Improving Program Structure

Many programs are more efficiently structured as multiple independent or semi-independent units of execution instead of as a single, monolithic thread. For example, a non-threaded program that performs many different tasks might need to devote much of its code just to coordinating the tasks. When the tasks are programmed as threads, the code can be simplified. Multithreaded programs, especially programs that provide service to multiple concurrent users, can be more adaptive to variations in user demands than single-threaded programs.
