Question

IC chips in computers are usually made of which material?

Hint:

Think of the common semiconductor element used to build computer chips.

Answer 1

The correct answer is Silicon.
Integrated circuit (IC) chips used in computers are made mainly of silicon. Silicon is a semiconductor, which means its ability to conduct electricity lies between that of a conductor and an insulator, and this property can be controlled precisely.
Thin wafers of purified silicon are used to build transistors, resistors, and other tiny components on a single chip. This is what allows modern computers to pack millions of components into a very small space.
