Explain what is meant by Dispatcher in the context of programming or system architecture.

In programming or system architecture, a Dispatcher is a component responsible for distributing tasks, events, or messages among different handlers or threads.

In the context of Android, for example, a Dispatcher is often associated with thread management and task queues. It accepts tasks and directs them to execute on the appropriate thread (such as the main UI thread or a background thread).

For example, in Kotlin Coroutines, there is a CoroutineDispatcher that determines which thread a coroutine will run on — whether on the main thread, a thread pool, or another.

Thus, the Dispatcher ensures efficient management of execution and load distribution within an application.
