Question

What is a parity bit?

(a) An error detection is achieved by adding an extra bit

(b) After addition, the carry is found

(c) Bit generated during data transmission

(d) After addition, the total number of bits

The question was posed to me in an interview for internship.

My question is based upon Parity Generators/Checkers in section Combinational Circuits of Digital Circuits

Answer 1

Right choice is (a) An error detection is achieved by adding an extra bit

Easy explanation: A simple form of error detection is achieved by adding an extra bit to the transmitted word. The additional bit is known as parity bits.
