process - Are processes executed on operating system -


i saw question somewhere

four processes p1, p2, p3, p4 - each have sizes 1gb, 1.2gb, 2gb, 1gb. , each processes executed time sharing fashion. executed on operating system.

i think answer should no,they not executed on operating system because os process , running in parallel these processes.there switching between processes time time of dispatcher.

but getting doubt answer can yes because uses every process uses memory managed theb operating system .

please me figure out right answer question..

this depends entirely on os in question.

as starting processes (and possibly consisting of processes), operating system provides services processes run on it, such memory management, file systems, communications , on.

in context, these processes can said running on top of os. in other words, processes of little use unless communicate outside of themselves.

in event, dispatcher (or scheduler) tends integral part of os having processes scheduled means you're running on top of os.

modern operating systems provide paging of memory means can use lot more virtual memory there physical memory - os responsible handling requests memory has been paged out.
