Aplication Layer Mcqs; Ethernet Mcqs; LAN Standards Mcqs Logical Address or Virtual Address (represented in bits): An address generated by the CPU. But with time, when there is a need for other pages, then the CPU will find that page from the secondary memory and load that page in the main memory. The addresses a program may use to reference memory are disnguished from the addresses the memory system uses to idenfy physical storage sites, and program-generated addresses are translated automa . First, it allows us to extend the use of physical memory by using disk. Virtual memory can be implemented using two common mechanisms called demand segmentation and demand paging. 9) Virtual Memory cannot be implemented without demand paging. The questions asked in this NET practice paper are from various previous year papers. ____________ is one or more physically contiguous pages. The threads issue virtual addresses when reading and writing to memory (see Figure 5.16).The memory manager translates each virtual address issued by the processor into a physical address, a bus address of a location in memory or a register on a controller of a device. If there is some request for the pages present in the physical memory, then it is directly served otherwise if the page is not present in the physical memory then it is called a page fault and whenever page fault occurs, then we load the demanded page in the memory and this process is known as Demand Paging. Answer B. Q. Which one of the following statements is not correct regarding the usage of virtual memory? a) processes What is Virtual Memory and how is it implemented? 2. Segmentation. As a result, it is also known as a lazy swapper since it only swaps pages when the CPU requires it. c) Segmentation Ideally, the data needed to run applications is stored in RAM, where they can be accessed quickly by the CPU.
