31. Miniaturization of present day computers has been possible due to the use of- [U.P.P.C.S. (Pre) 2007]

Correct Answer: (b) Integrated Circuit Chips
Solution:

Integrated circuit is a set of electronic circuits on one small plate of semiconductor material normally silicon. After its invention in 1958, it is used in place of transistors in the computer and hence we can say that the miniaturization of present day computers has been possible due to these integrated circuit units.
