Webpaging; segmentation; Paging splits the address space into equal sized units called pages. While segmentation splits the memory into unequal units that may have sizes more meaningful or appropriate to the program. These two ideas can be combined.

It is just like the Paging technique except the fact that in segmentation, the segments are of variable length but, in Paging, the pages are of fixed size. In segmentation, the memory is split into variable-length parts. Each part is known as segments.
