A refinement of paging in which it is not necessary to load in the entire contents of the text and data segments of a program from disk when the process is started. Instead, pages are brought into memory as they are accessed. Demand paging is enabled by hardware features of the 80386 and 80486 processors that are supported by the operating system.
