Mis vahe on Dispatchers.Default ja Dispatchers.IO vahel Kotlin Coroutines kontekstis?

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

• Dispatchers.Default: used for CPU-intensive operations, such as calculations 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 the number of CPU cores, so coroutines are not blocked 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
}
