Detailed explanation-1: -Transistors are mechanically stronger than vacuum tubes. Vacuum tubes are comparatively less efficient. Transistors have very high efficiency compared to vacuum tubes. For vacuum tubes, the voltage gain is low.
Detailed explanation-2: -Transistors were smaller, cheaper, and longer lasting. They could also be packed into microchips to switch on and off according to different, complex inputs, paving the way for smaller, more powerful computers.
Detailed explanation-3: -The advantages of transistors over vacuum tubes were many–not only were they smaller and quicker, but they used next to no power compared to vacuum tubes. (The vacuum tube-powered ENIAC, for example, reportedly caused brownouts in Philadelphia whenever it was turned on.)
Detailed explanation-4: -The transistor did the same basic job as a vacuum tube-function as an electronic switch that could either be on or off-but was faster, more reliable, smaller, and much cheaper to build. By the end of the 1950s, they had replaced vacuum tubes in computers.
