Protocols

A protocol is a group of rules that allow computers to connect
across a network. Protocols are the "grammar" that computers use
to speak to each other.
The standard protocol when you connect to the Internet is the IP
(Internet Protocol). This protocol is the usual language of computers
on the Internet.
A protocol also tells how data is sent through a network. The most
frequently used protocols are TCP (Transmission Control Protocol)
and UDP (User Datagram Protocol). Other protocols are less fre-
quently used.
TCP/IP is the basic protocol used by computers that connect to the
Internet. You must know some settings of TCP/IP when you set up
your Firebox® X Edge. For more information on TCP/IP, see "Finding
your TCP/IP properties" on page 15.
