Asynchronous communication

In telecommunications, asynchronous communication is transmission of data, generally without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream. ^[1]

Anisochronous

In telecommunication, the term anisochronous refers to a periodic signal, pertaining to transmission in which the time interval separating any two corresponding transitions is not necessarily related to the time interval separating any other two transitions. Asynchronous communication and anisochronous are synchronization.

Circuit switching

Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate.

See Asynchronous communication and Circuit switching

Clock generator

A clock generator is an electronic oscillator that produces a clock signal for use in synchronizing a circuit's operation.

See Asynchronous communication and Clock generator

Clock signal

In electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat) is an electronic logic signal (voltage or current) which oscillates between a high and a low state at a constant frequency and is used like a metronome to synchronize actions of digital circuits. Asynchronous communication and clock signal are synchronization.

Frame (networking)

A frame is a digital data transmission unit in computer networking and telecommunication.

Frame synchronization

In telecommunication, frame synchronization or framing is the process by which, while receiving a stream of fixed-length frames, the receiver identifies the frame boundaries, permitting the data bits within the frame to be extracted for decoding or retransmission. Asynchronous communication and frame synchronization are synchronization.

In coding theory, especially in telecommunications, a self-synchronizing code is a uniquely decodable code in which the symbol stream formed by a portion of one code word, or by the overlapped portion of any two adjacent code words, is not a valid code word.
