buffer
A memory area used as temporary storage during input and output operations. An example

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

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.
