10BaseT
Ethernet connector which implements the IEEE standard on 24-gauge,
unshielded twisted
- pair wiring.
AMI
Alternate mark inversion. A bipolar line-coding format in T1 transmission sys-
tems whereby successive ones are alternately inverted.
ANSI
American National Standards Institute. A non-profit organization that coordi-
nates voluntary standards activities in the United States.
asynchronous
A method of data transmission which allows characters to be sent at irregular
intervals by preceding each character with a start bit, followed by a stop bit.
bandwidth
The bandwidth determines the rate at which information can be sent through a
channel (the greater the bandwidth, the more information that can be sent in a
given amount of time).
baud rate
A measure of transmission speed over an analog phone line. Baud rate measures
the shortest signaling elements per second in the analog signal that a modem
sends over an analog phone line. Does not necessarily equal the bit rate.
