    Concept of Virtual Storage

    Q17. Explain the concept of virtual storage. Ans. A program can be stored at non contiguous locations, suppose even if we use all available free memory areas still the program cannot be loaded into the main storage because the total free memory is still less than the size of the program. To solve such a problem, we require a technique with which a program can still be executed even if all of it is not loaded in the memory. Virtual storage helps one perform such an execution. Two main approaches to virtual storage are program-paging program-segmentation

    Functions Performed By An Operating System As Memory Manager

    Q16. Explain briefly the functions performed by an operating system as memory manager? Ans. In the working of a modern computer system, memory plays a central role. Both CPU and Input/output system interact with memory. Memory is a large array of words or bytes, each with its own address. The CPU reads from and writes to specific memory addresses.     A program must be assigned some memory area and loaded into memory in order to be executed. As the program executes, it accesses program instructions and data from memory by generating addresses of the allocated memory.

Multiprogramming, undoubtedly, improves the overall efficiency of the computer system by getting more work done in less time as the CPU may be shared among a number of active programs which are present in the memory at the same time. While CPU is executing a job, it has to wait for the job; if the job requires certain Input/output operation, the CPU waits for the Input/output operation to get over…
