What types of tasks related to work execution exist?

In Android, tasks related to performing work can be divided into several types:

• Main thread (UI thread): responsible for updating the interface and handling user events.
• Background tasks: executed outside the main thread to avoid blocking the UI. For example, data loading, network requests.
• Deferred tasks: tasks that need to be executed later or periodically, for example, using WorkManager.
• Asynchronous tasks: executed in parallel, often using AsyncTask (deprecated), Coroutines, or RxJava.

Example of a background task using Kotlin Coroutines:

import kotlinx.coroutines.*

fun loadData() {
    GlobalScope.launch(Dispatchers.IO) {
        val data = fetchDataFromNetwork()
        withContext(Dispatchers.Main) {
            updateUI(data)
        }
    }
}
