Modems

Bit rate

Network hardware; Modems

Also referred to as transmission rate. The number of binary digits, or bits, transmitted per second (bps). Communications channels using analogue modems are established at set bit rates, commonly ...

Bits per second (bps)

Network hardware; Modems

The bits (binary digits) per second rate. Thousands of bits per second are expressed as kilobits per second (Kbps).

Buffer

Network hardware; Modems

A temporary memory area used as storage during input and output operations. An example is the modem's command buffer.

Byte

Network hardware; Modems

A group of binary digits stored and operated upon as a unit. Most often the term refers to 8-bit units or characters. One kilobyte (KB) is equal to 1,024 bytes or characters; 640 KB is equal to ...

Carrier

Network hardware; Modems

The basic signal altered or modulated by the modem in order to carry information.

Character

Network hardware; Modems

A representation, coded in binary digits, of a letter, number, or other symbol.

A data transfer rate generally estimated from the bit rate and the character length. For example, at 2400 bps, 8-bit characters with start/stop bits (for a total of ten bits per character) will be ...
