An expansion board inserted into a computer to allow it to be connected
TDR is used to pinpoint flaws and problems in underground and aerial
cable. MDI provides the standard interface to a particular media (copper
or fiber) and is therefore 'media dependent.'
An Ethernet port connection that allows networked end stations (i.e.,
PCs or workstations) to connect to each other using a null-modem, or
crossover, cable. For 10/100 full-duplex networks, an end point (such as
a computer) and a switch are wired so that each transmitter connects to
the far end receiver. When connecting two computers together, a cable
that crosses the TX and RX is required to do this. With auto MDI-X, the
PHY senses the correct TX and RX roles, eliminating any cable
confusion.
The MIB comprises the management portion of network devices. This
can include things like monitoring traffic levels and faults (statistical),
and can also change operating parameters in network nodes (static
forwarding addresses).
The MII accesses PHY registers as defined in the IEEE 802.3
specification.
to a network. Most NICs are designed for a particular type of network,
protocol, and media, although some can serve multiple networks.
The Port VLAN ID value is used as a VLAN reference.
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.
An occurrence that affects the directing of power to different
components of a system.
Manages packet traffic between MAC/PHY interface and the system
host. The QMU has built-in packet memories for receive and transmit
functions called TXQ (Transmit Queue) and RXQ (Receive Queue).
The address from which information has been sent.
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.
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.
A configuration of computers that acts as if all computers are connected
by the same physical network but which may be located virtually
anywhere.
