Analog to Digital - Technical MCQs

Q1:

Most of the input signals applied to a computer for storage or processing are digital in nature.

A True

B False

ANS:B - False

Computer can store all the values in digital form. But the signal applied are by nature analog in nature and computer predict it as digital form. For example for a particular digital machine the voltage greater than 5V is count as 1 (High) and voltage below 5V is count as 0 (low). But the signal will have an analog value as 4.86V count as 0 and 5.68 is count as 1. So, the given statement is wrong. Hence correct option is B.
