterprise, the members of a community of practice are supposed to discuss and agree upon the work responsibilities so that they can work in harmony, and each member knows his responsibility and his expected contributions to the community. In addition to these two concepts, the members of the community of practice have a shared repertoire of procedures or ways to perform certain tasks. They usually agree upon these procedures and practices that they establish and develop over time.

Conceptual approaches

As an academic discipline, CI can be seen as a field of practice in applied information and communications technology. Community informatics is a technique for looking at economic and social development within the construct of technology—online health communities, social networking websites, cultural awareness and enhancement through online connections and networks, electronic commerce, information exchanges, as well as a myriad of other aspects that contributes to creating a personal and group identity. The term was brought to prominence by Michael Gurstein. Michael Gurstein says that community informatics is a technology strategy or discipline that connects at the community level economic and social development with the emergence of community and civic networks, electronic commerce, online participation, self-help, virtual health communities, "Tele-centres", as well as other types of online institutions and corporations. He brought out the first representative collection of academic papers, although others, such as Brian Loader and his colleagues at the University of Teesside used the term in the mid-1990s.

CI brings together the practices of community development and organization, and insights from fields such as sociology, planning, computer science, critical theory, women's studies, library and information sciences, management information systems, and management studies. Its outcomes—community networks and community-based ICT-enabled service applications—are of increasing interest to grassroots organizations, NGOs and civil society, governments, the private sector, and multilateral agencies among others. Self-organized community initiatives of all varieties, from different countries, are concerned with ways to harness ICT for social capital, poverty alleviation and for the empowerment of the "local" in relation to its larger economic, political and social environments. Some claim it is potentially a form of 'radical practice'.

Community informatics may in fact, not gel as a single field within the academy, but remain a convenient locale for interdisciplinary activity, drawing upon many fields of social practice and endeavour, as well as knowledge of community applications of technology. However, one can begin to see the emergence of a postmodern "trans-discipline" presenting a challenge to existing disciplinary "stove-pipes" from the perspectives of the rapidly evolving fields of technology practice, technology change, public policy and commercial interest. Whether or not such a "trans-discipline" can maintain its momentum remains to be seen given the incertitude about the boundaries of such disciplines as community development.

Furthermore, there is a continuing disconnect between those coming from an Information Science perspective for whom social theories, including general theories of organisation are unfamiliar or seemingly irrelevant to solving complex 'technical' problems, and those whose focus is upon the theoretical and practical issues around working with communities for democratic and social change

Given that many of those most actively involved in early efforts were academics, it is only inevitable that a process of "sense-making" with respect to these efforts would follow from "tool-making" efforts. These academics, and some community activists connected globally through the medium.

A first formal meeting of researchers with an academic interest in these initiatives was held in conjunction with the 1999 Global Community Networking Conference in Buenos Aires, Argentina. This meeting began the process of linking community-based ICT initiatives in developed countries with initiatives undertaken in developing countries, which were often part of larger economic and social development programmes funded by agencies such as the UN Development Programme, World Bank, or the International Development Research Centre. Academics and researchers interested in ICT efforts in developed countries began to see common and overlapping interests with those interested in similar work in less developed countries. For example, the issue of sustainability as a technical, cultural, and economic problem for community informatics has resulted in a special issue of the Journal of Community Informatics as well as the subject of ongoing conferences in Prato, Italy and other conferences in South Africa.

In Canada, the beginnings of CI can be recognized from various trials in community networking in the 1970s (Clement 1981). An essential development occurred in the 1990s, due to the change of cost of computers and modems. Moreover, examples of using computer networking to initiate and enhance social activities was acknowledged by women's groups (Balka 1992) and by the labor movement (Mazepa 1997).

Social informatics beyond an immediate concern for a community

Social informatics refers to the body of research and study that examines social aspects of computerization—including the roles of information technology in social and organizational change, the uses of information technologies in social contexts, and the ways that the social organization of information technologies is influenced by social forces and social practices. Historically, social informatics research has been strong in the Scandinavian countries, the UK and Northern Europe. In Europe some researchers have pointed out that in order to create awareness of the importance of social issues of computing, one has to focus on didactics of social informatics. Within North America, the field is represented largely through independent research efforts at a number of diverse institutions. Social informatics research diverges from earlier, deterministic (both social and technological) models for measuring the social impacts of technology. Such technological deterministic models characterized information technologies as tools to be installed and used with a pre-determined set of impacts on society dictated by the technology's stated capabilities. Similarly, the socially deterministic theory represented by some proponents of the social construction of technology (SCOT) or social shaping of technology theory see technology as the product of human social forces.

Criticisms

There is a tension between the practice and research ends of the field. To some extent this reflects the gap, familiar from other disciplines such as community development, community organizing and community based research. In addition, the difficulty that Information Systems has in recognising the qualitative dimension of technology research means that the kind of approach taken by supporters of community informatics is difficult to justify to a positive field oriented towards solutions of technical, rather than social problems. This is a difficulty also seen in the relationship between strict technology research and management research. Problems in conceptualising and evaluating complex social interventions relying on a technical base are familiar from community health and community education. There are long-standing debates about the desire for accountable – especially quantifiable and outcome-focused social development, typically practised by government or supported by foundations, and the more participatory, qualitatively rich, process-driven priorities of grass-roots community activists, familiar from theorists such as Paulo Freire, or Deweyan pragmatism.

