Grammar: The Indefinite Tenses (Active)

Oral Topic: On the History of Computer Development

I. Lexical and Grammar Exercises

1. Read and translate the following international words. Mind the part of speech:

form [fɔ:m] n, v; mechanical [mi'kænikəl] a; logarithm ['lɔgəriɵm] n; automatic [,ɔ:tə'mætik] a; design [di'zain] v, n; prototype ['proutətaip] n; code [koud] n; electromagnetic [i'lektroumæg'netik] a; recommend [,rekɔ'mend] v; practice ['præktis] n; idea [аi'diə] n; standard ['stændəd] n; transistor [tnæn'sistə] n; dynamic [dai'næmik] a; contrast ['kɔntræst] n; characteristic [,kæriktə'ristik] n, a; optical [ɔptikəl] a; expert ['ekspə:t] n, a; structural ['strʌʧ(ə)r(ə)l] a; analysis [ə'næləsis] n; method ['meɵəd] n; distant ['dist(ə)nt] a; extremely [iks'tri:mli] adv; sensory ['sensəri] a.

2. Master the active vocabulary:

1) add [æd] v – складывать, прибавлять

addition(n) – сложение

We add decimal fractions in the same way as whole numbers. The sign for addition is + (plus). The result of addition is known as the sum.

2) multiply ['mʌltiplai] v – умножать

multiplication [,mʌltipli'keiʃ(ə)n] n – умножение

We may multiply numbers in any order, and a good check for multiplication 17 by 15 is to multiply 15 by 17. In the example like 12+15x2 we must perform multiplication before addition.

3) invent [in'vent] v – изобретать

invention (n)  изобретение

In 1671 Leibnitz invented the first machine which performed multiplication by repeated addition. In 1882 P. L. Chebyshev invented the first arithmometer.

4) produce [prə'dju:s] v – создавать, производить

production [prə'dʌkʃ(ə)n] n – производство, продукция

In 1642 В. Pascal produced an adding machine. Later he produced some others, one of them could add six-figures numbers. The University of Pennsylvania is famous for the production of the first electronic computer in 1946.

5) slide-rule ['slaidru:l] n – логарифмическая линейка

After the invention of logarithms in 1614,W. Oughtred constructed the first slide-rule. There are straight and circular (круговая) slide-rules in common use.

6) punch  [pʌntʃ] n, v – 1) пробивка, перфорация; 2) перфорировать

punched card [pʌnʧt ka:d] – перфокарта

The punched card is one of the methods of data input. A high-speed line printer can punch 20 lines per second, each of 80 to 120 characters.

7) digit ['diʤit] n – цифра, разряд

All periods of a number contain three digits (the first period on the left may or may not). Information for a digital computer has to be in the form of digits or numbers.

8) complete [kəm'pli:t] v – заканчивать, завершать

completely (adv) – полностью

In 1937 H. Aiken began to work at the first completely automatic digital computer. He completed it in 1944. The first electronic computer was completed at the Moore School of Engineering, Philadelphia, in 1946.

9) count [kaunt] v – считать

counter ['kauntə] – счетчик

A primitive man knew only ten number-sounds and could count in the way a small child counts today, one by one, with the help of his fingers (пальцы). The store of H. Aiken's computer had 72 counters, each counter could hold 23 digits. In 1874 a Russian engineer V. T. Ordner invented a special counter wheel (колесо) for the arithmometer.

10) generation [,ʤеnə'геiʃ(ə)п] n – поколение There are four generations of computers today, but we are on the threshold (порог) of the fifth generation. Fifth generation computer systems will be smaller, more powerful and more flexible (гибкий).

11) chip [ʧip] n – чип, кристалл

A chip has several hundred thousand electronic components (transistors, resistors, etc.). The microcomputer was the first computer with a single (одиночный) microprocessor chip as the processor.

12) rely [ri'lai] v – полагаться (на – on, upon)

reliable [ri'laiəbl] a – надежный

You may rely on the results of this experiment. The third generation of computers was more reliable than the second one due to the use of silicon (кремниевый) chips instead of transistors.

13) capacity [kə'pæsiti] n – емкость, мощность

storage capacity – емкость запоминающего устройства

The capacity of computer is the quantity of data that its memory unit can hold. The storage capacity of J. Neuman's computer was 4096 words.

14) capable ['keipabl] a – способный, восприимчивый

capability [,keipa'biliti] n – возможность, способность, производительность

The fifth generation computers are capable of speech input. Robots and machines with sensory capabilities are the fifth generation computer systems.

15) size [saiz] n – размер, величина, емкость (памяти)

The first generation computers were very large in size. Floppy (гибкий) disks have several standard sizes.

18. Text A. Read the text and draw a table showing the main stages in the development of computer systems:

On the History of Computer Development

The oldest form of mechanical calculating devices was the abacus1. It remained the only aid to calculation until the 17th century. After the invention of logarithms in 1614, W.Oughtred constructed the first slide-rule in 1630. B. Pascal built an adding machine in 1642 at the age of 19. Later he produced some others, one of them could add six-figure numbers. In 1671 Leibnitz invented the first machine, which performed multiplication by repeated addition.

