Broadcast
The process of sending a message to all stations on a network.
Collision
Condition in which two packets transmitted over a medium
interfere with each other. Their interference makes both unin-
telligible. The transmitting devices have to halt transmission for
a random period of time before trying to send data again. Note
that collisions do not occur on full-duplex connections.
Driver
Program that enables the network operating system to commu-
nicate with LAN cards.
Frame
Group of bits that include data plus control information.
Generally refers to a link layer (layer 2) protocol.
I/O Address
Input/output address; starting address for data input and output.
IEEE 802.3 standard
Standard developed by the IEEE (Institute of Electrical and
Electronics Engineers) for physical and electrical connections in
local area networks.
Interrupt
Signal that causes a momentary switch of control from program
to operating system when input or output is required.
Loopback
Diagnostic test in which a signal is transmitted across a medium
while sending device waits for its return.