Some of the theoretical and practical tensions are also familiar from such disciplines as program evaluation and social policy, and perhaps paradoxically, Management Information Systems, where there is continual debate over the relative virtue and values of different forms of research and action, spread around different understandings of the virtues or otherwise of allegedly "scientific" or "value-free" activity (frequently associated with "responsible" and deterministic public policy philosophies), and contrasted with more interpretive and process driven viewpoints in bottom-up or practice driven activity. Community informatics would in fact probably benefit from closer knowledge of, and relationship to, theorists, practitioners, and evaluators of rigorous qualitative research and practice.

A further concern is the potential for practice to be "hijacked" by policy or academic agendas, rather than being driven by community goals, both in developed and developing countries. The ethics of technology intervention in indigenous or other communities has not been sufficiently explored, even though ICTs are increasingly looked upon as an important tool for social and economic development in such communities. Moreover, neither explicit theoretical positions nor ideological positioning has yet emerged. Many projects appear to have developed with no particular disciplinary affiliation, arising more directly from policy or practice imperatives to 'do something' with technology as funding opportunities arise or as those at the grassroots (or working with the grassroots) identify ICT as possible resources to respond to local issues, problems or opportunities. The papers and documented outcomes (as questions or issues for further research or elaboration) on the wiki of the October 2006 Prato conference demonstrate that many of the social, rather than technical issues are key questions of concern to any practitioner in community settings: how to bring about change; the nature of authentic or manufactured community; ethical frameworks; or the politics of community research.

A different strain of critique has emerged from gender studies. Some theorists have argued that feminist contributions to the field have yet to be fully acknowledged and Community Informatics as a research area has yet to welcome feminist interventions. This exists despite the presence of several gender-oriented studies and leadership roles played by women in community informatics initiatives.

Research and practice interests

Research and practice ranges from concerns with purely virtual communities; to situations in which virtual or online communication are used to enhance existing communities in urban, rural, or remote geographic locations in developed or developing countries; to applications of ICTs for the range of areas of interest for communities including social and economic development, environmental management, media and "content" production, public management and e-governance among others. A central concern, although one not always realized in practice is with "enabling" or "empowering" communities with ICT that is, ensuring that the technology is available for the community. This further implies an approach to development which is rather more "bottom up" than "top down".

Areas of concern range from small-scale projects in particular communities or organizations which might involve only a handful of people, such as telecentres; an on online community of disabled people; civic networks and to large national, government sponsored networking projects in countries such as Australia and Canada or local community projects such as working with Maori families in New Zealand. The Gates Foundation has been active in supporting public libraries in countries such as Chile. An area of rapidly developing interest is in the use of ICT as a means to enhance citizen engagement as an "e-Governance" counterpart (or counterweight) to transaction oriented initiatives.

A key conceptual element and framing concept for Community Informatics is that of "effective use" introduced initially by Michael Gurstein in a critique of a research pre-occupation with the Digital Divide as ICT "access". CI is concerned with how ICTs are used in practice and not simply facilitating "access" to them and the notion of "effective use" is a bridge between CI research (research and analysis of the constituent elements of effective use), CI policy (developing enabling structures and programmes supportive of "effective use") and practice (implementing applications and services in support of local communities).

Another way to understand CI is Clement and Shade's "access rainbow" (Clement and Shade 2000). Clement and Shade have contended that accomplishing insignificant specialized connectedness to the Internet is no assurance that an individual or group will prevail with regards to appropriating new ICTs in ways that advance their improvement, independence, or empowerment. It is an approach which has multi-layered socio-specialized model for universal access to ICTs. It is displayed as seven layers, starting with the fundamental technical components of connectedness and moving upward through layers that inexorably push the essential social framework of access. The seven layers are:

7. Governance

6. Literacy / Social facilitation

5. Service / Access providers

4. Content / Services

3. Software tools

2. Devices

1. Carriage

Even though all elements are important, the most important one is the content /service layer in the middle, since this is where the actual utility is most direct. The upper layers focus on social dimensions and the lower layers focus on technical aspects.

Many practitioners would dispute any necessary connection to university research, regarding academic theorising and interventions as constraining or irrelevant to grassroots activity which should be beyond the control of traditional institutions, or simply irrelevant to practical local goals.

Some of the commonalities and differences may be in fact be due to national and cultural differences. For example, the capacity of many North American (and particularly US) universities to engage in service learning as part of progressive charters in communities large and small is part of a long-standing tradition absent elsewhere. The tradition of service learning is almost entirely absent in the UK, Australia, or New Zealand, (and of limited significance in Canada) where the State has traditionally played a much stronger role in the delivery of community services and information.

In some countries such as the UK, there is a tradition of locally based grassroots community technology, for example in Manchester, or in Hebden Bridge. In Italy and the Netherlands, there also appears to have been a strong connection between the development of local civic networks based around a tradition of civic oppositionism, connected into the work of progressive academics.

In Latin America, Africa and many parts of Asia these efforts have been driven by external funding agencies as part of larger programs and initiatives in support of broader economic and social development goals. However, these efforts have now become significantly "indigenized" (and particularly in Latin America) and "bottom-up" ICT efforts are increasingly playing a leading role in defining the future use of ICT within local communities.

In Canada, The Canadian Research Alliance for Community Innovation and Networking (CRACIN) was established in 2003. Their goal is to explore and archive the status and achievements of CI activities in Canada. It is a research partnership between scholastics, specialists, and public sector delegates.

Networks

There are emerging online and personal networks of researchers and practitioners in community informatics and community networking in many countries as well as international groupings. The past decade has also seen conferences in many countries, and there is an emerging literature for theoreticians and practitioners including the on-line Journal of Community Informatics.

