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
