Question

The electronic components used in the third generation of computers are

• A. Vacuum tubes
• B. Transistors
• C. Integrated circuit
• D. None of these

Answer 1

The correct option is C

Integrated circuit

Explanation for correct option:

In the case of option C,

1. The third generation of computers was considered from 1965 to 1971. Transistors were replaced by integrated circuits (ICs) in third-generation computers.
2. A single integrated circuit has several transistors, resistors, capacitors, and circuitry.
3. The IC was developed by Jack Kilby. Because of this development, computers are now more dependable, effective, and small.
4. The operating systems of third-generation computers made advantage of time-sharing, multiprogramming, and remote processing.

Explanation for incorrect options:

In the case of option A,

1. The vacuum tubes are used in the first generation computers to build the logic circuitry. So, this option is inappropriate.

In the case of option B,

1. A computer that uses discrete transistors rather than vacuum tubes is referred to as a transistor computer, sometimes known as a second-generation computer.

In the case of option D,

1. All the options are not incorrect because of the integrated circuit used in the third-generation computers.

Hence, option C is the correct answer.
