- a code

- pulse

- input

- additional

- converting

- output

- sequence

Exercise 2.1

Read and translate the text:

The five units of the computer must communicate with each other. This they do by means of a machine language which uses a code composed of combinations are usually represented by ZEROS and ONES where the ONE may be a plus pulse and the ZEROS a minus pulse; or the ONE may be a pulse and the ZEROS a no-pulse.

Numbers are communicated between one unit and another by means of these ONE-ZERO or pulse – no-pulse combinations. The input has the additional job of converting information fed in by the operator into machine language. In other words, it translates from our language into the pulse - no-pulse combinations understandable to the computer. The output has the additional job of converting the pulse – no-pulse combinations into a form understandable to us, such as a printed report.

In addition to date, the input translates instructions needed to perform a given problem into pulse – no-pulse combinations. These instructions are originated by a programmer whose job it is to translate a scientific or business problem presented in human language into a sequence of detailed instructions understandable to the machine.

Exercise 2.2

Answer the questions:

- How do the five units of the computer communicate with each other?

- What is machine language composed?

- What are pulse combinations represented by?

- What has the additional job of converting information fed in?

- What is the job of a programmer?

Exercise 2.3

Read and dramatize the following dialogue:

A: I have just finished secondary school and I want to work at a factory.

B: That is a very good idea. You may learn to be an operator of the electronic computers myself. It is s very good profession.

A: What can you tell me about the factory where you work?

B: Our factory is very big. It is equipped with modern machines.

A: It must be very pleasant to work at such a factory.

B: Certainly it is.

A: What are your wages?(How much do you earn?)

B: My wages are rather high. I’m a qualified operator of the electronic computers.

A: Please tell me, what do you do after working hours? Have you time for the cinema, theatre or concerts.

B: Of course, I have. I go to the theatre on my days off. I like music very much and I often go to concerts. Besides I study English.

A: Do you know English well already?

B: No, I can’t say that I do. But I try to study it regularly and I hope that soon I shall be able to speak English well.
