Final answer:
On-demand paging does not require all of a process's pages to be swapped in or out at a given time.
Step-by-step explanation:
False
On-demand paging does not require all of a process's pages to be swapped in or out at a given time. On-demand paging is a memory management technique that allows the operating system to bring in individual pages of a process into memory only when they are needed.
For example, when a process accesses a page that is not currently in memory, a page fault occurs and the operating system fetches the required page from the disk into memory. This approach reduces memory wastage and improves overall system performance.
