Detect and correct errors in data transmission
Terms in this set (3)
A checksum is an algorithm used to check for errors in data transmission. It works by calculating a numerical value based on the number of bits in a packet of data. This value is attached to the packet. When the packet reaches its destination the same checksum algorithm is applied to the data. If the two checksums don't match it shows that and error has occurred and the receiving computer asks the sending computer to re send the package.
Where the parity bit is set to 1 if the number of bits is even. The extra parity bit will make the number of 1's odd.
