Protocol to SDRAM
EMM-E6 User’s Guide GL-11
Protocol A set of rules governing the flow of information within a
communications infrastructure. Protocols control
operations such as frame format, timing, and error
correction. See also Architecture.
PVC Polyvinyl Chloride. A material commonly used in the
fabrication of cable insulation. This term is used to
describe a non-plenum rated insulating material. See also
Plenum.
Redundant Extra or contingent. A redundant system is one that is held
in reserve until an occurrence such as a failure of the
primary system causes it to be required.
Repeater A network device consisting of a receiver and transmitter
which is used to regenerate a network signal to increase
the distance it may traverse.
RJ45 A modular connector style used with twisted pair cabling.
The RJ45 connector resembles the modern home
telephone connector (RJ11).
RMIM Repeating Media Interface Module. A term used to
indicate a family of Cabletron Ethernet Media Interface
Modules (See MIM) which are capable of performing
their own repeater functions.
RMON Remote MONitoring. RMON is a network management
standard which provides more detailed network
information and status reporting than SNMP.
Router A router is a device which connects two or more different
network segments, but allows information to flow between
then when necessary. The router, unlike a bridge,
examines the data contained in every packet it receives for
more detailed information. Based on this information, the
router decides wether to block the packet from the rest of
the network or transmit it, and will attempt to send the
packet by the most efficient path through the network.
SDRAM Shared Dynamic Random Access Memory.
