RELCOM

RELCOM is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand RELCOM rather than just read about it. In short: RELCOM or Relcom (Russian: РЕЛКОМ, Релком), an acronym for "RELiable COMmunications" is a computer network in Russia. Network It was launched in the Soviet Union on August 1, 1990 in the Kurchatov Institute in collaboration with DEMOS co-operative (although the engineering team at DEMOS at the time consisted mostly of Kurchatov Institute employees, some key members (Mikhail Davidov, Vadim Antonov, Dmitry Volodin) in…

Key takeaways

RELCOM belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect RELCOM to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of RELCOM from memory before moving on to harder problems.

Reference excerpt

RELCOM or Relcom (Russian: РЕЛКОМ, Релком), an acronym for "RELiable COMmunications" is a computer network in Russia.

Network It was launched in the Soviet Union on August 1, 1990 in the Kurchatov Institute in collaboration with DEMOS co-operative (although the engineering team at DEMOS at the time consisted mostly of Kurchatov Institute employees, some key members (Mikhail Davidov, Vadim Antonov, Dmitry Volodin) in the RELCOM team were never employed by Kurchatov Institute). It became one of the first Russian computer networks (and the first commercial internet service provider in the USSR) and its development led to the emergence of the Runet. Initially it was purely e-mail network based on the UUCP protocol. During the Soviet coup attempt of 1991 the Relcom network was used to spread news about the event worldwide while the coup perpetrators were trying to suppress mass media activity through the KGB. Now it is managed by Relcom Business Network Ltd., a Russian ISP.

Worked examples

Example 1 — a first encounter with RELCOM

Start with the simplest possible case. Write down what RELCOM 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 RELCOM 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 RELCOM 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 RELCOM

In research: RELCOM 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 RELCOM 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: RELCOM is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1990 establishments in the Soviet Union, Computer-related introductions in 1990, Computing in the Soviet Union, so understanding it makes those chapters shorter.
In everyday life: Look for RELCOM 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.

Frequently asked questions

What is RELCOM in simple terms?

RELCOM or Relcom (Russian: РЕЛКОМ, Релком), an acronym for "RELiable COMmunications" is a computer network in Russia. Network It was launched in the Soviet Union on August 1, 1990 in the Kurchatov Institute in collaboration with DEMOS co-operative (although the engineering team at DEMOS at the time…

Why does RELCOM matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study RELCOM?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
