List of home computers

List of home computers 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 List of home computers rather than just read about it. In short: Home computers were a class of microcomputer that existed from 1977 to about 1995. During this time it made economic sense for manufacturers to make microcomputers aimed at the home user.

Key takeaways

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

Reference excerpt

Home computers were a class of microcomputer that existed from 1977 to about 1995. During this time it made economic sense for manufacturers to make microcomputers aimed at the home user. By simplifying the machines, and making use of household items such as television sets and cassette recorders instead of dedicated computer peripherals, the home computer allowed the consumer to own a computer at a fraction of the price of computers oriented to small business. Today, the price of microcomputers has dropped to the point where there's no advantage to building a separate, incompatible series just for home users. While many office-type personal computers were used in homes, in this list a "home computer" is a factory-assembled mass-marketed consumer product, usually at significantly lower cost than contemporary business computers. It would have an alphabetic keyboard and a multi-line alphanumeric display, the ability to run both games software as well as commercial and user-written application software, and some removable mass storage device (such as cassette tape or floppy disk). This list excludes smartphones, personal digital assistants, pocket computers, laptop computers, programmable calculators and pure video game consoles. Single-board development or evaluation boards, intended to demonstrate a microprocessor, are excluded since these were not marketed to general consumers. Pioneering kit and assembled hobby microcomputers which generally required electronics skills to build or operate are listed separately, as are computers intended primarily for use in schools. A hobby-type computer often would have required significant expansion of memory and peripherals to make it useful for the usual role of a factory-made home computer. School computers usually had facilities to share expensive peripherals such as disk drives and printers, and often had provision for central administration.

Worked examples

Example 1 — a first encounter with List of home computers

Start with the simplest possible case. Write down what List of home computers 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 List of home computers 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 List of home computers 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 List of home computers

In research
List of home computers 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 List of home computers 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
List of home computers is common in secondary-school and first-year university syllabi. It links to neighbouring topics Home computers, Lists of computer hardware, so understanding it makes those chapters shorter.
In everyday life
Look for List of home computers 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.
