GitHub - omarmoh26/Page-Replacement-Simulator: In an operating system that uses paging for memory management, a page replacement algorithm is needed to decide which page needs to be replaced when new page comes in. If no frame is free, OS finds a page (victim frame) that is not currently being used and free it. OS frees a frame by writing its contents to swap space (virtual memory) and changing the page table (and all other tables) to indicate that the page is no longer in memory. Another definition, page fault, is defined as accessing a page that is mapped into the logical address space, but not loaded in physical memory
