1.	How does paging work in the memory?
Answer» Whenever data is requested from the memory, the CPU first HITS the primary memory, i.e RAM, and checks if the requested data is present on that page in the memory. If it is not present, then the CPU performs paging on secondary memory, i.e READS data from hard disk in equal blocks of MEMORIES called pages. During paging, a frame constitutes a single page of physical memory and it NEED not be physically contiguous. This ensures faster memory access and ensures data is fetched faster from secondary memory.
