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.

(TCP/IP)
Transmission Control Protocol/Internet Protocol is a widely used
transport protocol that connects diverse computers of various
transmission methods. It was developed y the Department of
Defense to connect different computer types and led to the
development of the Internet.
Transceiver
A transceiver joins two network segments together. Transceivers
can also be used to join a segment that uses one medium to a
segment that uses a different medium. On a 10BASE-5 network,
the transceiver connects the network adapter or other network
device to the medium. Transceivers also can be used on 10BASE-
2 or 10BASE-T networks to attach devices with AUI ports.
U
UDP
The User Datagram Protocol is a connectionless protocol that
resides above IP in the TCP/IP suite
ULP
The upper-layer protocol refers to Application Layer protocols
such as FTP,SNMP, and SMTP.
User Name
The USERNAME is the unique name assigned to each person
who has access to the LAN.
Utility
It is a program that performs a specific task.
UTP
Unshielded twisted-pair. UTP is a form of cable used by all access
methods. It consists of several pairs of wires enclosed in an
unshielded sheath.
