Multithreading and asynchronous programming, if properly implemented, improve the performance of an application. Multithreading refers to the practice of executing multiple threads at the same time to execute multiple operations or tasks in parallel. There could be one main thread and several background threads, usually known as worker threads, running in parallel at the same time, executing multiple tasks concurrently, whereas both synchronous and asynchronous operations can run on a single-threaded or a multithreaded environment.
In a single-threaded synchronous operation, there is only one thread that performs all the tasks in a defined sequence, and it executes them one after the other. In a single-threaded asynchronous operation, there is only one thread that executes the tasks, but it allocates a time slice in which to run each...
