Asynchronous timing refers to a method of scheduling events or processes that do not occur simultaneously. In this system, tasks can start and finish at different times, allowing for more flexibility and efficiency. This is commonly used in computer programming, where functions can run independently without waiting for others to complete. In contrast to synchronous timing, where tasks are executed in a fixed sequence, asynchronous timing enables better resource utilization. For example, in web development, JavaScript often uses asynchronous calls to fetch data from a server, allowing the user interface to remain responsive while waiting for the data to load.
