Asynchronous operation

In telecommunication
s, asynchronous operation or asynchronous working is where a sequence
of operations
is executed such that the operations are executed out of time
coincidence with any event
. It can also be an operation that occurs without a regular or predictable time relationship to a specified event; e.g., the calling of an error
diagnostic routine
that may receive control at any time during the execution of a computer program

Telecommunication
Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded...
s, asynchronous operation or asynchronous working is where a sequence
Sequence
In mathematics, a sequence is an ordered list of objects . Like a set, it contains members , and the number of terms is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence...

Operation (mathematics)
The general operation as explained on this page should not be confused with the more specific operators on vector spaces. For a notion in elementary mathematics, see arithmetic operation....
is executed such that the operations are executed out of time
Time
Time is a part of the measuring system used to sequence events, to compare the durations of events and the intervals between them, and to quantify rates of change such as the motions of objects....

Event-driven programming
In computer programming, event-driven programming or event-based programming is a programming paradigm in which the flow of the program is determined by events—i.e., sensor outputs or user actions or messages from other programs or threads.Event-driven programming can also be defined as an...
. It can also be an operation that occurs without a regular or predictable time relationship to a specified event; e.g., the calling of an error
Error
The word error entails different meanings and usages relative to how it is conceptually applied. The concrete meaning of the Latin word "error" is "wandering" or "straying". Unlike an illusion, an error or a mistake can sometimes be dispelled through knowledge...

Routine
Routine may refer to:*Subroutine in computer science*Choreographed routine, orchestrated dance involving several performers*Comedy routine, comedic act or part of an act*Visual routine, visual cognitive means of extracting information from a scene...

Computer program
A computer program is a sequence of instructions written to perform a specified task with a computer. A computer requires programs to function, typically executing the program's instructions in a central processor. The program has an executable form that the computer can use directly to execute...
