Late Collision
A collision that occurs after the first 64 bytes in a frame.
In 10BASE-T networks, late collisions will be seen as
frames with a bad FCS. Causes of Late Collisions are a
faulty NIC or a network that is too long. A too-long
network is one in which the end-to-end signal
propagation time is greater that the minimum legal sized
frame.
Layer
One of seven levels in the Open Systems Interconnection
(OSI) reference model. See OSI.
Link Pulse
A single-bit test pulse that is transmitted at least every
150 milliseconds during idle periods on 10BASE-T link
segments to verify link integrity.
Manufacturer Prefix
The standard partial address used to identify a particular
manufacturer. The prefix of the address is predefined
uniquely for each manufacturer, while the remainder of
the address uniquely identifies the station.
D-6
Master Browser
The Master Browser maintains the browse list, a list of
all servers in the master browser's domain or workgroup.
MBPS
Millions of bits per second. See BPS.
Multicast
Packets that are directed to a group of nodes rather than
to a single node or all nodes. This is contrasted to a
broadcast packet, which is directed to all nodes.
NEXT
Near-end crosstalk; crosstalk between two twisted pairs
measured at the same end of the cable as the disturbing
signal source.
NIC (Network Interface Card)
A network interface card is the adapter card that plugs
into a computer to provide a network connection.
NVP (Nominal Velocity of Propagation)
The speed that a pulse travels along a cable, expressed as
a percentage of the speed of light in a vacuum.
