What thread management mechanisms are implemented in Dispatcher when using coroutines?

In Kotlin Coroutines, Dispatcher manages which thread or thread pool will execute the coroutine. The main mechanisms of thread management in Dispatcher are:

• Dispatching — selecting the appropriate thread or thread pool for executing the coroutine.
• Thread pool — for example, Dispatchers.Default uses a shared thread pool optimized for CPU-intensive tasks.
• Single-threaded dispatchers — for example, Dispatchers.Main for the UI thread in Android.
• Deferred execution and context switching — coroutines can switch between dispatchers, allowing efficient thread management.

Thus, Dispatcher abstracts thread management, enabling coroutines to run in the desired context without manual thread creation and management.
