Hightech Information System

Hightech Information System 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 Hightech Information System rather than just read about it. In short: HIS (Hightech Information System Limited; established 1987) is a Hong Kong–based graphics card manufacturer that produces AMD (formerly known as ATI) Radeon graphics cards. Its headquarters are in Hong Kong, with additional sales offices and distribution networks in Europe, the Middle East, North America and Asia Pacific regions.

Key takeaways

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

Reference excerpt

HIS (Hightech Information System Limited; established 1987) is a Hong Kong–based graphics card manufacturer that produces AMD (formerly known as ATI) Radeon graphics cards. Its headquarters are in Hong Kong, with additional sales offices and distribution networks in Europe, the Middle East, North America and Asia Pacific regions. The current distributor in Hong Kong is JunMax Technology.

Products

HIS manufactures and sells AMD Radeon series video cards. They are known for their IceQ cooling technology as well as producing the latest and fastest PCIe cards like AMD Radeon RX 590, RX 5700 and RX 5700 XT. In 2019, HIS launched new versions of the RX 5700 XT in pink and blue.

Worked examples

Example 1 — a first encounter with Hightech Information System

Start with the simplest possible case. Write down what Hightech Information System 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 Hightech Information System 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 Hightech Information System 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 Hightech Information System

In research: Hightech Information System 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 Hightech Information System 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: Hightech Information System is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1987 establishments in Hong Kong, Companies of Hong Kong, Computer companies established in 1987, so understanding it makes those chapters shorter.
In everyday life: Look for Hightech Information System 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 Hightech Information System in simple terms?

Why does Hightech Information System 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 Hightech Information System?

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.
