Communications protocol

Learn about Africa online
In networking, a communications protocol or network protocol is the specification of a set of rules for a particular type of communication.

Different protocols often describe different aspects of a single communication; taken together, these form a protocol stack. The terms "protocol" and "protocol stack" also refer to the software that implements a protocol.

Most recent protocols are assigned by the IETF for internet communications, and the IEEE, or the ISO organizations for other types. The ITU-T handles telecommunications protocols and formats.
