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.
