MEETING A FRIEND

A: Hallo, B.I Where are you going?

B: Hallo, A.! Haven't seen you for ages! I am going to the Institute.

A: Oh! You are a student now! What Institute have you entered?

B: I've entered the Polytechnic Institute.

A: Good for you! And what department do you study at?

B: I study at the Electrical Engineering Department. My speciality is Electronic Computers (Automated Management Systems, Applied Mathematics).

A: You liked mathematics at school, didn't you? They say one should know that subject well to study your speciality.

B: You're right. Mathematics was my favourite subject at school.

A: And you know already what a computer is, don't you?

B: Yes, I do. A computer is a machine which performs a sequence of reasonable operations on information. I also know what simple and complex computers are.

A: It's very interesting! Tell me, please.

B: With pleasure, listen to: a simple computer is an ordinary business adding machine, and a complex computer is a modern electronic digital computer which performs more than 100 mln. operations a second.

A: Can you say, please, what kinds of operations a modern electronic computer performs?

B: Yes, I can. It performs addition, subtraction, multiplication, and division. These operations are called arithmetical operations. But modern computers perform logical operations too.

A: Well, what are they?

B: Logical operations which I know are comparing and selecting.

A: In what capacity will you work after graduating from the Institute?

B: I shall work as a system-engineer (an engineer-mathematician). But I am sorry. I must hurry to the Institute, I'm afraid to be late for the lectures. So long.

A: Wish you luck in your studying. So long!
