Selgitage paralleelsete arvutuste kontseptsiooni ja selle erinevust järjestikustest protsessidest

Parallel calculations involve executing multiple computational tasks simultaneously, using multiple processors or cores. This allows for speeding up the processing of large volumes of data or complex tasks.

Unlike sequential processes, where tasks are executed one after another, parallel calculations distribute the work among threads or processes that operate concurrently.

For example, in C#, you can use Task to start several operations in parallel:

Task task1 = Task.Run(() => DoWork1());
Task task2 = Task.Run(() => DoWork2());
Task.WaitAll(task1, task2);

Here, DoWork1 and DoWork2 are executed simultaneously, which can significantly reduce the total execution time compared to sequential calls.
