- 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

- 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: 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.

B: My wages are rather high. Im 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.
