File Page
In computer operating systems, paging is one of the memory-management schemes by which a computer can store and retrieve data from secondary storage for use in main memory. In the paging memory-management scheme, the operating system retrieves data from secondary storage in same-size blocks called pages. The main advantage of paging over memory segmentation is that it allows the physical address space of a process to be noncontiguous. Before paging came into use, systems had to fit whole programs into storage contiguously, which caused various storage and fragmentation problems.
Paging is an important part of virtual memory implementation in most contemporary general-purpose operating systems, allowing them to use disk storage for data that does not fit into physical random-access memory (RAM).

Famous quotes containing the words file and/or page:
“While waiting to get married, several forms of employment were acceptable. Teaching kindergarten was for those girls who stayed in school four years. The rest were secretaries, typists, file clerks, or receptionists in insurance firms or banks, preferably those owned or run by the family, but respectable enough if the boss was an upstanding Christian member of the community.”
—Barbara Howar (b. 1934)
“When you’ve been blind as long as I have, you learn to see through your senses. I can’t explain it exactly, but you get a feeling about people when you meet them. You see a picture of them in your mind. Not just what they look like, but what they really are. You see them much more clearly than you do with your eyes. Maybe that’s why they say looks are deceptive.”
—George Bricker. Jean Yarbrough. Helen Page (Jane Adams)
