Lightweight Thread

Threads are typically compared in terms of processing time. For example, a lightweight thread is a thread that takes less processing time, whereas a heavyweight thread is a thread that requires more processing time. Thread processing time is also contingent on the language used for thread implementation. For example, it may be more efficient to use C# to implement a program containing multiple threads.

Modern operating systems, like Mac, allow for more than a single thread in the same address space, reducing switching time between threads. However, this does not make use of multithreading benefits.
