Protocol Communication on the network is governed by sets of rules
called protocols. Protocols provide the guidelines devices
use to communicate with each other, and thus they have
different functions. Some protocols are responsible for
formatting and presenting and presenting data that will be
transferred from file server memory to the file server’s net
work adapter Others are responsible for filtering
information between networks and forwarding data to its
destination. Still other protocols dictate how data is
transferred across the medium, and how servers respond to
workstation requests and vice versa. Common network
protocols responsible for the presentation and formatting of
data for a network operating system are the Internetwork
Packet Exchange (IPX) protocol or the Internet Protocol (IP).
