Ivel Ultra

Ivel Ultra 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 Ivel Ultra rather than just read about it. In short: The Ivel Ultra is an 8-bit Yugoslav Apple II compatible computer designed by Branimir Makanec and developed by Ivasim Electronika in the 1984s. It was produced in two different versions: the first version has a brown case and ran from 1984 to 1986, the second has a white case and ran from 1987 to 1990.

Key takeaways

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

Reference excerpt

The Ivel Ultra is an 8-bit Yugoslav Apple II compatible computer designed by Branimir Makanec and developed by Ivasim Electronika in the 1984s. It was produced in two different versions: the first version has a brown case and ran from 1984 to 1986, the second has a white case and ran from 1987 to 1990. The machine was equipped with one or two 5.25" floppy disk drives. It came with an Apple I compatible BASIC language. The operating system, called IDOS, is compatible with Apple DOS 3.3.

The Ivel Ultra could be equipped with a second Zilog Z80 processor, in order to offer compatibility with the CP/M operating system.

Specifications CPU: MOS Technology 6502 at 1 MHz ROM: 12 KB (BASIC language interpreter and machine language monitor) RAM: 64 KB Graphic mode: 280 x 192 pixels, 6 colors Text mode: 40 x 24 Operating system: IDOS, compatible with Apple DOS 3.3, CP/M (with an added Z80 CPU)

Worked examples

Example 1 — a first encounter with Ivel Ultra

Start with the simplest possible case. Write down what Ivel Ultra 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 Ivel Ultra 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 Ivel Ultra 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 Ivel Ultra

In research: Ivel Ultra 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 Ivel Ultra 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: Ivel Ultra is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-related introductions in 1984, Computer hardware stubs, Croatia stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Ivel Ultra 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 Ivel Ultra in simple terms?

Why does Ivel Ultra 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 Ivel Ultra?

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.
