Asynchronous

Asynchrony, in the general meaning, is the state of not being synchronized.

• Asynchronous learning, a student-centered teaching method that uses online learning resources to facilitate information sharing outside the constraints of time and place among a network of people
• Collaborative editing systems
• Asynchronous circuit, is a sequential digital logic circuit which is not governed by a clock circuit or global clock signal
• Asynchronous system, has no global clock: instead, it operates under distributed control, with concurrent hardware components communicating and synchronizing on channels
• Asynchronous communication, transmission of data without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream
• Asynchronous serial communication, describes an asynchronous, serial transmission protocol in which a start signal is sent prior to each byte, character or code word and a stop signal is sent after each code word
• Asynchronous cellular automaton, able to update individual cells independently, in such a way that the new state of a cell affects the calculation of states in neighbouring cells
• Asynchronous Transfer Mode, according to the ATM Forum, "a telecommunications concept defined by ANSI and ITU (formerly CCITT) standards for carriage of a complete range of user traffic, including voice, data, and video signals," and is designed to unify telecommunication and computer networks
• Asynchrony (computing)
• Asynchronous motor, a variety of electric motor where the electromagnetic field turns with a different (higher) speed than the rotor; the difference is called slip

L’asynchronisme désigne le caractère de ce qui ne se passe pas à la même vitesse, que ce soit dans le temps ou dans la vitesse proprement dite, par opposition à un phénomène synchrone.

Asynkron innebär att ett skeende interagerar med ett annat skeende, men helt oberoende av det andra skeendet. Motsatsen är synkron, då skeenderna koordinerar med varandra i tiden.
