Given a virtual memory of size 4 GiB, physical memory of size 1 GiB, and page size equal to 256 KiB.  How many bits are used to specify a virtual page number?

Suppose a computer system uses 16-bit addresses for both its virtual and physical addresses. In addition, assume each page (and frame) has size 256 bytes. How many bits are used for the page number? How many bits are used for the offset? 8 bits each. With this system, what’s the maximum number of pages that a process can have? 256 Suppose that each entry in the page table comprises 4 bytes (including the frame number, the valid bit, and miscellaneous “bookkeeping bits”). An OS uses an array to store the page table. What is the size of the page table? 1024 Bytes Furthermore, suppose the first 6 pages of a process map to frames 222 to 227 (as decimal numbers), and the last 5 pages of the process map to frames 1 to 5 (also decimal numbers). All other pages are invalid. Draw the page table, including the valid bit and the frame number. DONE Translate the following virtual addresses to physical addresses, and show how you obtain the answers. (Hint: You do not need to convert…

Consider a logical address space of 1K pages with a 4KB page size, mapped onto a physical memory of 128 frames. 1. How many bits are required in the logical address? Logical bits- 2. How many bits are required in the physical address? Physical bis-

What is the physical address of the following picture:

Given a virtual memory of size 4 GiB, physical memory of size 512 KiB, and page size equal to 4 KiB.  How many bits are used to specify a physical page number?

Giventhe following assignment of some program’s virtual pages to physical pages in a system with 4 KiB byte pages, what physical memory address corresponds to virtual address 20000? (All values are given in decimal.)

Given that the main memory size is 32KB, the page size is 64B, the word size is 1B, and n-level paging is applied. What is the value of n?

16-bit virtual addresses

Write the binary translation of the logical address 0001010010111010 to physical address, under the following hypothetical memory management schemes, A paging system with a 256 pages, The corresponding frame number is 00000101
