    Default swap vs paging?

    Hi

    What is the difference between swap memory and paging. Both are same or different.

    Default Re: swap vs paging?

    Swapping refers to copying the entire process address space, or at any rate, the non-shareable-text data segment, out to the swap device, or back, in one go (typically disk).

    Paging is also usually associated with per-page memory attributes (no access, read-only, read-write, no execute, executable), and various virtual memory management tricks like demand-zero-filled pages, copy-on-write pages, and so forth.
