Paging avoids fragmentation

http://www.cs.iit.edu/~cs561/cs351/memory_management_FS_sched/index_mm_04.html WebThe basic difference between paging and swapping is that paging avoids external fragmentation by allowing the physical address space of a process to be noncontiguous whereas, swapping allows multiprogramming. Paging would transfer pages of a process back and forth between main memory, and secondary memory hence paging is flexible.
