Dispatchers.Default - Uses a thread pool equivalent to number of CPU cores. Should be used for CPU bound workload.
Dispatchers.IO - Uses a pool of 64 threads. Ideal for IO bound workload, where the thread is usually waiting; maybe for network request or disk read/write.
Dispatchers.Main (Android only): Uses main thread to execute the coroutines. Ideal for updating UI elements.






GlobalScope.launch(Dispatchers.IO): Launches a top-level coroutine on Dispatchers.IO. Coroutine is unbound and keeps running until finished or cancelled. Often discouraged since programmer has to maintain a reference to join() or cancel().
