    Pages are blocks of RAM, say 4K bytes in size, that are mapped from physical memory to logical memory by the memory manager hardware. Unused pages can be 'paged out' so that RAM is used efficiently. Pages are also the way in which the OS uses to prevent one process interfering with the memory of another process - fundamental to security.

    The job of the operating system includes managing page mapping.
