Cyclic Redundancy Check (CRC) 2
Cyclic Redundancy Check (CRC) 2 : (ICT) An error detection and correction method. You will find 'CRC' sections within a data packet such as an Ethernet packet. A simple way of checking if an error has occurred within a data packet is to see if all the bits add up to an even (or odd) number. This is called 'parity checking'. This is fine, but a CRC goes further and is able to detect more than one error within a packet. CRC makes use of complex mathematics to create a 'checksum'. This 'checksum' is used to detect and correct errors
