MultiThread on Single Core Processor (CPU)

Is it possible to run multi-threads on a single-core processor? Best Regards...

Yes, you can spawn multiple threads on single core system. Processor with swap between threads based on priority and that will give an illusion of multithreaded processing.

Yes. Multitasking - Win32 apps | Microsoft Docs[^]

Yes. Under Windows, it's been that way since the dawn of Windows 2.1, back in, what, 1988-ish? Today, you can just open Task Manager, click on the Performance tab, and the CPU tab on the left. See the "Threads" number? See the "Core" and "Logical processors" numbers? How else are you going to get thousands of threads running on so few processors?

No one I know had a quad-core i386 :D Still, didn't want to be that blunt.

:laugh: Peasant! I can't remember the first time I laid hands on a multiple CPU machine, but it wasn't until the mid 90's at a minimum. Go Windows NT 3.x!

See [OS/360 and successors \- Wikipedia](https://en.wikipedia.org/wiki/OS/360\_and\_successors#MVT). There were processors and operating systems half a century ago that supported multiple tasks (threads). The idea was that many things, especially I/O, took time and if only one task executes then the processor is idle for a long period of time. Back then disk drives and tape drives were very slow.
