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.
