What is Demand Paging and Page Replacement Explained about?
Demand paging brings pages into memory only when they are needed, reducing memory usage. It combines features of paging and overlaying. When a process references a page not in memory, a page fault occurs and the OS loads the page from disk. Hardware support includes page tables with valid/invalid bits and secondary storage. The OS uses a page replacement algorithm like FIFO to select a victim page when it needs to load a new page from disk.
