What Does Multithreading Mean?
Multithreading is a CPU (central processing unit) feature that allows two or more instruction threads to execute independently while sharing the same process resources. A thread is a self-contained sequence of instructions that can execute in parallel with other threads that are part of the same root process.
Techopedia Explains Multithreading
The 32- and 64-bit versions of Windows use pre-emptive multithreading in which the available processor time is shared. All threads get an equal time slice and are serviced in a queue-based model. During thread switching, the context of a pre-empted thread is stored and reloaded in the next thread in the queue. This takes so little time, that the running threads seem to execute in parallel.
