R
RARP Reverse Address Resolution Protocol, a TCP/IP protocol that allows
a phys ical 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, sing le-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
subnetmask.
T
(TCP/IP) Transmission Control Protocol/Internet Protocol is a widely used
transport protocol that connects diverse computers of various
transmission methods. It was developed by 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 us ed 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.
