Poisk (computer)

Poisk (computer) 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 Poisk (computer) rather than just read about it. In short: Poisk (Russian: Поиск, "The Search") is an IBM-compatible computer built by KPO Electronmash (НПО «Электронмаш») in Kiev, Ukrainian SSR during the Soviet era. It is based on the K1810VM88 microprocessor, a clone of the Intel 8088.

Key takeaways

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

Reference excerpt

Poisk (Russian: Поиск, "The Search") is an IBM-compatible computer built by KPO Electronmash (НПО «Электронмаш») in Kiev, Ukrainian SSR during the Soviet era. It is based on the K1810VM88 microprocessor, a clone of the Intel 8088. Developed since 1987 and released in 1989, it was the most common IBM-compatible computer in the Soviet Union. The basic version did not include an expansion module for parallel or serial ports for connecting a printer, mouse or other devices. The computer had 128 KB (hardware versions 1.0, 1.01, 1.02, 1.03 and 1.05) or 512 KB of RAM (versions 1.04 and 1.06), and displayed CGA graphics. Unusual for an IBM-compatible computer, Poisk utilities cartridges for expanding the system's capabilities in lieu of traditional internal expansion slots found in most similar systems. Despite using CGA-like graphical video modes and 8088-compatible processor running at 5 Mhz, it was not fully IBM-compatible, lacking the Motorola 6845 display and the Intel 8237 DMA controllers, and its performance lagged behind the IBM XT due to the emulation of the alphanumeric modes using NMI and sharing RAM between CPU and display. There were three versions of this computer: Poisk, Poisk-2 and Poisk-3. The machine entered mass production in 1991, just before the Soviet collapse, and production output in the early 1990s reached several tens of thousands units a year.

Technical details

Poisk

The Poisk was made as cheap as possible, being a monoblock with a motherboard and keyboard and an external power supply. The machine came with a KM1810VM88 processor. The CPU speed was 5.0 MHz and the machine came with 128 KB (models 1.0, 1.01, 1.02, 1.03 and 1.05) or 512 KB of RAM (models 1.04 and 1.06), a CGA compatible video adapter and four expansion slots. A monitor and tape recorder could be connected directly to the computer.

Poisk-2

Poisk-2 was compatible with the PC/XT architecture on software and hardware level. The machine came with a KR1810VM86M processor with the possibility of adding a K1810VM87B coprocessor. The CPU speed was 8 MHz and the machine came with 640 KB of RAM (expandable to 2048 KB), an Hercules and Extended CGA video adapter, hard and floppy disk controller based on i82064 and i8272 chips and COM and printer ports.

Poisk-3

Poisk-3 reduced manufacturing costs due to the use of high-integration microcircuits instead of discrete logic. It was produced in small batches in the early 1990s. The machine came with a K1810VM86M processor with the possibility of adding a K1810VM87B coprocessor, or with a Intel 8086-2. The CPU speed was 8 MHz and the machine came with 640 KB of RAM, an EGA video adapter and an IDE HDD controller.

Worked examples

Example 1 — a first encounter with Poisk (computer)

Start with the simplest possible case. Write down what Poisk (computer) 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 Poisk (computer) 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 Poisk (computer) 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 Poisk (computer)

In research: Poisk (computer) 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 Poisk (computer) 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: Poisk (computer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-related introductions in 1989, Computer hardware stubs, Ministry of Radio Industry (USSR) computers, so understanding it makes those chapters shorter.
In everyday life: Look for Poisk (computer) 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 Poisk (computer) in simple terms?

Why does Poisk (computer) 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 Poisk (computer)?

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.
