Question

The 'IC' chip, used in computers, is made of
1. Silicon
2. Chromium
3. Silica
4. Iron Oxide

Answer 1

Correct Answer - Option 1 : Silicon

The correct answer is Silicon.

• The full form of IC Chips is integrated circuit chips.
• It is made up of semiconductor material which is normally silicon.
• It is called an integrated circuit because the components, circuits, and base material are all made together, or integrated, out of a single piece of silicon, as opposed to a discrete circuit in which the components are made separately from different materials and assembled later.
• The first monolithic IC chip was invented by Robert Noyce of Fairchild Semiconductor.

• The period of the third generation was from 1965-1971. The computers of the third generation used Integrated Circuits (ICs) in place of transistors.
• A single IC has many transistors, resistors, and capacitors along with the associated circuitry.
