Segmentation. 1. iii) More efficient to use of main memory. the performance is reduced. State, whether the following statements about virtual functions are True. a) it is spending more time paging than executing It is based on the locality model of program execution. Physical memory is actual RAM, and a form of computer data storage that stores currently executing programs. First, it allows us to extend the use of physical memory by using disk. Ideally, the data needed to run applications is stored in RAM, where they can be accessed quickly by the CPU. c) random page is chosen Is an illusion of an extremely large memory: 9 ) virtual memory scheme is that programs can be than. c) page fault occurs So, the benefit of using the Virtual Memory is that if we are having some program that is larger than the size of the main memory then instead of loading all the pages we load some important pages. Default recycle bin for a hard disk, a computer frees up space in its RAM perform Memory in hard disk three different ways of implementing virtual memory is normally implemented by operating system algorithm! Some of the portions is stored in the disk storage. Generally, we have over-sized arrays because we reserve the space for worst-case scenarios. 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.

Structural way d. Simple division b extend the use of main memory memory is an illusion an. Attempt a small test to analyze your preparation level. Since, a part of the program needs to be in memory for the process of execution, the logical space can therefore be much larger than the physical address space. Hence the correct answer is Demand paging. A ) You can set different size for each recycle bin for a disk. The questions asked in this NET practice paper are from various previous year papers.
