MIR-2

MIR-2 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 MIR-2 rather than just read about it. In short: MIR-2 (Russian: МИР-2) is the version of the MIR computer developed by the Institute of Cybernetics of the Academy of Sciences of Ukrainian SSR under the guidance of Victor Glushkov. It was first produced in 1969.

Key takeaways

MIR-2 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 MIR-2 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of MIR-2 from memory before moving on to harder problems.

Reference excerpt

MIR-2 (Russian: МИР-2) is the version of the MIR computer developed by the Institute of Cybernetics of the Academy of Sciences of Ukrainian SSR under the guidance of Victor Glushkov. It was first produced in 1969.

Overview The speed of the MIR-2 machine is about 12,000 operations per second. The capacity of the random access memory (12-μs circulation cycle) is 8,000 13-bit symbols. The read-only memory has a capacity of about 1.6 million bits with a cycle of 4 μs, which is enough to store several tens of thousands of micro-commands. There is a buffer memory for output information with a volume of 4000 10-bit words. As external devices were used: input from punched tape, output to punched tape, electric typewriter Soemtron, magnetic card drive, vector graphic display with light pen. As the input language in the MIR-2 machine, a special high-level language Analitik was used, which developed the concepts of the MIR-1 built-in programming language and additionally allowed the formulation of tasks with analytic transformations of formulas, allowing analytical expressions for derivatives and integrals.

Worked examples

Example 1 — a first encounter with MIR-2

Start with the simplest possible case. Write down what MIR-2 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 MIR-2 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 MIR-2 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 MIR-2

In research: MIR-2 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 MIR-2 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: MIR-2 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-related introductions in 1969, Soviet computer systems, so understanding it makes those chapters shorter.
In everyday life: Look for MIR-2 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 MIR-2 in simple terms?

Why does MIR-2 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 MIR-2?

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.
