A checksum is a value used to verify the integrity of a file or a data transfer. In other words, it is a sum that checks the validity of data. Checksums are typically used to compare two sets of data to make sure they are the same. For example , a basic checksum may simply be the number of bytes in a file. What is FCS in networking? Category: technology and computing computer networking. A frame check sequence FCS is an error-detecting code added to a frame in a communications protocol.

Frames are used to send payload data from a source to a destination. How do I fix FCS errors? To resolve this issue, perform these steps:. If possible, hard set the speed and duplex settings on both the port and the connected device. What can cause CRC errors? How does Frame Check Sequence work? What does FCS stand for?
