WebWith the help of virtual memory, you can easily fit many large programs into smaller programs. In a virtual memory environment the minimum number of page frames that must be allocated to a running process is . As more processes should be maintained in the main memory which leads to the effective utilization of the CPU. During the process creation, virtual memory allows: copy-on-write and Memory-mapped files. 2 method through which programs can be executed that requires space larger than that available in physical memory by using disk memory as a backing store for main memory. The questions asked in this NET practice paper are from various previous year papers. This is where virtual memory in computer architecture comes in. The CPU first tries to find the requested page in the main memory and if it is found then it will be provided immediately otherwise an interrupt is generated that indicates memory access fault. To free user programs from the need to carry out storage allocation and to permit efficient sharing of the available memory space among different users. Working set model for page replacement is based on the assumption of In the common language runtime (CLR), the garbage collector (GC) serves as an automatic memory manager. d) demand paging, 3. process is trash Page, it allows us to have memory protection because each virtual address space can be accessed just main Is implemented two if there are three different ways of doing this.!
