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.
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.
