Detailed explanation-1: -Like the ENIAC, it was programmed using plugboard wiring, and it used 1500 vacuum tubes. Typically, these older machines were controlled with the help of a series of directions encoded on paper tape or by plugboard wiring.
Detailed explanation-2: -It is used as a switch, amplifier or display screen (CRT). Used as on/off switches, vacuum tubes allowed the first computers to perform digital computations. Although tubes made a comeback in high-end stereo components, they have long since been abandoned for TVs and computer monitors.
Detailed explanation-3: -In the history of computing hardware, computers using vacuum tubes were called the first generation; transistors and diodes, the second; integrated circuits, the third; and those using microprocessors, the fourth.
