1. Computers have devices to accept information in the form of instruc-
tions. 2. They have programmes to provide information needed to solve the
problem. 3. Computers have devices to feed information
in and get results
back. 4. Computers have circuits to make thousands of logical decisions with-
out becoming tired. 5. Computers have devices to print the information.

Exercise 23. Make up special questions according to the models, and answer
them to streamline your speaking skills.
Model A:
That garget was used as the base for the first computer.
What was used as the base for the first computer?
1. The electronic device was invented in the 20th century. 2. The first vac-
uum-tube computer was built at that time. 3. The
first vacuum-tube computer
was referred to as the first-generation computer. 4. A transistor was used in the
second-generation computer. 5. An integrated circuit
was used in computers
of the third generation.
Model B:
Computers can process information.
What can computers process?
