TEXT A. MICROCOMPUTER AND MICROPROCESSOR DESIGN

Since the transistor was invented, no single electronics innovation1 has had such an impact2 as microcomputer. Powered by tiny semiconductor chips3 containing computing elements with the same power only and functions previously found in large scale computers, these microcomputers systems are now being applied to literally4 thousand of application. Microprocessors are automating assembly lines, providing the heart of sophistical electronic games, making “intelligent”5 computer peripherals even faster. This revolution is occurring because microcomputers are very inexpensive, easy to implement into a system, and significantly reduce the time and cost of product development6.
The microcomputers were the first computers to use a single microprocessor chip as the processor. Personal computers and small business computers are microcomputers. 8-bit microcomputers usually support only one user terminal and have a maximum of 64 KB of memory. 16-bit microcomputers may support several user terminals and usually have maximum of 1 million bytes of memory. As the power of microcomputers increases, they can be used in two ways. They can be used either as a central computer (providing processing for several user terminals), or as a more powerful single computer for an individual user.

Notes

1innovation – новшество
2an impact – зд. влияние
3Powered by tiny semiconductor chips – приводимые в действие крошечными полупроводниковыми кристаллами (чипами)
4literally – буквально
5“intelligent” – «умный» (зд. применительно к вычислительной машине)
6product development – зд. выпуск продукции
