RIP
Routing Information Protocol. A routing protocol in TCP/IP and NetWare used to identify all attached networks as well as the number of router hops required to reach them (see RFC 1058 and RFC 2453).
Router
A system responsible for making decisions about which of several paths network (or Internet) traffic will follow. To do this it uses a routing to gain information about the network, and algorithms to choose the best route based on several criteria known as routing metrics. In OSI terminology, a router is a Network Layer intermediate system. Historically, routers were called gateways in Internet terminology.
SCPC
Single Channel Per Carrier. A satellite transmission system that employs a separate carrier for each channel, as opposed to freqency division multiplexing that combines many channels on a single carrier.
Popular denomination of an integrated receiver decoder (IRD).
Shell
An outer layer of a program that provides the user interface, or way of commanding the computer.
SLIP
Serial Line Internet Protocol. An older protocol for Internet Protocol connections over telephone lines,
SMDS
Switched
SN
Signal to noise ratio in dB.
SNMP
Simple Network Management Protocol. A widely used network monitoring and control protocol where activity in each network device (hub, router, bridge, etc.), is sent to the workstation console used to oversee the network (see RFC 1157).
Standalone
Static Route
A route that is explicitly configured and entered into the routing table. Static routes take precedence over routes chosen by dynamic routing protocols.
Streaming
1)Transmitting data continuously.
2)An error condition in which a device continuously transmits random data.
SymbolRate
The symbol rate is the rate at which the data leaves the modulator. Symbol rate is expressed in Mbaud (some prefer Msymb).
