set of Institute of Electrical and
Electronic Engineers standards for
defining methods of access and control
on LANs
LAN
local area network; a network where
computers are connected in close
proximity, such as in the same building
or office park; a system of LANs
connected at a distance is called a wide-
area network (WAN)
MAC address media access control address; a
hardware address that uniquely
identifies each node of a network
Mbps
millions of bits per second
OEM
original equipment manufacturer; a
manufacturer that typically purchases
components from other manufacturers,
integrates them into its own products,
and sell the products to the public
out-of-band
transmission of control information
outside the bandwidth frequencies that
transfer a network's data
port density
number of ports, either physical or
logical, per network device
PORT
MIRRORING
advanced feature of switching hubs that
allows one port's MAC layer data to be
replicated to another port for monitoring
by a network analyzer
runt
any frame that is shorter than the
minimum valid size of 64 bytes; runt
frames are usually caused by collisions
or faulty network interface cards
