swap vs paging?

Hi

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

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.
