What is the difference between Dispatchers.Default and Dispatchers.IO in Kotlin Coroutines?

In Kotlin Coroutines, Dispatchers.Default and Dispatchers.IO are intended for different types of tasks:

• Dispatchers.Default: used for CPU-intensive operations, such as computations and data processing. It uses a thread pool whose size depends on the number of available processor cores.

• Dispatchers.IO: optimized for input/output operations (reading/writing files, network requests, working with databases). It uses an extended thread pool that allows running more threads than CPU cores to avoid blocking coroutines while waiting for IO.

Example:

// CPU-intensive task
withContext(Dispatchers.Default) {
    // complex calculations
}

// IO-intensive task
withContext(Dispatchers.IO) {
    // reading a file or network request
}
