Serial communication
Type of data transfer From Wikipedia, the free encyclopedia
Serial communication is a term used to describe systems used for telecommunications, as well as certain technologies used for computing. When using serial communication, only one bit is transferred at a time, for example over a communication channel or computer bus. This is different to parallel communication, where several bits are sent at the same time. Many computer networks, as well as many lines where data is transferred over a long distance use serial communication.
