to a program while it is sheduled, here i mean how it determines the

all help is appreciated

Your question doesn't really make sense. First, it's not clear whether
it's about physical memory or virtual memory. Second, it implies that
memory is allocated when a process is scheduled, which is not the
case. Memory is allocated when the process requests it.

What are you trying to ask? It's not clear.
