Glossary • Page G-8
buffer
A memory area used as temporary storage during input and output operations. An example
is the modem's command buffer. Another is the Transmit Data ßow control buffer used for
ßow control and to store copies of transmitted frames until they are positively acknowl-
edged by the receiving modem.
byte
A group of binary digits stored and operated upon as a unit. A byte may have a coded
value equal to a character in the ASCII code (letters, numbers) or have some other value
meaningful to the computer. In user documentation, the term usually refers to
8-bit units or characters. 1 kilobyte (K) is equal to 1,024 bytes or characters; 64K indicates
65,536 bytes or characters.
