Asynchronous and Synchronous Transmission

Asynchronous and synchronous communication refers to methods by which signals are transferred in computing technology. These signals allow computers to transfer data between components within the computer or between the computer and an external network. Most actions and operations that take place in computers are carefully controlled and occur at specific times and intervals. Actions that are measured against a time reference, or a clock signal, are referred to as synchronous actions. Actions that are prompted as a response to another signal, typically not governed by a clock signal, are referred to as asynchronous signals.

Typical examples of synchronous signals include the transfer and retrieval of address information within a computer via the use of an address bus. For example, when a processor places an address on the address bus, it will hold it there for a specific period of time. Within...
