What was the advantage of using transistors instead of vacuum tubes in the second-generation computers? a. computers were drastically reduced in size. b. computers no longer produced errors. c. computers became affordable. d. computers could run on electricity.

Using transistors instead of vacuum tubes in the second-generation computers drastically reduced  the size  of the computer size.

Explanation:

Transistors were smaller when compared to vacuum tubes so computers with vacuum tubes were small in size . They were also faster in speed, and cheaper to build. These computers also operates at lower temperature and produces less heat. In 1956, TX-0 was the first computer to build with transistors.Varieties of transistors under a single unit called Integrated Circuit Chip or ICs.  Increase in Memory size, increasing processing speed are the major achievements of ICs.
