and can also change operating parameters in network nodes (static
forwarding addresses).
MII
Media Independent Interface
The MII accesses PHY registers as defined in the IEEE 802.3
specification.
NIC
Network Interface Card
An expansion board inserted into a computer to allow it to be
connected to a network. Most NICs are designed for a particular type
of network, protocol, and media, although some can serve multiple
networks.
PLL
Phase-Locked Loop
An electronic circuit that controls an oscillator so that it maintains a
constant phase angle (i.e., lock) on the frequency of an input, or
reference, signal. A PLL ensures that a communication signal is
locked on a specific frequency and can also be used to generate,
modulate, and demodulate a signal and divide a frequency.
PME Power Management Event
An occurrence that affects the directing of power to different
components of a system.
SA
Source Address
The address from which information has been sent.
TDR
Time Domain Reflectometry
TDR is used to pinpoint flaws and problems in underground and
aerial wire, cabling, and fiber optics. They send a signal down the
conductor and measure the time it takes for the signal -- or part of the
signal -- to return.
UTP
Unshielded Twisted Pair
Commonly a cable containing 4 twisted pairs of wires. The wires are
twisted in such a manner as to cancel electrical interference
generated in each wire, therefore shielding is not required.
VLAN Virtual Local Area Network
A configuration of computers that acts as if all computers are
connected by the same physical network but which may be located
virtually anywhere.
