Set of Rules and procedure under which network governs.
To request any service or exchange any information between 2 programs there must be an agreed set of
commands and data formats, this is a protocol. So, for example, the commands and data sent between
a World Wide Web browser and a remote server are a protocol. The browser (probably) uses the GET
command follow by the name of the required file (page), this protocol is recognised and understood by the
web server program which responds appropriately. Similarly the format of packets sent between Ethernet
cards and their drivers are a protocol. The programs exchanging messages are called peers.
