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.
