Protocol

Sometimes referred to as an access method, a protocol is a standard used to define a method of exchanging data over a computer network such as local area network, Internet, Intranet, etc. Each protocol has its own method of how data is formatted when sent and what to do with it once received, how that data is compressed or how to check for errors in data.

One of the most common and known protocols is HTTP (HyperText Transfer Protocol), which is a protocol used to transmit data over the world wide web (Internet). Below is a list of the various protocols currently listed in the Computer Hope dictionary.
