Swapping in the memory-management context: there IS a difference between "Paging" and "Swapping", namely, there's also "Segment-swapping".

Segment swapping swaps segments to and from the hard disk, whereas "page-swapping" uses fixed-length pages. Main differences are that page-swapping is most commonly used these days, since segment-based swapping is more complex to implement, due to its variable-size segments. It generates less segment-faults than paging, and is therefore (theoretically) more performant. OS/2 supports segment swapping, see for example [1]:

Segment Swapping The OS/2 subsystem uses the Windows NT paging mechanism; no segment swapping is performed. Segment swapping is inferior to paging and exists in OS/2 only to support the 80286 processor, which is not supported for Windows NT.

I think there should be a split up between paging, swapping and segments. —Preceding unsigned comment added by 84.196.239.127 (talk) 16:51, 30 December 2008 (UTC)[reply]
