A type of transmission in which information is sent at random, at any speed with no routing information.

successive data appears in a data stream at arbirary times - however bits making up the data are clocked (asynch between data sync within data)

A set of rules for exchanging information between computers in a network environment using asynchronous lines.

A protocol designed for unsynchronised (non-clocked) events, such as the bursty transmission of ASCII characters.

A type of transmission where information is sent at any speed and at random with no routing information.

The movement of information from one device to another. Information is sent in digital format one character at a time, preceded by a start bit and followed by a stop bit. The sending device waits for a reply that the information has been received. After receiving the reply the next batch of information can be sent. Commonly referred to single stream, one way at a one time communication.
