When bits are transmitted over the computer network, they are subject to get corrupted due to interference and network problems. The corrupted bits leads to spurious data being received by the destination and are called errors. See more Errors can be of three types, namely single bit errors, multiple bit errors, and burst errors. 1. Single bit error− In the received frame, only one bit has been corrupted, i.e. either changed from 0 to 1 or from 1 to 0. 2. … See more The parity check is done by adding an extra bit, called parity bit to the data to make a number of 1s either even in case of even parity or odd in case of odd parity. While creating a … See more Error control can be done in two ways 1. Error detection− Error detection involves checking whether any error has occurred or not.

WebThe CRC is computed during transmission and appended to the output stream as soon as the last bit goes out onto the wire. But If we put CRC in the header, before transmitting it is necessary to compute CRC bits and then add it.
