Detailed explanation-1: -An error detection technique using a polynomial to generate a series of two 8-bit block check characters that represent the entire block of data. These block check characters are incorporated into the transmission frame and then checked at the receiving end.
Detailed explanation-2: -Convention on the Rights of the Child (CRC)
Detailed explanation-3: -CRC stands for Cyclic Redundancy Check, is an error-detecting code used to detect errors in the frame received. CRC is used to detect errors in the Data link layer. Key Points.
Detailed explanation-4: -Definition(s): A type of checksum algorithm that is not a cryptographic hash but is used to implement data integrity service where accidental changes to data are expected. A method to ensure data has not been altered after being sent through a communication channel.
