Routing

From Mycomputer Notes

A protocol

Is a set of rules that determines how two computers need to communicate with each other

accross the network. A protocol is also a common denominator by which the different application, host and systems communicate between each others. When two computers commninicate one with another they exchange data messages (i.e data messages could be a connection to a remote machine, email, data and file transfer) To accept a message and act on this message the computer must have a definition of how the message is defined and what it means.

A protocol describes

The format that a message must take. The way i which compuiters must excange a message within the ocntext of a particular activity, such as sending messages across networks.
