In which generation were computers first built with transistors?

Show Suggested Answer Hide Answer
Suggested Answer: B

The second generation of computers (1956-1963) saw the introduction of transistors, which replaced vacuum tubes used in the first generation. Transistors allowed computers to be smaller, faster, more reliable, and more energy-efficient compared to their predecessors.

I'm a little unsure about this one. I know the generations are defined by the key technologies used, but I can't quite remember when transistors were first introduced. I'll have to think it through carefully.

Okay, let's see. Transistors were a big technological advancement, so it was probably in one of the earlier generations. I'm going to guess B) Second generation.

Hmm, I think this is asking about the generation when transistors were first used in computers. I'll need to think through the different generations to figure out which one it was.
