Flow Control A method of controlling the amount of data that two devices
exchange. In data communications, flow control prevents one
modem from "flooding" the other with data. If data comes in
faster than it can be processed, the receiving side stores the
data in a buffer. When the buffer is nearly full, the receiving
side signals the sending side to stop until the buffer has space
again. Between hardware (such as your modem and your
computer), hardware flow control is used; between modems,
software flow control is used.
FTP Short for File Transfer Protocol. The protocol for exchanging
files over the Internet. FTP works in the same way as HTTP
