What was the advantage of using transistors instead of vacuum tubes in the second generation computers?

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.
