RJ-45 An 8-wire modular connector used for 10Base-T Ethernet
and some telephones.
RMON Remote Monitor MIB defines standard network monitoring
functions and interfaces for communications between
SNMP based management consoles and remote monitors.
The RMON MIB specifies 9 groups of which 4 are
supported by the 2824 hub: statistics, history, alarm, and
events.
Router A program that connects two networks together. Routers
are much more intelligent than bridges and should be used
when packets need to be routed according to their higher
level protocols. Unlike bridges, routers can maintain
several alternate paths and can choose the best path based
on traffic conditions.
RS-232 The EIA (Electronics Industries Association)
Recommended Standard 232 defines a standard way of
transferring serial information by wire using single-ended
line drivers and receivers. RS-232 lines generally include
transmit, receive, ground and various
control lines.
Runt frames Small packets received with FCS or alignment errors.
Runts are the result of collisions occurring on a connected
segment or among stations connected to attached hubs.
Sample A sample represents a poll of objects for an Ethernet
History Table value of a specific statistics on a data source.
SAP See Service Advertising Protocol.
Segment A segment is a separate collision domain. Each Fast
Ethernet segment supports a 100 Mb/s bandwidth. A
multiple segment implementation increases the bandwidth
of a LAN.
Segmentation Segmentation is the process of dividing a network into
multiple collision domains.
