TCP/IP does.
Latency:
The delay incurred by a switching or bridging device between receiving the frame and forwarding the
frame.
Layer:
In networks, layers refer to software protocol levels comprising the architecture, with each layer
performing functions for the layers above it.
Expressed in bps, the maximum rate at which data can reliably be transmitted over a line using given
hardware.
A temporary connection between source and destination nodes, or between two processes on the same
node.
Management Information Base, a database of network parameters used by SNMP and CMIP (Common
Management Information Protocol) to monitor and change network device settings. It provides a
logical naming of all information resources on the network that are pertinent to the network’s
management.
Media Independent Interface, New standard developed for Fast Ethernet in IEEE 802.3u specification.
