Bit Rate - US Robotics 002605-00 Manual

bit rate

Also referred to as transmission rate. The
number of binary digits, or bits, transmitted per
second (bps). Communications channels using
telephone channel modems are established at
set bit rates, commonly 2400, 4800, 9600,
14,400, 28,800 and higher.
bits per second ( bps)
The bits (binary digits) per second rate.
Thousands of bits per second are expressed as
kilobits per second or Kbps.
buffer
A memory area set aside to be used as
temporary storage during input and output
operations. An example is the modem's
command buffer.

kilobyte (KB) is equal to 1,024 bytes or
characters; 640 KB indicates 655,360 bytes or
characters.
carrier

alter to communicate data across telephone
