Second-generation computers were generally more reliable than first-generation computers because transistors:
A. Required more space and generated more heat
B. Had no switching ability
C. Were smaller, cooler, and less failure-prone
D. Could only perform mechanical calculations
Correct Answer: C
C is correct because transistors were smaller, consumed less power, produced less heat, and were more durable than vacuum tubes. A states the opposite. B is false because transistors are electronic switches. D is unrelated.