Ch. Babbage, the English mathematician of the 19th century, was the first who conceived the idea of the automatic machine for complex calculations. He designed his Analytical Engine to perform four arithmetic operations. It was to have three parts: a store, a mill2, and sequence mechanisms3. The store was to hold 1000 numbers, as well as intermediate results and instructions. The mill called up numbers from the store and performed arithmetic calculations with them. It corresponded to the modern processor. The sequence mechanisms, which we would call4 a program, decided which numbers to call up from the store and how to operate on them. A system of punched cards controlled the sequence of operations. Ch. Babbage couldn't translate his ideas into reality because there were no reliable and accurate electrical equipment, but his Analytical Engine was a true prototype of the modern digital computer. Ch. Babbage and Lady Lovelace, Lord Byron's daughter, worked out a coded program. Lady Lovelace was a brilliant mathematician. She believed and fully understood the potentialities of the Analytical Engine. She took an active part in Babbage's experiments. So it is fair to say that she was the world's first computer programmer.

About seventy years passed before the production of the first digital computer, which was similar to Babbage's Analytical Engine. In 1937 Dr. H. Aiken of Harvard University began to work at the first completely automatic digital computer which he called the Mark 1. He completed it in 1944. The Mark 1 was mainly mechanical with some electro-magnetic devices. It was a very large computer, 51 feet long and 8 feet tall. The store had 72 counters. Each counter could hold 23 digits.

The first electronic computer, the Electronic Numerical Integrator and Calculator (ENIAC), was constructed in 1946 at the University of Pennsylvania. The machine used 18,000 vacuum tubes5 for storage and basic functions in arithmetic and logic. Though it was not as large as the Mark 1, it weighed 30 tons and measured 20 by 40 feet. Whereas the Mark 1 could add 2 numbers in one-third of a second, ENIAC could add 5000 numbers in one second.

In 1945 John von Neuman worked out the concept of the stored program. He recommended to store operational instructions and numbers in the same unit in the binary system. ED VAC, EDSAC, UNIVAC were the first computers which put these new ideas into practice.

The first generation computers (from 1940s till 1959) were very large in size and used thousands of vacuum tubes. Though their operations were very rapid in comparison with manual calculations they were slow by today's standards.

The second generation computers began in 1959. The use of transistors instead of vacuum tubes made these computers smaller, more powerful, and more reliable. The second generation also saw the development of programming languages.

The third generation computers started in 1964. There were silicon chips instead of transistors. This advance made possible the invention of the microcomputer in the 1970s, which, because of its low cost, small size, ease of use, large capabilities, is the computer most characteristic of the fourth generation.

All computers of the present time, from the microcomputer to the supercomputer, belong to the fourth generation. This fourth generation is the first in which there are a lot of computers for the application in business, science, medicine, education, or for general use.

The computer revolution is very dynamic. We are on the threshold of the fifth generation of computers. Today researchers in the USA, Western Europe, Japan work at the problems of artificial intelligence6, the application of, natural languages, very large-scale integration (VLSI)7 technologies, etc.

The Fifth Generation Computer System

The fifth generation computer will not only differ in size, speed, and storage capacity. By contrast with the fourth generation systems, which mainly store and process data, it will have the following characteristics: the use of artificial intelligence and natural languages, a speech input, knowledge bases, very large-scale integration technologies, the application of optical fibres1 and videodisks, flexibility and high reliability.

The idea of artificial intelligence is the intensification of man's creative activities with the aid of computers. Artificial intelligence is a machine intelligence. A programmer packs a program in the computer fur the solution of some practical problems. In operation it looks like human intelligence. There are different categories of artificial intelligence uses, such as robots and machines with sensory capabilities, knowledge-based systems and expert systems. A knowledge base is more flexible and less structural than a database. It is able to function with fewer stored facts, to generate2 and infer3 new facts in the process of the problem solution. Expert systems are knowledge-based systems for highly specialized areas: branches of medicine, spectroscopic analysis, and the like.

Artificial intelligence needs new methods of program organization and construction. Very large-scale integration technologies will reduce4 the size of the computer, enlarge its speed and storage capacity. For the solution of these problems some researchers think of optical circuitry5, gallium arsenide6 circuitry, and cryogenic (extremely cold) circuitry. For the solution of still more difficult problems, such as the production of hyper intelligent robots, some researchers discuss the problems of biochip circuitry. This is a revolutionary idea and its realization is in the distant future.

27. A. Reconstruct the paragraphs of the text in logical sequence:


But the most unusual section in the museum is "History of computer development". There is a mechanical calculating device, which was used for the census1 of the population in the USA in 1890. One can also find NEC electronic computer that controlled the Moon expedition of the American astronauts, and the first commercial computer UNIVAC (1951) that predicted2 an election3 victory for president Eisenhower.

Not long ago Oliver Streampel, one of the museum research workers, proposed to build up such a computer that one could walk inside of it. It took a group of enthusiasts a year to construct this museum exhibit. Its keyboard is about 7.5 meters long, and diskettes are 1.8 meter in diameter. All visitors can have a look of the opposite side of the screen and make sense how the computer operates.

The oldest electronic machines of the Boston computer museum were designed soon after World War II. The first IBM personal computer appeared in 1981, but 5–10 years in the computer world seem to be a century.
