Question 33

What is an input unit? Give its significance.

Answer

An input unit takes the input and converts it into binary form which is directly understood by the computer.

Computers only understand binary language that uses just two symbols: 1 for ON and 0 for OFF. The input unit translates raw data from external sources into binary language that the computer understands. Without this conversion, the computer would not be able to understand or process the data provided.
