American National Standard Code for
Information Exchange (ASCII). The standard
code, using a coded character set consisting of
7-bit coded characters (8 bits including parity
check), used for information exchange between
data processing systems, data communication
systems, and associated equipment. The ASCII

asynchronous transmission. In data
communications, a method of transmission in

of characters, occur during a specific time
interval. However, the start of each character
or block of characters can occur at any time
during this interval. Contrast with synchronous
transmission.
