Error Detecting Code - Parity bit:
The general idea for achieving error detection and correction is to add some redundancy (i.e., some extra data) to a message, which receivers can use to check consistency of the delivered message, and to recover data determined to be erroneous. An error-detection scheme may be combined with a system for retransmissions of erroneous data
A parity bit is a bit that is added to a group of source bits to ensure that the number of set bits (i.e., bits with value 1) in the outcome is even or odd. It is a very simple scheme that can be used to detect single error in the output.

Q. What is data link of osi model? - The data link layer offers access to the networking media and physical transmission across the media and this enables the data to locate it
