When should you use multithreading? And would multi threading be beneficial if the different threads execute mutually independent tasks?

Question

This were the only two questions I couldn\'t answer in the interview I got rejected from last night.

Answer 1

When should you use multithreading?

Multithreading is a process of executing multiple threads simultaneously. You should use multithreading when you can perform multiple operations together so that it can save time.

Would multithreading be beneficial if the different threads execute mutually independent tasks?

it is usually yes. Multithreading would usually be beneficial if the different threads execute mutually independent tasks so that it doesn't affect other threads if exception occur in a single thread.
