| Term | Description |
| CRC | CRC (Cyclic Redundancy Check/Code) is a method of checking for errors in data that has been transmitted over a network. The sending device applies a 16 or 32 bit polynomial division to a datagram (Ethernet uses 32-bit CRC) and appends the resulting CRC before transmitting it. The receiving end applies the same polynomial to the data, compares the CRC results and determines whether the data has been received successfully, or it needs to be retransmited. See also: checksum |
