Solution

The correct option is B Vacuum Tubes and Valves

Chief component of first generation computer was Vacuum Tubes and Valves.

The first generation computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. • The vacuum tube was developed by Lee De Forest. A vacuum tube is a device generally used to amplify a signal by controlling the movement of electrons in an evacuated space.

The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky, and were unreliable. A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory.

The period of first generation was from 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit).
