<architecture> Not synchronised by a shared signal such as
clock or semaphore, proceeding independently.
Opposite: synchronous.
1. <operating system> A process in a multitasking system
whose execution can proceed independently, "in the
background". Other processes may be started before the
asynchronous process has finished.
2. <communications> A communications system in which data
transmission may start at any time and is indicated by a
start bit, e.g. EIA-232. A data byte (or other element
defined by the protocol) ends with a stop bit. A
continuous marking condition (identical to stop bits but not
quantized in time), is then maintained until data resumes.
