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
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.
RTP RTP (Real-time Transport Protocol) is a data transfer
protocol defined to deliver live media to the clients at the
same time, which defines the transmission of video and
audio files in real time for Internet applications.
RTSP RTSP (Real-time Streaming Protocol) is the standard
used to transmit stored media to the client(s) at the
same time, which provides client controls for random
access to the content stream.
