Amplitude modulation (AM)
A method user to impress information signals on a sine wave by varying
its strength according to patterns by the information signals.
Analog transmission
The transmission of information by means of a continuously varying
electrical signal.
Carrier
A continuous frequency signal that is modulated by the patterns
produced by a separate information signal.
Bit
The smallest element of a computer code which given a numerical value
of either 1 or 0. A single electrical pulse in a group of pulses.
Baseband signaling
The transmission of an analog signal at its original frequency. The
direct transmission of unmodulated digital pulses over a comm. line.
Asynchronous transmision
A method of transmitting computer data one character at a time. The
length of time between character is variable.
Attenuation
A reduction in the strength of an electrical signal that occurs during
transmission
bps (bits per second)
The measurement of the rate at which digital information signals are
transmitted.
Address
Any goup of bits that identifies a network node as a separate,
identifiable location.
Bandwidth
The range of frequencies of an electromagnetic energy form measured
from the lowest to the highest frequencies.
Broadband link
A transmission channel with a wide frequency range that is divided into
separate communication channels.
Bisync
A common name for Binary Synchronous Communications Control, a half-
duplex communications line.
