Answer B. types. False 10) Virtual Memory can be implemented without page replacement. Hence the correct answer is Demand paging. Figure 9.1 shows the general layout of virtual memory, which can be much larger than physical memory: Figure 9.1 - Diagram showing virtual memory that is larger than physical memory. Paged virtual memory is the most often used implementation. It transfers processes between the computer's RAM and hard disk by copying any files from the computer's RAM that aren't currently in use and moving them to the hard disk. Q 1. By moving unused files to the hard disk, a computer frees up space in its RAM to perform current tasks . Question Virtual memory can be implemented with ____________. Computer Networks. In this scheme, User can load the bigger size processes than the available main memory by having the illusion that the memory is available to load the process. We all know that a process is divided into various pages and these pages are used during the execution of the process.
