Third Generation of Computers used

A. VLSI

B. Integrated Circuits

C. Tansistors

D. Vacuum Tubes

Correct Answer is :

B. Integrated Circuits

Explanation

Third-generation computers used integrated circuits in place of transistors. With the use of integrated circuits, these computers became reliable, generated less heat, were small in size, fast, very less maintenance, and were inexpensive.
