PPPoE
Point-to-Point Protocol over Ethernet. PPPoE is a specification for connecting the users on an
Ethernet to the Internet through a common broadband medium, such as DSL or cable modem. All
the users over the Ethernet share a common connection.
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.
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 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.
