Vacuum tubes

Detailed explanation-1: -Detailed Solution. The chief component of the first generation computers was vacuum tubes. The period of the first generation was between 1946 to 1959. Vacuum tubes were used as the main component of memory in this generation of computers.
Detailed explanation-2: -The Atanasoff–Berry computer, a prototype of which was first demonstrated in 1939, is now credited as the first vacuum-tube computer.
Detailed explanation-3: -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.
Detailed explanation-4: -From top to bottom, the components are the anode, the cathode, and the heater filament. Vacuum tube diodes contain only two electrodes (besides the heater): A cathode and an anode. The filament heats up the cathode, producing a space charge.
