What is the difference between the Default dispatcher and the IO dispatcher in Kotlin Coroutine?

Default is used for tasks that require intensive computation (CPU-bound), such as processing large lists, parsing JSON. It is limited by the number of CPU cores.

IO is intended for input/output operations (IO-bound), such as network requests, working with files, databases. It can use more threads than the number of cores because IO operations often block the current thread, allowing other tasks to execute.
