Reference excerpt

Japan Computer Access Network (JCA-NET) is a Tokyo-based group aligned with the progressivism political philosophy that aims at empowering citizen's activities through the Internet.

History JCA-NET was founded in April 1997 as a member of the Association for Progressive Communications. An earlier group called Japan Computer Access was founded in 1993 in response to the 1990–1991 Gulf War. JCA-NET provides networking tools for non-governmental organizations (NGOs) and social movements, working closely with the Asialink, which is an Asia-wide NGO information and e-mail networks.

Purpose The group calls itself an "Internet service provider for development by people". This internet service was created for people wishing to publicise their activities, and know of other people's movements and activities across the globe. JCA-NET's main objective is to play the role of a "non-profit Internet provider that internationally links the information released by people and NGOs." It works to take technologies like electronic conference rooms, mailing lists and home pages to the alternate, development and campaign sectors. JCA-NET reported about a thousand subscribers on its mailing list in 2006. Japan Computer Access For Empowerment (JCAFE) was also founded in 1993. JCAFE provides Internet technology and skills to support NGOs. Hamada 'Taratta' Tadahisa was chairman of JCAFE in 2006 when it joined the Association for Progressive Communications. At the time he reported 100 members, and support for 400 NGOs in Japan.

Worked examples

Example 1 — a first encounter with Japan Computer Access Network

Start with the simplest possible case. Write down what Japan Computer Access Network claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Japan Computer Access Network before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Japan Computer Access Network ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Japan Computer Access Network

In research: Japan Computer Access Network appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Japan Computer Access Network in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Japan Computer Access Network is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet access organizations, Internet service providers of Japan, Internet stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Japan Computer Access Network outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