It is surprising in fact, how much in common is found when people from developed and non-developed countries meet. A common theme is the struggle to convince policy makers of the legitimacy of this approach to developing electronically literate societies, instead of a top-down or trickle-down approach, or an approach dominated by technical, rather than social solutions which in the end, tend to help vendors rather than communities. A common criticism that is frequently raised amongst participants at events such as the Prato conferences is that a focus on technical solutions evades the social changes that communities need to achieve in their values, activities and other people-oriented outcomes in order to make better use of technology.

The field tends to have a progressive bent, being concerned about the use of technology for social and cultural development connected to a desire for capacity building or expanding social capital, and in a number of countries, governments and foundations have funded a variety of community informatics projects and initiatives, particularly from a more tightly controlled, though not well-articulated social planning perspective, though knowledge about long-term effects of such forms of social intervention on use of technology is still in its early stages.

Public libraries and community networks

Even though that community networks and public libraries have similitudes in various ways, there are some obstacles that upset the probability of cooperation in the future between them. Albeit both CNs and libraries are concerned with giving information services to the society, an exchange is by all accounts lacking between the two communities. The mission of libraries is frequently rather barely engaged and, with regards to managing people and different institutes, their methodology can be to some degree unbending. Thusly, CN specialists, while institutionally more adaptable, rush to expel the part of public libraries in the community, tending to see the library essentially as a store of books upheld by public subsidizing. Public libraries have a long-standing custom of association with their communities, yet their conditions and concerns contrast from those of community networks (CNs).

Time-sharing

From Wikipedia, the free encyclopedia

In computing, time-sharing is the concurrent sharing of a computing resource among many tasks or users by giving each task or user a small slice of processing time. This quick switch between tasks or users gives the illusion of simultaneous execution. It enables multi-tasking by a single user or enables multiple-user sessions.

Developed during the 1960s, its emergence as the prominent model of computing in the 1970s represented a major technological shift in the history of computing. By allowing many users to interact concurrently with a single computer, time-sharing dramatically lowered the cost of providing computing capability, made it possible for individuals and organizations to use a computer without owning one, and promoted the interactive use of computers and the development of new interactive applications.

History

Batch processing

The earliest computers were extremely expensive devices, and very slow. Machines were typically dedicated to a particular set of tasks and operated by control panels, the operator manually entering small programs via switches one at a time. These programs might take hours to run. As computers increased in speed, run times dropped, and soon the time taken to start up the next program became a concern. Newer batch processing software and methodologies, including batch operating systems such as IBSYS (1960), decreased these "dead periods" by queuing up programs ready to run.

Comparatively inexpensive card punch or paper tape writers were used by programmers to write their programs "offline". Programs were submitted to the operations team, which scheduled them to be run. Output (generally printed) was returned to the programmer. The complete process might take days, during which time the programmer might never see the computer. Stanford students made a short film humorously critiquing this situation.

The alternative of allowing the user to operate the computer directly was generally far too expensive to consider. This was because users might have long periods of entering code while the computer remained idle. This situation limited interactive development to those organizations that could afford to waste computing cycles: large universities for the most part.

Time-sharing

Unix time-sharing at the University of Wisconsin, 1978

The concept is claimed to have been first described by Robert Dodds in a letter he wrote in 1949 although he did not use the term time-sharing. Later John Backus also described the concept, but did not use the term, in the 1954 summer session at MITBob Bemer used the term time-sharing in his 1957 article "How to consider a computer" in Automatic Control Magazine and it was reported the same year he used the term time-sharing in a presentation. In a paper published in December 1958, W. F. Bauer wrote that "The computers would handle a number of problems concurrently. Organizations would have input-output equipment installed on their own premises and would buy time on the computer much the same way that the average household buys power and water from utility companies."

Christopher Strachey, who became Oxford University's first professor of computation, filed a patent application in the United Kingdom for "time-sharing" in February 1959. He gave a paper "Time Sharing in Large Fast Computers" at the first UNESCO Information Processing Conference in Paris in June that year, where he passed the concept on to J. C. R. Licklider. This paper was credited by the MIT Computation Center in 1963 as "the first paper on time-shared computers".

The meaning of the term time-sharing has shifted from its original usage. Up until 1960, time-sharing was used to refer to multiprogramming without multiple user sessions. Later, it came to mean sharing a computer interactively among multiple users. In 1984 Christopher Strachey wrote he considered the change in the meaning of the term time-sharing a source of confusion and not what he meant when he wrote his paper in 1959.

There are also examples of systems which provide multiple user consoles but only for specific applications, they are not general-purpose systems. These include SAGE (1958), SABRE (1960) and PLATO II (1961), created by Donald Bitzer at a public demonstration at Robert Allerton Park near the University of Illinois in early 1961. Bitzer has long said that the PLATO project would have gotten the patent on time-sharing if only the University of Illinois had not lost the patent for two years.

The first interactive, general-purpose time-sharing system usable for software development, Compatible Time-Sharing System, was initiated by John McCarthy at MIT writing a memo in 1959. Fernando J. Corbató led the development of the system, a prototype of which had been produced and tested by November 1961. Philip M. Morse arranged for IBM to provide a series of their mainframe computers starting with the IBM 704 and then the IBM 709 product line IBM 7090 and IBM 7094. IBM loaned those mainframes at no cost to MIT along with the staff to operate them and also provided hardware modifications mostly in the form of RPQs as prior customers had already commissioned the modifications. There were certain stipulations that governed MIT's use of the loaned IBM hardware. MIT could not charge for use of CTSS. MIT could only use the IBM computers for eight hours a day; another eight hours were available for other colleges and universities; IBM could use their computers for the remaining eight hours, although there were some exceptions. In 1963 a second deployment of CTSS was installed on an IBM 7094 that MIT has purchased using ARPA money. This was used to support Multics development at Project MAC.

