Detailed explanation-1: -The advantages to using virtual memory include: It can handle twice as many addresses as main memory. It enables more applications to be used at once. It frees applications from managing shared memory and saves users from having to add memory modules when RAM space runs out.
Detailed explanation-2: -Virtual memory is a technique that allows the execution of processes that are not completely in memory. One major advantage of this scheme is that programs can be larger than physical memory.
Detailed explanation-3: -Virtual memory has multiple advantages for computer systems: More applications can run at the same time on the same system. Larger applications can run on systems that don’t have enough physical RAM alone to run them. Increasing memory with virtual memory is less costly than buying more RAM.
Detailed explanation-4: -Demand paging allows the execution of programs large than the size of physical memory.
