Ultra 24

Ultra 24 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 Ultra 24 rather than just read about it. In short: The Ultra 24 is a family of computer workstations by Sun Microsystems based on the Intel Core 2 processor. The Sun Ultra 24 launched in 2007, and shipped with Solaris 10 pre-installed.

Key takeaways

Ultra 24 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 Ultra 24 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ultra 24 from memory before moving on to harder problems.

Reference excerpt

The Ultra 24 is a family of computer workstations by Sun Microsystems based on the Intel Core 2 processor. The Sun Ultra 24 launched in 2007, and shipped with Solaris 10 pre-installed. Other than Solaris, it is officially compatible with various flavours of Linux as well as Microsoft's Windows XP and Windows Vista.

Worked examples

Example 1 — a first encounter with Ultra 24

Start with the simplest possible case. Write down what Ultra 24 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 Ultra 24 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 Ultra 24 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 Ultra 24

In research: Ultra 24 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 Ultra 24 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: Ultra 24 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-related introductions in 2007, Computer hardware stubs, Sun workstations, so understanding it makes those chapters shorter.
In everyday life: Look for Ultra 24 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 Ultra 24 in simple terms?

The Ultra 24 is a family of computer workstations by Sun Microsystems based on the Intel Core 2 processor. The Sun Ultra 24 launched in 2007, and shipped with Solaris 10 pre-installed.

Why does Ultra 24 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 Ultra 24?

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.