JOSS began time-sharing service in January 1964. Dartmouth Time-Sharing System (DTSS) began service in March 1964.

Development

Throughout the late 1960s and the 1970s, computer terminals were multiplexed onto large institutional mainframe computers (centralized computing systems), which in many implementations sequentially polled the terminals to see whether any additional data was available or action was requested by the computer user. Later technology in interconnections were interrupt driven, and some of these used parallel data transfer technologies such as the IEEE 488 standard. Generally, computer terminals were utilized on college properties in much the same places as desktop computers or personal computers are found today. In the earliest days of personal computers, many were in fact used as particularly smart terminals for time-sharing systems.

DTSS's creators wrote in 1968 that "any response time which averages more than 10 seconds destroys the illusion of having one's own computer". Conversely, timesharing users thought that their terminal was the computer, and unless they received a bill for using the service, rarely thought about how others shared the computer's resources, such as when a large JOSS application caused paging for all users. The JOSS Newsletter often asked users to reduce storage usage. Time-sharing was nonetheless an efficient way to share a large computer. As of 1972 DTSS supported more than 100 simultaneous users. Although more than 1,000 of the 19,503 jobs the system completed on "a particularly busy day" required ten seconds or more of computer time, DTSS was able to handle the jobs because 78% of jobs needed one second or less of computer time. About 75% of 3,197 users used their terminal for 30 minutes or less, during which they used less than four seconds of computer time. A football simulation, among early mainframe games written for DTSS, used less than two seconds of computer time during the 15 minutes of real time for playing the game. With the rise of microcomputing in the early 1980s, time-sharing became less significant, because individual microprocessors were sufficiently inexpensive that a single person could have all the CPU time dedicated solely to their needs, even when idle.

However, the Internet brought the general concept of time-sharing back into popularity. Expensive corporate server farms costing millions can host thousands of customers all sharing the same common resources. As with the early serial terminals, web sites operate primarily in bursts of activity followed by periods of idle time. This bursting nature permits the service to be used by many customers at once, usually with no perceptible communication delays, unless the servers start to get very busy.

Time-sharing business

Genesis

In the 1960s, several companies started providing time-sharing services as service bureaus. Early systems used Teletype Model 33 KSR or ASR or Teletype Model 35 KSR or ASR machines in ASCII environments, and IBM Selectric typewriter-based terminals (especially the IBM 2741) with two different seven-bit codes. They would connect to the central computer by dial-up Bell 103A modem or acoustically coupled modems operating at 10–15 characters per second. Later terminals and modems supported 30–120 characters per second. The time-sharing system would provide a complete operating environment, including a variety of programming language processors, various software packages, file storage, bulk printing, and off-line storage. Users were charged rent for the terminal, a charge for hours of connect time, a charge for seconds of CPU time, and a charge for kilobyte-months of disk storage.

Common systems used for time-sharing included the SDS 940, the PDP-10, the IBM 360, and the GE-600 series. Companies providing this service included GE's GEISCO, the IBM subsidiary The Service Bureau Corporation, Tymshare (founded in 1966), National CSS (founded in 1967 and bought by Dun & Bradstreet in 1979), Dial Data (bought by Tymshare in 1968), AL/COM, Bolt, Beranek, and Newman (BBN) and Time Sharing Ltd. in the UK. By 1968, there were 32 such service bureaus serving the US National Institutes of Health (NIH) alone. The Auerbach Guide to Timesharing (1973) lists 125 different timesharing services using equipment from Burroughs, CDC, DEC, HP, Honeywell, IBM, RCA, Univac, and XDS.

Rise and fall

In 1975, acting president of Prime Computer Ben F. Robelen told stockholders that "The biggest end-user market currently is time-sharing". For DEC, for a while the second largest computer company (after IBM), this was also true: Their PDP-10 and IBM's 360/67 were widely used by commercial timesharing services such as CompuServe, On-Line Systems, Inc. (OLS), Rapidata and Time Sharing Ltd.

The advent of the personal computer marked the beginning of the decline of time-sharing. The economics were such that computer time went from being an expensive resource that had to be shared to being so cheap that computers could be left to sit idle for long periods in order to be available as needed.

Rapidata as an example

Although many time-sharing services simply closed, Rapidata held on, and became part of National Data Corporation. It was still of sufficient interest in 1982 to be the focus of "A User's Guide to Statistics Programs: The Rapidata Timesharing System". Even as revenue fell by 66% and National Data subsequently developed its own problems, attempts were made to keep this timesharing business going.

UK
  • Time Sharing Limited (TSL, 1969–1974) - launched using DEC systems. PERT was one of its popular offerings. TSL was acquired by ADP in 1974.
  • OLS Computer Services (UK) Limited (1975–1980) - using HP & DEC systems.

The computer utility

Beginning in 1964, the Multics operating system was designed as a computing utility, modeled on the electrical or telephone utilities. In the 1970s, Ted Nelson's original "Xanadu" hypertext repository was envisioned as such a service.

Security

Time-sharing was the first time that multiple processes, owned by different users, were running on a single machine, and these processes could interfere with one another. For example, one process might alter shared resources which another process relied on, such as a variable stored in memory. When only one user was using the system, this would result in possibly wrong output - but with multiple users, this might mean that other users got to see information they were not meant to see.

To prevent this from happening, an operating system needed to enforce a set of policies that determined which privileges each process had. For example, the operating system might deny access to a certain variable by a certain process.

The first international conference on computer security in London in 1971 was primarily driven by the time-sharing industry and its customers.

