Text 2. THE FIRST COMPUTERS

In 1930 the first analog computer was built by American named Vannevar Bush. This device was used in Wbrld W&r II to help aim guns.

35 Unit 3. History of Computers

Many technical developments of electronic digital comput­ers took place in the 1940s and 1950s. Mark I, the name given to the first digital computer, was completed in 1944. The man responsible for this invention was Professor Howard Aiken. This was the first machine that could figure out long lists of mathe­matical problems at a very fast rate.

In 1946 two engineers at the University of Pennsilvania, J.Eckert and J.Maushly, built their digital computer with vacu­um tubes. They named their new invention ENIAC (the Elec­tronic Numerical Integrator and Calculator).

Another important achievement in developing computers came in 1947, when John von Neumann developed the idea of keeping instructions for the computer inside the computer’s memory. The contribution of John von Neumann was particu­larly significant. As contrasted with Babbage’s analytical engine, which was designed to store only data, von Neumann’s ma­chine, called the Electronic Discrete Variable Computer, or EDVAC, was able to store both data and instructions. He also contributed to the idea of storing data and instructions in a bi­nary code that uses only ones and zeros. This simplified com­puter design. Thus computers use two conditions, high voltage, and low voltage, to translate the symbols by which we commu­nicate into unique combinations of electrical pulses. Wfe refer to these combinations as codes.

Neumann’s stored program computer as well as other ma­chines of that time were made possible by the invention of the vacuum tube that could control and amplify electronic signals. Early computers, using vacuum tubes, could perform compu­tations in thousandths of seconds, called milliseconds, instead of seconds required by mechanical devices.

ТезЛЗ. SOME FIRST COMPUTER MODELS

1. Babbage’s AnalyticalEngine

In 1832, an English inventor and mathematician Charles Babbage was commissioned by the British government to devel­op a system for calculating the rise and fall of the tides.

Babbage designed a device and called it an analytical engine. It was the first programmable computer, complete with punched cards for data input. Babbage gave the engine the ability to per­form different types of mathematical operations. The machine was not confined to simple addition, subtraction, multiplication, or division. It had its own «memory», due to which the machine could use different combinations and sequences of operations to suit the purposes of the operator.

The machine of his dream was never realized in his life. Yet Babbage’s idea didn’t die with him. Other scientists made at-

Английский язык. Основы компьютерной грамотности 38

tempts to build mechanical, general-purpose, stored-program computers throughout the next century. In 1941 a relay com­puter was built in Germany by Conrad Zuse. It was a major step toward the realization of Babbage’s dream.

2. The Mark I Computer (1937-1944)

In 1944 in the United States, International Business Ma­chines (IBM) built a machine in cooperation with scientists working at Harvard University under the direction of Prof. Aik-en. The machine, called Mark I Automatic Sequence-Con­trolled Calculator, was built to perform calculations for the Manhattan Project, which led to the development of atomic bomb. It was the largest electromechanical calculator ever built. It used over 3000 electrically actuated switches to control its operations. Although its operations were not controlled elec­tronically, Aiken’s machine is often classified as a computer because its instructions, which were entered by means of a punched paper tape, could be altered. The computer could cre­ate ballistic tables used by naval artillery.

The relay computer had its problems. Since relays are elec­tromechanical devices, the switching contacts operate by means of electromagnets and springs. They are slow, very noisy and consume a lot of power.

3. The ABC (1939-1942)

The work on introducing electronics into the design of com­puters was going on.

The gadget that was the basis for the first computer revolu­tion was the vacuum tube, an electronic device invented early in the twentieth century. The vacuum tube was ideal for use in computers. It had no mechanical moving parts. It switched flows of electrons off and on at rates far faster than possible with any mechanical device. It was relatively reliable, and operated hun­dreds of hours before failure. The first vacuum tube computer was built at Iowa University at about the same time as the Mark I. The computer, capable to perform thousands of related computations, was called ABC, the Atanasoff-Berry Comput­er, after Dr.John Atanasoff, a professor of physics and his assis­tant, Clifford Berry. It used 45 vacuum tubes for internal logic and capacitors for storage. From the ABC a number of vacu­um-tube digital computers developed.

39 Unit 3. History of Computers

Soon the British developed a computer with vacuum tubes and used it to decode German messages.

Text 4, FOUR GENERATIONS OF COMPUTERS

The first vacuum tubes computers are referred to as first gen­eration computers, and the approximate period of their use was from 1950 to 1959. UNIVAC 1 (UNF&rsal Automatic Com­puter) is an example of these computers which could perform thousands of calculations per second. Those devices were not only bulky, they were also unreliable. The thousands of vacuum tubes emitted large amounts of heat and burned out frequently.

The transistor, a smaller and more reliable successor to the vacuum tube, was invented in 1948. So-called second genera­tion computers, which used large numbers of transistors were able to reduce computational time from milliseconds to microsec­onds, or millionths of seconds. Second-generation computers were smaller, faster and more reliable than first-generation com­puters.

Advances in electronics technology continued, and micro­electronics made it possible to reduce the size of transistors and integrate large numbers of circuit elements into very small chips of silicon. The computers that were designed to use integrated circuit technology were called third generation computers, and the approximate time span of these machines was from 1960 to 1979. They could perform many data processing operations in nanoseconds, which are billionths of seconds.

Fourth generation computers have now arrived, and the inte­grated circuits that are being developed have been greatly re­duced in size. This is due to microminiaturization, which means that the circuits are much smaller than before; as many as 100 tiny circuits are placed now on a single chip. A chip is a square or rectangular piece of silicon, usually from 1/10 to 1/4 inch, upon which several layers of an integrated circuit are etched or

imprinted, after which the circuit is encapsulated in plastic or metal.
