asynchronous

[ā′siŋ·krə·nəs]
(computer science)
Operating at a speed determined by the circuit functions rather than by timing signals.
(physics)
Not synchronous.

asynchronous

(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.

asynchronous

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.

Among the principles and effective practices included in this statement, the CCCC Committee on Best Practices for Online Writing Instruction (OWI) maintains that online students should receive writing support that parallels the instructional format for that course, including asynchronous tutoring, and that instructors and tutors should be committed to ongoing research related to supporting online writing students (Principles 13 and 15).