Time-sharing in the form of shell accounts has been considered a risk.

Notable time-sharing systems

Significant early timesharing systems:

Telecentre

A telecentre is a public place where people can access computers, the Internet, and other digital technologies that enable them to gather information, create, learn, and communicate with others while they develop essential digital skills. Telecentres exist in almost every country, although they sometimes go by a different names including public internet access center (PIAP), village knowledge center, infocenter, Telecottage, Electronic Village Hall, community technology center (CTC), community multimedia center (CMC), multipurpose community telecentre (MCT), Common/Citizen Service Centre (CSC) and school-based telecentre. While each telecentre is different, their common focus is on the use of digital technologies to support community, economic, educational, and social development—reducing isolation, bridging the digital divide, promoting health issues, creating economic opportunities, leveraging information communications technology for development (ICT4D), and empowering youth.

Evolution of the telecentre movement

The telecentre movement's origins can be traced to Europe's telecottage and Electronic Village Halls (originally in Denmark) and Community Technology Centers (CTCs) in the United States, both of which emerged in the 1980s as a result of advances in computing. At a time when computers were available but not yet a common household good, public access to computers emerged as a solution. Today, although home ownership of computers is widespread in the United States and other industrialized countries, there remains a need for free public access to computing, whether it is in CTCs, telecottages or public libraries to ensure that everyone has access to technologies that have become essential.

There are also CTCs located in most of the states of Australia, they are also known as Community Resource Centres (often abbreviated to CRC) that provide technology, resources, training and educational programs to communities in regional, rural and remote areas.

Types

Beyond the differences in names, public ICT access centers are diverse, varying in the clientele they serve, the services they provide, as well as their business or organizational model. Around the world, some telecentres include NGO-sponsored, local government, commercial, school-based, and university-related In the United States and other countries, public access to the Internet in libraries may also be considered within the “telecentre concept”, especially when the range of services offered is not limited to pure access but also includes training end-users. Each type has advantages and disadvantages when considering attempts to link communities with ICTs and to bridge the digital divide. Among the various types:

  • NGO-sponsored telecentres are hosted by an NGO, which manages the center and integrates it, to one degree or another, into the organization's core business.
  • Local government telecentres seek to further local development; they often aim to disseminate information, decentralize services, and encourage civic participation, in addition to providing public ICT access.
  • Commercial telecentres, launched by entrepreneurs for profit, range from the purely commercial cybercafé to the social enterprise, where profit and social good objectives are combined.
  • School-based telecentres can be structured to involve community members during off-school hours, but costs need to be shared by the school system and the community.
  • University-related telecentres can offer social outreach to disadvantaged and community groups, provide training, develop locally relevant content, and establish and facilitate virtual networks.
  • Internet access in public libraries.

Need for telecentres

It is estimated that 40% of the world's population has less than US$20 per year available to spend on ICT. In Brazil, the poorest 20% of the population counts with merely US$9 per year to spend on ICT (US$0.75 per month). In Mexico, the poorest 20% of the society counts with an estimated US$35 per year (US$3 per month). For Latin America it is estimated that the borderline between ICT as a necessity good and ICT as a luxury good is roughly around the "magical number" of US$10 per person per month, or US$120 per year.

Telecentres and international development institutions

In the 1990s, international development institutions such as Canada's International Development Research Centre (IDRC) and UNESCO, sponsored the deployment of many telecentres in developing countries. Both IDRC and UNESCO are still very involved in the telecentre movement. The former telecentre.org programme at IDRC was transferred to the telecentre.org Foundation in the Philippines in March 2010 and continues to support networks of telecentres around the world. Within the Philippines, the Department of Science and Technology (DOST) has rolled-out Tech4ED (Technology for Education, to gain Employment, train Entrepreneurs towards Economic Development). This telecenter program has implemented over 42,000 centers throughout the countryside to promote citizen participation in e-Government services and provide IT education to the masses, specifically, the underserved and marginalized citizens within the country. UNESCO continues to support the growth of community multimedia centers (CMCs), which, unlike most other telecentres, have a local community radio, television or other media component.

Sustainability considerations

In light of the rapidly evolving technologies that support telecentres and in light of the increased penetration of mobile technologies (i.e., cell phones), the telecentre model needs to continuously evolve in order to remain relevant and to continue to address the changing needs of the communities they serve. As mobile communication technologies become more pervasive around the world, including in rural areas, the telecentres may no longer need to provide phone services, yet they may still be very relevant in terms of access to web-enabled e-government services, e-Learning, and basic Internet communication needs (email and web browsing).

Among the various sustainability considerations:

Evolving models — since the local demand for information and communication services is evolving, the telecentre models need to evolve as well. Franchises and other approaches to linking and networking telecentres are proving to be popular.

Evolving technologies — wireless connectivity technologies, beyond VSAT (known to be expensive) are being explored in many communities around the world. These technologies provide new opportunities for connecting communities through telecentres and eventually at the individual household level.

Evolving services — the types of services that telecentres can and should provide is also rapidly evolving. As the fields of eGovernment, eHealth, e-Learning, eCommerce are evolving and maturing in many countries, telecentres need to take advantage of opportunities to extend the benefits to the community at large, through their public access. Some governments are pursuing the deployment of telecentres precisely as a means of ensuring that larger segments of the population are able to access government services and information through electronic channels.

Community stakeholders - identifying leaders among the community who champion the concept of shared services through telecentre mode, play a crucial role as a bridge between the telecentre operator and hesitant villagers. Indeed, There is a maturing period during which community leaders have to invest constant efforts to drive changes of behaviour in the adoption of innovations.

