The computer is no doubt the most amazing achievement of mankind. It is a data storage system created by man. A human tells the machine what to do, when to do it and how it should be done.

The word computer comes from a Latin word which means to count. 2. _______. Knotted ropes, marks in clay, the abacus are all methods of keeping track of numbers.

In 1833 an English inventor and mathematician Charles Babbage, professor of Cambridge University designed the first computer. 3. _______. If Babbage had been able to get enough money to build the computer, the analytical engine would have been as big as a locomotive. It would have been able to store 1,000 50-digit numbers.

During the 70 years following Babbage’s death in 1871, computer scientists improved on Babbage’s original idea. In 1939, Harvard University physicist Howard Aiken built the forerunner of today’s computer. 4. _______. It was much slower than later computers, which use electronic components instead of switches.

In our country the first electronic digital computer MACM was constructed by the Ukrainian Academician S. O. Lebedev in 1950. Such computers as BESM, Minsk, Ural, Razdan-3, M-20, M-220, Nairi-3, Strela, Dniepr were created in our country.

5. ______. An analogue computer computes by using physical analogue of numerical measurements. A digital computer computes by using numbers or digits. A hybrid computer is a machine which combines some of the properties of digital and analogue computers.

Invention of electronic computers is one of the greatest achievements of mankind. The significance of it can be compared with the invention of the steam-engine and the utilisation of atomic energy.

Nowadays computers greatly increase man’s thinking capabilities of planning, analysing, computing and controlling. Hundreds of computers are already in daily use. They penetrate almost into all spheres of our modern society, from nuclear energy production and missile design to the processing of bank checks, weather forecasting, manufacturing, research and medical diagnoses. Computers are everywhere. 6. _______.

Computer technology is a rapidly growing industry. According to the technical experts it is very educational. They say that computers help children to learn much more quickly. In some Japanese elementary schools there are already lessons on using computers. For older children the electronic diary was produced. Many young people in Tokyo use it for taking notes, doing homework, drawing and keeping telephone numbers. There’s also some equipment which is like an electronic teacher. This computer answers questions on all scholastic subjects from biology to geography. At home the computer is becoming a kind of technological grandmother.

Computers are fast and efficient machines that can do in seconds what would take a person hours, days, or even months. They have become an important part of our lives.

Since the first-generation computers were designed and built in the 1940s and 50s, computers have become very sophisticated and complex machines. Computers have decreased greatly in price. Computer technology has changed the way we live and created problems. Computers have created new ways to commit fraud, and they have posed new ethical problems. Every day we hear about new uses of the computer. Computers are used more and more in business, industry, agriculture, at home.

An important use of computers is in education. It is called computer assisted instruction. It is becoming more and more popular at all levels of education from pre-school to university. There are computer games that teach 3-year-olds how to read and spell. Starting in kindergarten, computers are used in the classroom to allow students to work without a teacher on subjects ranging from mathematics to reading, and from history to English.

Many people fear the computer because they do not really understand it. “Computer literacy” is a new term used to describe a working knowledge of the computer and a familiarity with the terminology. The growth of computer technologies has eliminated many jobs. But computers create as many jobs as they take away.

So, what is a computer? A computer is a high-speed electronic machine used for word and data processing. In its simplest configuration, a computer system consists of three components. These parts are an input device (keyboard), the central processing unit (CPU), and an output device (printer). These are usually referred to as “hardware”. Software is needed to make this hardware capable of performing useful operations. Software is a collection of different types of programs that make the computer run.

The keyboard is the most common input device. Once the programs and data are typed on the terminal keyboard, they are transferred into the computer memory. The typed material appears either on paper or on a screen.

The central processing unit is the brain and the heart of the computer system.

The memory of the computer is its storage area. The capacity of the memory is measured in thousands of characters, usually referred to as kilos of bytes. Each byte can store one character. For example, if the word English were to be stored in memory, it would use seven bytes. Each letter would use one byte for a total of seven. A small system with 8 K bytes (8 kilos of bytes) has a main storage area of approximately eight thousand characters.

The control unit is the chief executive of the computer system. All the other components of the computer are directed by the control unit. It supervises all the operations in the system. The control unit gets the instructions from memory, executes them, and orders the input and output devices to perform. The memory and the control unit are parts of the central processing unit.

Task 5.

універсальний комп’ютер, значно більша швидкість та точність, блок пам’яті, надсилати сигнал, обробляти дані, дослідницькі центри, широко застосовувати, блок управління, важлива частина життя, складні машини, значно подорожчати, допоміжні інструкції, “комп’ютерна грамотність”, обробка даних, контролювати операції системи.

UNIT 5	TECHNOLOGICAL DEVELOPMENT AND ECOLOGY PROBLEMS
Task 1.	Think about the answers to the following questions: What is environment Think about interrelations between man and nature. Are there any ecological problems? If so, what solutions can you propose?

Task 2.

Working in group discuss if there is any connection between economic-technological development and ecology problems and present your ideas in a few words.

Task 3.

Before reading the text pay attention to the pronunciation of the ending ‘-ed’:

a) remained, changed, increased, conquered, tried, solved, suffered, survived, dared, struggled, combined;

b) developed, worked, perished;

c) complicated, interrelated, protected, activated, effected, polluted, landed, resulted.

Task 3.

You are going to read about economic-technological development and ecology problems. Define whether the following statements based on the text are true “+” or false “-”.

1. During centuries man was trying to live in harmony with nature, but did not survive.

2. A lot of animal and plant species suffer from industrial activity of a man.

3. The main problem of environmental protection is the acid rains.

4. To solve the ecological problem we have to work on cooperation.

For millennia man had to struggle against nature in order to survive and develop. For many thousands of years man remained weak while nature was omnipotent.

However as economy developed, the scientific and technological revolution increased the correlation of forces between man and nature changed. Man gradually grew so strong that he dared to declare himself the “king of nature” and contemplated conquering and remoulding nature to his liking. In his conquer of nature man became so great that his economic achievements began to have an increasingly negative effect on nature, on the biosphere.

Road and factory constructions, industrial development take away to seven million hectares of land every year. Forest disappears at a rate of 20 hectares a minute. According to the International Union for Conservation of Nature and Natural Resources, 76 animal species and several hundred plant species of the Earth became extinct in the last 60 years alone.

Today animals and plants perish not so much due to their physical extermination by hunting, fishing, or open-cast mining, as due to the production of chemical and other industrial pollutants, poisoning the biosphere.

Each year the world economy ejects into the atmosphere over 200 million of carbon monoxide, more than 50 million tons of diverse hydrocarbons, 120 million tons of ash and nearly 150 million tons of sulphur dioxide. They fall back upon the Earth in the form of “acid rains”.
