In electronics, “asynchronous” refers to a method in which synchronization is not required in data transmission or signal processing.
This term is often used to describe how an electronic component or system behaves.
Asynchronous transmission or processing does not use a fixed clock or timing signal between sender and receiver.
Instead, data transmission operates according to start and end points, and data bits are transmitted independently.
This is useful when the rate or timing of data is not constant, or when asynchronous communication between multiple senders and receivers is required.
Asynchronous communication methods in electronic components are related to UART (Universal Asynchronous Receiver Transmitter) or Asynchronous Serial Communication.
UART transmits data bits asynchronously in serial communication, and uses start and stop bits to indicate the start and end of data frames.
It is often used for data transmission or communication between a computer and a peripheral device.
Asynchronous processing can also be used in computer systems.
For example, asynchronous event handling means that processors process and respond to events independently.
This is useful in multi-threaded environments or event-driven systems.
Asynchronous electronics can efficiently transmit or process data, reduce system complexity and increase flexibility.
