Characteristics of Paging and Segmentation
nMemory references are dynamically translated into physical addresses at run time
ua process may be swapped in and out of main  memory such that it occupies different regions
nA process may be broken up into pieces (pages or segments) that do not need to be located contiguously in main memory
nHence: all pieces of a process do not need to be loaded in main memory during execution
ucomputation may proceed for some time if the next instruction to be fetch (or the next data to be accessed) is in a piece located in main memory
