Текст.

Computers may have a short history but prior to their development,

there were many other ways of doing calculations. These calculations were done using devices that are still used today; the slide rule being a perfect example, not to mention the ten fingers of the hands. These machines, unlike computers, are non-electronic and were replaced by faster calculating devices. It wasn’t until the mid-1940s that the first digital computer was built. The post-war industrial boom saw the development of computers take shape. By the 1960s, computers were faster than their predecessors and semiconductors had replaced vacuum tubes only to be replaced in a few years by tiny integrated circuit boards. Due to microminiaturization in the 1970s, these circuits were etched onto wafer-thin rectangular pieces of silicon. This integrated circuitry is known as a chip and is used in microcomputers of all types.

It has been forecasted that exceptionally faster and smaller computers

will replace those in use today.
