Identify the correct order of the following major technological changes in computers, based on the first to the fourth generation of computers.

1.Microprocessors

2.Vacuum tubes

3.Integrated circuits

4.Transistors

A2, 4, 1, 3

B4, 2, 3, 1

C2, 4, 3, 1 ✓ Correct

D3, 1, 2, 4

Correct answer: (C) 2, 4, 3, 1

Explanation

The generations run vacuum tubes, then transistors, then integrated circuits, then microprocessors.

Statement 2, vacuum tubes, powered the first generation.

Statement 4, transistors, defined the second generation.

Statement 3, integrated circuits, marked the third generation.

Statement 1, microprocessors, drove the fourth generation.

Each shift made computers smaller, faster and cheaper.
