Page Size in Operating System:
Definition and Explanation:
Page size is a hardware design issue. Small pages reduce the amount of internal fragmentation. Large pages reduce the size of the page table. In general, small pages have better locality than large pages. As a result, page faults tend to be less frequent for systems with small pages. As page size approaches program size, this relationship is reversed. Page fault rate is partly a function of page size. It is partly a function of the number of pages allocated to a process.
