Simple Parity check
|
|
|
Two-dimensional Parity check
|
|
|
Checksum
|
|

Explanation:
Detailed explanation-1: -There are three main techniques for detecting errors in frames: Parity Check, Checksum and Cyclic Redundancy Check (CRC).
Detailed explanation-2: -Single-bit error, multiple-bit error, and burst error are the types of error. Simple Parity check, Two-dimensional Parity check, Checksum, and Cyclic redundancy check are error detection methods. When the data is sent from the sender side to the receiver’s side it needs to be detected and corrected.
