Question

2. Transistors are bigger than a vacuum tube.​

Answer 1

Explanation:

transistors use much less power, and lower voltages (so they can be more easily battery powered)

vacuum tubes, because of their filament aka heater, generate a lot more heat than transistors

transistors can be made much smaller; billions can fit into one integrated circuit whereas tube-based computers took up an entire room

transistors last much longer, since tube filaments wear out and cathodes have depletion issues over time, along with other problems

glass vacuum tubes are fragile compared to transistors, can break and also experience microphonics
