Let us take a look at the history of computers that we know today. The very first calculating device used was the ten fingers of a man's hands. This, in fact, is why today we still count in tens and multiples of tens.

Then the abacus was invented. People went on using some form of abacus well into the 16th century, and it is still being used in some parts of the world because it can be understood with­out knowing how to read.

During the 17th and I8lh centuries many people tried to find easy ways of calculating. J.Napier, a Scotsman, invented a me­chanical way of multiplying and dividing, which is now the modern slide rale works. Henry Briggs used Napier's ideas to • produce logarithm tables which all mathematicians use today.

Calculus, another branch of mathematics, was independently invented by both Sir Isaak Newton, an Englishman, and Leib­nitz, a German mathematician. The first real calculating ma­chine appeared in 1820 as the result of several people's experi­ments.

In 1830 Charles Babbage, a gifted English mathematician, proposed to build a general-purpose problem-solving machine that he called "the analytical engine". This machine, which Babbage showed at the Paris Exhibition in 1855, was an attempt to cut out the human being altogether, except for providing the machine with the necessary facts about the problem to be solved. He never finished this work, but many of his ideas were the ba­sis for building today's computers.

By the early part of the twentieth century electromechani­cal machines had been developed and were used for business data processing. Dr. Herman Hollerith, a young statistician from the US Census Bureau successfully tabulated the 1890 census. Hollerith invented a means of coding the data by punching holes into cards. He built one machine to punch the holes and others — to tabulate the collected data. Later Hollerith left the Census

Bureau and established his own tabulating machine company. Through a series of merges the company eventually became the IBM Corporation.

Until the middle of the twentieth century machines designed to manipulate punched card data were widely used for business data processing. These early electromechanical data processors were called unit record machines because each punched card contained a unit of data.

In the mid—1940s electronic computers were developed to perform calculations for military and scientific purposes. By the end of the 1960s commercial models of these computers were widely used for both scientific computation and business data processing. Initially these computers accepted their input data from punched cards. By the late 1970s punched cards had been almost universally replaced by keyboard terminals. Since that . time advances in science have led to the proliferation of com­puters throughout our society, and the past is but the prologue that gives us a glimpse of the nature.

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.

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.

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

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.

The necessary data are processed by a computer to become useful information. In fact this is the definition of data process­ing. Data are a collection of facts — unorganized but able to be-organized into useful information. Processing is aseries of ac­tions or operations that convert inputs into outputs. When we*1 speak of data processing, the input is data, and the output is useful information. So, we can define data processing as a se­ries of actions or operations that converts data into useful in­formation.

We use the term data processing system to include the resourc­es that are used to accomplish the processing of data. There are four types of resources: people, materials, facilities, and equip­ment. People provide input to computers, operate them, and use their output. Materials, such as boxes of paper and printer rib­bons, are consumed in great quantity. Facilities are required to house the computer equipment, people and materials.

The need for converting facts into useful information is not a phenomenon of modern life. Throughout history, and even prehistory, people have found it necessary to sort data into forms that were easier to understand. For example, the ancient Egyp­tians recorded the ebb and flow of the Nile River and used this information to predict yearly crop yields.*Today computers con­vert data about land and water into recommendations to farm­ers on crop planting. Mechanical aids to computation were de­veloped and improved upon in Europe, Asia, and America throughout the seventeenth, eighteenth, and nineteenth centu­ries. Modern computers are marvels of an electronics technol­ogy that continues to produce smaller, cheaper, and more pow­erful components.
