How does an Operating system works surrounded by single processor?

operating sys is binnery codes of appliance language from software discourse, Processor is giving binery signals.
I'm guessing you mean surrounded by terms of program execution, to administer the illusion that several processes are running at impossible to tell apart time.



The task scheduler program have a software interrupt triggered on the processor to go stale every so often contained by little slices of time. When this interrupt is fired, the task scheduler wake up and selects a process to generate. It does this based on how much CPU the process have been using, the process' priority, and the time since the process be last run. This can happen hundreds of times per second.
First sour, an operating system Has nothing to do near the processor.
