A of rules that determines how two
computers should communicate with each other. Many different protocols are
used on the internet because the rules for each form of communication it
allows vary considerably. E-mail, for example, requires a particular

should manage the transmission of packets across a network.
Other common Internet protocols are http, ip and ftp. |
