flow control
Flow control is the management of data flow between computers or devices or between nodes
in a network so that the data can be handled at an efficient pace. Too much data arriving
before a device can handle it causes data overflow, meaning the data is either lost or must
be retransmitted. For serial data transmission locally or in a network,
the Xon/Xoff protocol can be used. For modem connections,
either Xon/Xoff or CTS/RTS (Clear to Send/Ready to Send) commands can be used to control data flow. In a network, flow control can also be applied by refusing additional device connections
until the flow of traffic has subsided.
XON/XOFF
Asynchronous transmission protocol in which each end can regulate the data flow by transmitting special codes
Error correction
Hardware or software that can detect and correct an error in a transmission
