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 serves two purposes. First, it allows us to extend the use of physical memory by using disk. Second, it allows us to have memory protection, because each virtual address is translated to a physical address.
Detailed explanation-3: -So virtual memory is used that provides a larger amount of space to the process. Some of the portions are stored in the disk storage. It allows us to extend the use of physical memory by using hard disk space. It allows us to have memory protection because each virtual address is translated into physical memory.
Detailed explanation-4: -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-5: -Disadvantages of Virtual Memory Offers lesser hard drive space for your use. It reduces system stability. It allows larger applications to run in systems that don’t offer enough physical RAM alone to run them. It doesn’t offer the same performance as RAM.
