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 Carrier Sense Multiple

Access with Collision Detection (CSMA/CD),implemented as

token-ring, ARCNET, FDDI, or Ethernet. The Router Information

Protocol (RIP),a part of the Transmission Control Protocol/Internet

Protocol (TCP/IP) suite, forwards packets from one network to

another using the same network protocol.

R

RARP

Reverse Address Resolution Protocol, a TCP/IP protocol that allows

a physical address, such as an Ethernet address, to be translated into

an IP address.

RJ-45

RJ-45 connector is used for Ethernet cable connections.

Router

A router is the network software or hardware entity charged

with routing packets between networks.

S

Server

It is a simple computer that provides resources, such as files or other

information.

SMTP

The Simple Mail Transfer Protocol is used for Internet mail.

SNMP

Simple Network Management Protocol. SNMP was designed to

provide a common foundation for managing network devices.

Station

In LANs, a station consists of a device that can communicate data

on the network. In FDDI, a station includes both physical nodes and

addressable logical devices. Workstations, single-attach stations,

dual-attach stations, and concentrators are FDDI stations.

Subnet mask

In TCP/IP, the bits used to create the subnet are called the subnet

mask.
