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). Protocols that dictate the format
of data for transferors the medium include token-passing and
