Error control involves retransmission of the lost, damaged, or corrupted frame. The scheme is called ARQ, for Automatic Repeat Request.
The general scheme works this way: the sender sends the data. If data arrives without any problems, the receiver sends out an ACK message (acknowledgment). If the data has a problem (corrupt), the receiver sends out an NAK (negative acknowledgment). Upon getting a NAK message, the sender retransmits. There is also a timer; which allows for data retransmission if the original message or ACK or NAK got lost.
