Exercise 25. Read the following dialogue, sum up the information and act out
a similar dialogue.
COMPUTERS
A.: They say you have bought a computer.
B.: Yes, now I have got my own computer.
A.: That’s fine. And what type of a computer have you got?
B.: The most common type, a digital one.
A.: By the way, do you know what “a digital computer” means?
B.: It goes without saying. Digital computers deal with numbers. All data —
pictures, sounds, symbols, and words — are translated into numbers inside
the computer.
A.: Yes, you are right. Digital computers are so widespread that the word
“computer” almost always refers to a digital computer. But there are
3 types of computers: digital, analog and hybrid.
B.: I do know about it. Analog computers work with a physical quantity, such
as weight, speed, temperature. They solve problems by measuring a quan-
tity in terms of another quantity. Do you understand what I mean?
A.: Yes, certainly, for example, they measure temperature in terms of the
length of a thin line of liquid in a thermometer.
B.: Good for you. And when are you going to buy a computer? You know so
much about the computers.
A.: You see, I haven’t got such a large amount of money.
B.: Take it easy. You may use my computer.
A.: Thanks a lot.
B.: You are welcome.
