Mapping Virtual Addresses to Physical Addresses :In Contiguous memory allocation mapping from virtual addresses to physical addresses is not a difficult task, because if we take a process from secondary memory and copy it to the main memory, the addresses will be stored in a contiguous manner, so if we know the base address of the process, we can find out the next addresses. Determine the directory base of the address by using the !process extension: Determine the page frame number of the directory base. Most software vendors have a documented method for performing this.
