OPERATING SYSTEMConsider a simple paging system with the following parameters: * 2^32 bytes of physical memory * Page size of 2^10 bytes * 2^16 pages of logical address space (i) How many bits are in a logical address? (ii) How many bytes are in a frame? (iii) How many bits in the physical address specify the frame? (iv) How many entries are in the page table?20227mOperating SystemExplain the Address Translation mechanism in Paging. Why is the page size normally some power of two?20247mOPERATING SYSTEMThe address loaded into the memory address register of the memory is referred to as (i) Physical address (ii) IP address (iii) Port address (iv) Logical address20242mCOMPUTER ORGANIZATION & ARCHITECTUREA virtual memory system has an address space of 8k words, memory space of 4k words and page & block size of 1k words. The following page reference changes occur during a given time interval: 4, 2, 0, 1, 2, 6, 1, 4, 0, 1, 0, 2, 3, 5, 7 Determine the four pages that are resident in main memory after each page reference change if the replacement algorithm used is - (i) FIFO - (ii) LRU.201614m
