Answer Posted / sindhu
Header Checksum: A checksum computed over the header to
provide basic protection against corruption in transmission.
This is not the more complex CRC code typically used by data
link layer technologies such as Ethernet; it's just a 16-bit
checksum. It is calculated by dividing the header bytes into
words (a word is two bytes) and then adding them together.
The data is not checksummed, only the header. At each hop
the device receiving the datagram does the same checksum
calculation and on a mismatch, discards the datagram as damaged.
