What is the role of the Dispatcher component in the system architecture?

In system architecture, especially in the context of Android and multithreaded programming, the Dispatcher component is responsible for managing threads and distributing tasks among them. It controls which thread will execute a particular operation, ensuring proper context switching and preventing UI thread blocking.

For example, in Kotlin Coroutines, the Dispatcher determines where exactly the coroutine will run: on the main thread (UI), on a background thread for input/output, or in a thread pool for computations. This allows for efficient resource management and improved application responsiveness.
