Reading for an examination)

A. I say, Max, do you think the examination questions to be difficult?

B. Some of them seem to be difficult and some to be rather easy to answer.

A. Do you find it hard to tell me about the computer organization?

B. Oh, this is the easiest question for me to answer. Let me try. Any computer consists of 5 basic units: the input unit, memory unit, the arithmetic logic unit, the control unit, the output unit.

A. That’s right. And now would you explain the notion of programme, please.

B. With pleasure, sir. Programme is a set of instructions prepared by one or more persons for each job a computer is to do. Any more questions?

A. Yes, and this time the question seems to be more sophisticated. I mean the computer range. But don’t try to have a quick look at your note-book.

B. Well, stop moralizing. Don’t you know me to be the cleverest and the most hard-working person in our group?

A. And the most modest one!

B. So as far as the computer range is concerned, we know the computers to be the microcomputers and maxicomputers. And that’s all I can tell you, sir.

A. It’s not so bad. But we have so many questions to clear up before our exam. Let’s better go to the library reading-hall. There is a lot of special literature on the subject being of great help to us.

B. You are right, as usual. Don’ waste time. Time is money, they say.

A. You are always joking. But reading for an examination is no laughing matter.

At the examination)

Professor: Your first question to answer is about the problem of turning heat into electricity.

Student: The usual way of producing electricity is by means of generators that get their power from steam or water turbines. Another way of producing electricity is nuclear power. The heat energy produced by the reactor is used to make steam; the steam gives mechanical energy to generators which produce electrical energy.

Professor: That’s good. And what can you tell me about the field of application of electricity?

Student: Electricity made possible the engineering progress of today. It serves as the basis of modernizing industry, increasing equipment efficiency, mechanizing and automating progress.

Professor: And what about household appliances?

Student: Electricity has become a part of our life. Electric motors operate washing machines, refrigerators, vacuum cleaners, electric razors, electric cookers and kitchen units, air-conditioners. All we have to do is turn a switch and electric devices will be doing their job for us.

Professor: That will do. I see you have read a lot for your examination. Your mark is a five.

Automation

The machine is known to be the major and efficient means of labour in modern production. The machine-building industry produces various kinds of machinery and machine-tools to meet the requirements of engineering branches as well as the light and food industries. The engineering industry is characterized by such features as increased capacities and speeds of machinery, the replacement of mechanical control systems by electrical and hydraulic ones. It is characterized by simplification of machinery design, an increasing use of automatic devices and the introduction of programmed control techniques on a mass scale. Automation of production means producing automatic and semiautomatic machinery, machine-tools, numerically controlled machines based on microprocessors and microcomputers, installing transfer lines. It is a key production for the building of the material and technical base of economy. What is automation? Shortly speaking, automation consists of four integral parts: transfer machines, automatic assembly, communication engineering and control engineering. There is difference between mechanization and automation. In automation the functions of control, maintaining machines are transferred to other machines while in mechanization these functions are transferred to the working mechanisms.

The mechanized and automated production lines replace the work of a tremendous number of workers. There are fully automated enterprises such as chemical and hydro-power plants. The development and mass production of new types of computer technology makes it possible to exclude man from the entire technological processes.

The so-called flexible manufacturing systems (FMS) are able to meet the demands of industry. They are considered to be the future of the automated plant.
