Asynchronous - Data - A form of serial data communication which is not clocked. To keep the bit stream synchronized start and stop bits are used. RS-232 computer data is commonly asynchronous data. In contrast to synchronous data.

Asynchronous - Transmission - Transmission in which the interval between transmitted characters may be of unequal length. Data transmission and timing is controlled by start and stop bits at the beginning and end of each character. It is also referred to as start-stop transmission. Asynchronous transmission does not require the transmitters and receivers to have clocks to stay in synch.
