asynchronous - Computer Definition
From Latin and Greek origins, asynchronous translates as not together with time. Referring to signals or events that bear no relationship to timing and, therefore, can be considered occurring at random instants and, for recurring events, at random intervals. See also asynchronous transmission and synchronous.
Asynchronous refers to transmission of data through networks, and the transmission is not governed by specific timing requirements on the transmission end. Asynchronous transmission is used on a byte level as well as on the level of entire messages.
See Also: Bytes.
Events that are not synchronized or coordinated in time. All the following are asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end. Storing and forwarding messages. Starting the next operation before the current one is completed. Contrast with synchronous.