Community involvement is required however, at the initial phase of the telecentre set up, starting with the site selection and creating a sort of empathy and feeling of empowerment. Furthermore, the telecentre should be well rooted in the socio-cultural context of the community.

Networks

The telecentres of today and of the future are networked telecentres, or telecentres of the 2.0 generation. Increasingly, telecentres are not operating as independent, isolated entities but as members of a network. At times, the network takes the form of a franchise. In other circumstances, the network is much more informal.

One such regional network targeted towards Asia-Pacific is, the Asia-Pacific Telecentre Network.

In the United States, more than 1,000 community technology centers were organized under the leadership of CTCnet, a nonprofit association headquartered in Washington, D.C. CTCs are also organized under the banner of state organizations, such as the Ohio Community Computing Network, or city programs such the City of Seattle Community Technology Program. and Austin FreeNet.

Computer technology for developing areas

Computer technology for developing areas is a field focused on using technology to improve the quality of life and support economic development in regions with limited access to resources and infrastructure. This area of research seeks to address the digital divide, which refers to the gap between those who have access to technology and those who do not, and the resulting inequalities in education, healthcare, and economic opportunities.

Computer technology is often given to developing areas through donation. Many institutions, government, charitable, and for-profit organizations throughout the world give hardware, software, and infrastructure along with the necessary training to use and maintain it all.

Opportunity

Developing countries lag behind other nations in terms of ready access to the internet, though computer access has started to bridge that gap. Access to computers, or to broadband access, remains rare for half of the world's population. For example, as of 2010, on average of only one in 130 people in Africa had a computer while in North America and Europe one in every two people had access to the Internet. 90% of students in Africa had never touched a computer. Industrialized countries have an average GNP ten times larger than those of developing countries. The per capita GNP of the United States compared to the per capita of India holds a ratio of fifty to zero. This may be due to differences in economic priorities and social needs. Salaries of clerical staff in developed countries are averaged ten times larger salaries than those in developing countries. Purposes and usage of technology varies drastically due to shifts of priority between industrialized and developing countries. Underutilization of existing computers continues to be a problem in developing countries. Simple designs such as computer memory still have not been implemented or maximized in comparison to industrialized countries today.

Local networks can provide significant access to software and information even without utilizing an internet connection, for example through use of the Wikipedia CD selection or the eGranary Digital Library.

Focusing on Africa

Exploring the introduction of computer technology in Africa

Africa presents a unique cultural climate for the introduction of computer technology not only because of its diverse population, varied geography and multifaceted issues but also because of it singular challenges. Africa is composed of 53 countries many gaining independence since 1950 containing 75 unique ethnic groups and approximately 700 million people. It has been colonized and hence influenced strongly by Europeans from France, Portugal, Britain, Spain, Italy and Belgium except for the countries of Ethiopia and Liberia. Martin & O'Meara describe Africa's diversity and some of the issues that it presents: ethnicity, geography, rural/urban life styles, family life (class levels), access to developed world products, education, and media.

Despite this somewhat overwhelming diversity in Africa, the need for self-determination by Africans as fought for example by the Nigerian's five Ogoni clans during the 1990s over oil rights is paramount. The "bare necessities of life – water, electricity, roads, education and a right to self-determination so that we can be responsible for our resources and our environment" must be respected. Technology such as computers is considered by some to be important in obtaining such self-determination for Africa especially in the area of education. While it has already had an extreme boost through the independence of many of the African countries, more education can lead to water, electricity, roads and more self-determination. Bill Clinton supports the use of technology in education stating, "[s]o, I think that the potential of information technology to empower individuals, promote growth, reduce inequality, increase government capacity, and make citizen interaction with government work better is enormous"[7] And at the same forum, Bill Gates further states, "Out of 6 billion people, somewhat less than 1 billion are using this technology. ... Part of how to do that is by having community access, getting it into schools and libraries, and many of the projects we've done, both here in Africa and around the world have that theme that, although it won't be in the home at first, it will be accessible." Africa is a diverse continent comprising 53 countries with over 75 ethnic groups and a population of approximately 1.3 billion people. The continent has a wide range of geographical features, including deserts, savannas, mountains, and forests. While Africa has seen significant progress in various sectors since gaining independence from European colonial powers, it continues to face multifaceted challenges, including poverty, disease, conflict, and underdevelopment. The continent's education system is also plagued with issues such as inadequate infrastructure, limited resources, and a shortage of qualified teachers. These factors have contributed to low literacy rates in many African countries. Despite these challenges, technology has been identified as a potential tool for addressing some of Africa's development issues. The use of computer technology in Africa has been mainly focused on education, health, agriculture, and e-commerce. However, there are challenges to introducing computer technology in Africa, including limited infrastructure, lack of electricity, and high costs. To overcome these challenges, various initiatives have been undertaken, such as providing community access to technology, and creating partnerships with governments, non-governmental organizations, and the private sector. Despite these initiatives, the adoption of computer technology in Africa remains uneven, with many areas still lacking access to computers and the Internet. Nonetheless, the continent's commitment to embracing technology has led to the development of innovative solutions, such as mobile money and e-learning platforms, that have the potential to transform Africa's economy and society.

