The Process Management of the Operating System

The operating system can engage in something called paging, whereby it basically grabs a bunch of data that's saved on ram and moves it over to the hard drive. It doesn't matter if two processes have the same address in their virtual memory, because those are separate from each other. As long as the physical memory uniquely contains is unuquely applocated to one particular process at a given time. S i just wanted to mention that's how memory is managed. The job of the operating system is to keep track of all the currently running processes and what their memory mappings are and where they're stored.
