The rate of characters, which can be transmitted over a telecommunications line. Often measured in bits per second (bps) or baud.
Capacity refers to the amount of information that can be transmitted over a wire or cable in one second.
The maximum data rate that can be reliably transmitted over a line.
Expressed in bps, the maximum rate at which data can reliably be transmitted over a line using given hardware.
Maximum transmission capacity of a line, expressed in bits per second or baud
The rate at which individual bits are transmitted on a telephone connection. A modem's line speed may be set at 14,400 bits per second, an ISDN line at 64,000 bits per second. Line speed does not take into account whether the data it is sending has been compressed to increase actual Throughput.
The maximum rate at which data can be reliably transmitted over a line; varies with the capability of the modem or hardware device that performs the transmitting.