South Africa and the Smart Cape Access Project

South Africa has one of the largest and most successful introductions of computers to the residents in Africa with the Smart Cape Access Project initiated in 2000 in Cape Town winning the Bill and Melinda Gates Foundation Access to Learning Award in 2003 (Valentine, 2004. The project piloted 36 computers in six public libraries in disadvantages areas of Cape Town in 2002 with four computers designated for public use for each library. Libraries had the important structure with security, electricity and telephone connections, and known access by the public. Cape Town City Council sought information from librarians to build their project realizing that free Internet access was critical to the projects success including training, a user guide, help desk support and feedback loop. They anticipated that Internet access would "create much-needed jobs for citizens, but ... it can empower people to market themselves, start their own businesses, or gain access to useful information". Funding for the project relied on donations and partnerships from private organizations with extensive volunteer help in accessing open-source software that is available from licensed vendors or free on the Internet. While the project has been plagued by slow Internet speeds, long lines of waiting users, hacking and budgets, the demand for more computers remains high. Residents have used Internet access to build their own businesses using Smart Cape for administration, to obtain jobs sometimes overseas, to create some unsanctioned small-scale ventures such as paying an educated user to write one's resume, to write letters, e-mail, play games, complete homework and do research, and to obtain information such as BMW advertisements among other uses. Older people, unemployed youth and school children have been the most prevalent users of the Internet with 79 percent being men.

With the first phase of the project completed in 2005 and the second phase consisting of monitoring and evaluation of pilot sites just completed in 2007, the roll out of the final phase of the project is underway. Over one hundred thousand people have made use of the Smart Cape Access Project computers' free access since 2002 (Brown, 2007) which is about one fifth increase in overall access to the Internet for the 3.2 million population of Cape Town increasing total access to 17 percent of the residents in 2008 (Mokgata, 2008). However, the project continues to be plagued by budget issues leading to questions about long-term sustainability because of its heavy reliance on donations and volunteers. The project reports did not address the maintenance of the computers or the network which could also be a rather large expenditure. Of further concern is the lack of use by women and girls, which culturally presents a hierarchy problem because men are the public face, and another topic to consider in the future.

Africa and other less successful projects

Unlike the Smart Cape Access Project, many other projects that attempt to introduce computers to Africa fail not only in the sustainability issue but also in training, support and feedback. Although in many cases access to the Internet via cable or wireless and electricity remain overwhelming issues. Less than one percent of Africans access broadband and only four percent use the Internet according to the BGBC in an article about Intel backing wireless access in Africa. The cost of wireless remains prohibitive to most Africans and possibly more important is that there is not an overall "education model" that supports how to integrate forms of hardware to provide the wireless network.

Kenya provides an example pursuing the use of fiber optic cable to connect to the Internet thus being able to lower access costs from $7,500 a satellite-delivered megabyte to $400 from present levels. The Alcatel-Lucent project started at the end of 2007 (two year delivery date) and will piggyback on the expansion of electricity to many rural villages providing Internet access. It will also provide speed that is currently lacking with the satellite connection.

Freeplay Foundation has attempted to address the issue of electricity by first developing battery powered lights for rural areas of Africa piloting a project also in Kenya in 2008."The World Bank estimates that more than 500 million people in sub-Saharan Africa do not have access to electricity supplies that could be used to light their homes" or power computers. Freeplay has also provided a distribution system through women that will provide income in selling, repair and maintenance for customers and is prototyping in Kenya early in 2008. While purchasing the lights may pose a sustainability issue, such inventions could be hopefully tapped for future powering of computers in Africa.

An example of further difficulties surrounding introducing computers in Africa is found in the study of Mozambique one of the poorest nations of the world with 60 percent of its population below the poverty line. Despite their poverty, Mozambicans view their education and access to the Internet as only second to obtaining enough food to eat. This is shown in statistics that identify the increase in computers per hundred inhabitants from .08 to 1.6 in just two years between 1996 and 1998. However, in non urban areas where better off residents might make 40 to 60 US dollars a month, access to the Internet could eat up half of their income so community-owned settings have been instituted with some unknown success. Other pilot programs are also proliferating across the country with unknown results at this time. This lack of data regarding the overall implementation of computers in Mozambique highlights the sustainability issue of computers in Africa as does the following example in Cameroon.

Cameroon was the recipient of the School of Engineering and Applied Science communication technology through a student volunteer organization. Computers were obtained, shipped, refurbished and integrated with teaching computer skills to residents. A recipient was the Presbyterian Teachers Training College which interacts with primary and secondary schools. However, no maintenance or support procedures and facilities were available as part of this effort and information on the continued value of the project are unavailable. Similarly but on a larger scale, Computer Aid, a British charity, has shipped over 30,000 PCs to 87 developing companies and is currently shipping at a rate of 1,000 a month. While it refurbishes donated computers before shipping, it appears to have not follow up to the placement of computers. However, Rwanda seems to be eager to have these computers and is providing a government sponsored Information and Communication Technology policy with access to computers through schools, community and health projects.

While all of these projects are admirable, successful introduction of computers to Africa necessitates more of the United Nations' Millennium Development goals approach which has been agreed to by countries and leading development institutions around the world to promote a comprehensive and coordinated approach to tackling many problems in developing countries ("Microsoft technology, partnerships", 2006). However, by 2008 Bill Gates had changed his perspective on technology solving problems in Africa stating, "I mean, do people have a clear view of what it means to live on $1 a day? ... He openly dismisses the notion that the world's poorest people constitute a significant market for high-tech products anytime soon. ...the world's poorest two billion people desperately need health care right now, not laptops". Here the dilemma is introduced to the mix of feeding people from handouts or providing tools for their own self-determination. As a proponent of self-determination not excluding the benefit of philanthropy, a review of projects discussed above and others merged with the successful Fisher approach to KickStart International could provide a framework for more successful introduction of computers to Africa, possibly skipping to first world technology.

