Management Information Base
A packet containing ports, addresses, etc. to make sure data being
passed through a bridged network arrives at its proper destination.
negative types of transistors are combined to form a current gate that
in turn forms an effective means of controlling electrical current
through a chip.
A common technique for detecting
for Ethernet is 32 bits long.
The address to send packets.
A design in which memory on a chip is controlled independently of
the CPU.

bits
A naturally occurring phenomena when the electromagnetic field of
one device disrupts, impedes or degrades the electromagnetic field of
another device by coming into proximity with it. In computer
technology, computer devices are susceptible to EMI because
electromagnetic fields are a byproduct of passing electricity through a
wire. Data lines that have not been properly shielded are susceptible
to data corruption by EMI.
See CRC.
Specifies the frame identifier. Alternately is the filter identifier.
A time delay between successive data packets mandated by the
network standard for protocol reasons. In Ethernet, the medium has
to be "silent" (i.e., no data transfer) for a short period of time before a
node can consider the network idle and start to transmit. IPG is used
to correct timing differences between a transmitter and receiver.
During the IPG, no data is transferred, and information in the gap can
be discarded or additions inserted without impact on data integrity.
T
affecting or interfering with each other.
A bus architecture used in the IBM PC/XT and
An Ethernet port connection that allows network hubs or switches to
connect to other hubs or switches without a null-modem, or
crossover, 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),
he disruption of transmitted code caused by adjacent pulses
