RMON
Remote Monitoring. A network management standard that allows network information to be gathered at a single workstation. In contrast to the Standard MIB which gathers network data from a single type of Management Information Base (MIB), RMON defines nine additional MIBs that provide a much richer set of data about network usage. For RMON to work, network devices, such as hubs and switches, must be designed to support it.

Routing Table
A table stored in a router or other internetworking device that keeps track of routes to particular network destinations and, in some cases, metrics associated with those routes.
