In data communications, flow control is the process of managing the speed of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. It provides a mechanism by which the receiver can control the transmission rate so that the receiving node is not flooded with data from the sending node. A distinction must be made between flow control and congestion control, which is used to control the flow of data when congestion has actually occurred.[1] Flow control mechanisms can be classified based on whether or not the receiving node sends feedback to the sending node.

Flow control is important because it allows a sending computer to send information faster than the destination computer can receive and process it. This can happen if the receiving computers have a lot of traffic compared to the sending computer, or if the receiving computer has less processing power than the sending computer.
