In this video, the parity
In this video, the parity is explained and the use of parity bit in the error detection is explained with examples.
The following topics covered in the video:
0:00 Introduction
1:00 What is Parity? Odd and Even Parity
2:00 Error Detection using Parity Bit
5:03 Limitation of Parity
What is Parity?
Parity Bit is a simple form of error detecting code, where the additional bit is added along with the data bits.
There are two types of Parity:
1) Odd Parity
2) Even Parity
Odd Parity:
In Odd parity, the parity bit is set in such a way that the total number of 1s in the code, including the parity bit is Odd.
Even Parity:
In Even parity, the parity bit is set in such a way that the total number of 1s in the code, including the parity bit is Even.
For error detection, the parity bit is appended with data bits, and the code is sent to the receiver.
At the receiver, the parity checker circuit checks the parity of the received code and detects the error.
Limitations of Parity Bit:
The Parity bit can detect only odd numbers of errors. If there are even a number of errors in the received code, it will remain undetected.
Moreover, the Parity bit can just detect the error in the code (if the number of errors in the received code is odd) but it can't correct the error.

This video will be helpful to all the students of science and engineering in understanding the use of Parity in error detection.
