error detection- check sum the checksum

Error Detection- Check Sum

The Checksum generator are subdivides the data unit into equal segments of "n" bits (usually 16)
These segments are added utilizing one's complement arithmetic in such a way that the total is also "n" bits long
Total is complemented as well as appended to the end of the original data unit as redundancy bits called the check sum field
