SNMP:
Simple Network Management Protocol. Protocol for open networking
management.
static route:
A route that is permanent rather than a route that is
dynamically assigned by another router.
STP:
Shielded Twisted Pair. Telephone wire that is wrapped in a sheath to
eliminate external interference.
subnet address:
The subnet portion of an IP address.
subnet mask:
A number that identifies the subnet portion of a network
address. so that IP addresses can be shared on a local area network.
subnet:
An independent network segment, that is, it has the same network
address, but its subnet address is different.
switch:
A data switch connects computing devices to host computers,
enabling multiple devices to share a limited number of ports. An electrical switch

access a remote system at another site.
throughput:
The number of bits, characters, or blocks that are able to pass
through a data communication system.
training:
A process where two modems try to determine the correct
protocols and transmission speeds to establish a communication session.
trellis-coded modulation:
Advanced error correction coding
technique for forward error correction to a modulation scheme by adding an
additional bit to each baud.
UDP:
User Datagram Protocol. A connectionless protocol that converts data
messages generated by an application into packets to be sent over IP.
UNIX:
An operating system developed at AT&T Bell Laboratories.
