Why would an implementation of the link layer use error-correcting codes? How would that affect the system?
What will be an ideal response?
Error-correcting codes allow the link layer not only to detect corruption, but in many
cases to recover from corruption. Error-correcting codes reduce the need to retransmit corIntroduction
to Networking 176 rupted frames, but they also increase the size of each frame sent. On a relatively reliable line—one in which corrupted frames occur infrequently—error-correcting codes can actually
slow the speed of transmission.