Martin Fisher: a possible business plan

Martin Fisher started KickStart International with Nick Moon in 1991 as a "non-profit organization that develops and markets new technologies for use in Africa". It develops technologies advocating understanding the cultural factors surrounding making money in Africa rather than an approach of giving away technology with expertise that has little to do with Africa's ability to make a living. Moon and Fisher believe that "the poor people don't need handouts, they need concrete opportunities to use their skills and initiative". Fisher further states that "our approach is to design, market, and sell simple tools that poor entrepreneurs buy and use to create profitable new small businesses and earn a decent income". He also stresses the need to build tools that can be supported in Africa using limited materials and assembly methods. They have designed and marketed a number of tools focusing on farming in African countries of Kenya, Tanzania and Mali because 80 percent of the poor are farmers having only two assets: land and the skill of farming. For example, KickStart had created a Hip Pump selling for $34.00 allowing a farmer to use the motion of her or his hips against a lever as a drive mechanism. The pump is capable of lifting water from six meters below the ground to 13 meters above it to allow a farmer to irrigate about three-quarters of an acre in eight hours. Other technologies have included pressing oil seeds, making building blocks from compacted soil, baling hay and producing a latrine cover. These technologies are being mass-produced in Africa. The company has successfully sold over 63,000 pumps (Perlin, 2006) and estimates that 42,000 new micro-enterprises have been started using KickStart equipment such as this pump generating more than 42 million US dollars per year in new profits and wages. Fisher and Moon further estimate that they have helped 200,000 people escape from poverty. They have been successful in Africa because they have focused on:

1. Understanding the culture and environment. 2. Providing income producing tools to create new wealth. 3. Building tools that can be supported in the environment. While KickStart has not talked something as technically challenging as computers, its business plan can be easily adapted to the introduction of computers in Africa. For example, the Smart Cape Access Project has shown widespread success understanding the culture and environment of Cape Town, but still is concerned about sustainability and use by women. Most notable, the project needs to consider how access to the Internet can provide income producing tools to create new wealth and pursue a better maintenance plan. Also of importance is inclusion of women and girls' positive impact in the roll out of technologies for the eventual introduction of computers to Africa.

Although KickStart has not yet addressed the technical challenges of introducing computers to Africa, their business plan can be readily adapted to this goal. The Smart Cape Access Project in Cape Town is a notable success, demonstrating an understanding of the local culture and environment, but it also raises concerns about sustainability and female engagement. It is crucial to consider how access to the internet can offer income-generating tools, create new wealth, and improve maintenance plans. Moreover, promoting the involvement of women and girls will have a positive impact on the rollout of technology and the eventual introduction of computers to Africa.

Sources of hardware

Inexpensive new computers initiatives

Initiatives such as the OLPC computer and Sakshat Tablet are intended to provide rugged technology at a price affordable for mass deployments. The World Bank surveyed the available ICT (Information and communication technologies for development) devices in 2010. The Raspberry Pi is a single-board computers used to promote low-cost educational computing and interfacing applications.

Electronic waste statistics Press Release

Unep, NEMA and Uganda Cleaner Production Centre

Uganda typically has both repair and refurbishers of computers. In some countries charitable NPOs can give tax-deductible donation receipts for computers they're able to refurbish or otherwise reuse. Increased use of technology especially in ICT, low initial cost, and unplanned obsolescence of electrical and electronic equipment has led to an e-waste generation problem for Uganda. A Joint Team from UNEP, NEMA and UCPC, Estimate the current e-waste generated in Uganda at 10,300 tonnes from refrigerators, 3,300 tonnes from TVs, 2,600 tonnes from personal computers, 300 tonnes from printers and 170 tonnes from mobile phones. However, as a result of the ban of used electronics, the accumulation of e-waste from 2010 to 2011 has reduced by a percentage of 40% An e-learning strategy is being developed consultatively involving various stakeholders in the environment sector which yet Uganda has no e-waste recycler with capacity to cab down the problem of accumulation of e-waste.

Problems encountered

Technology leaders like Microsoft co-founder Bill Gates argue that developing areas have more pressing needs than computer technology:

"'Fine, go to those Bangalore Infosys centres, but just for the hell of it go three miles aside and go look at the guy living with no toilet, no running water,' Gates says... 'The world is not flat and PCs are not, in the hierarchy of human needs, in the first five rungs.'"

A 2010 research report from the Governance and Social Development Resource Centre found "Very few ICT4D activities have proved sustainable... Recent research has stressed the need to shift from a technology-led approach, where the emphasis is on technical innovation towards an approach that emphasises innovative use of already established technology (mobiles, radio, television)." However, of 27 applications of ICTs for development, E-government, E-learning and E-health were found to be possible of great success, as well as the strengthening of social networks and boosting of security (particularly of women).

One key problem is the ability of the recipients to maintain the donated technology and teach others its use.

Another significant problem can be the selection of software installed on technology – instructors trained in one set of software (for example Ubuntu) can be expected to have difficulty in navigating computers donated with different software (for example Windows XP).

A pressing problem is also the misuse of electronic waste in dangerous ways. Burning technology to obtain the metals inside will release toxic fumes into the air. (Certification of recyclers to e-Stewards or R2 Solutions standards is intended to preclude environmental pollution.)

Finally, while countries may receive many donations of hardware, software, training, and technical support, internet penetration in developing countries is often extremely low compared with the developed world. However, in recent years, mobile internet has had massive growth in these regions and has become the primary way most people access the internet. Mobile internet penetration is not equal however, with rural areas often having much lower rates of internet access. This furthers the economic and cultural divide between urban and rural areas in developing countries as internet access is becoming more essential to everyday life.
