Assuming the following page table, answer the questions below: a) How many bits are in a virtual address? b) How many bits are in a physical address? c) What physical address corresponds to the following virtual addresses (if the address causes a page fault, simply indicate this is the case)? a byte-addressable virtual address memory Frame # Valid Bit i) 0×0B ii) ОхВА iii) 0×1C iv) 0×3A v) 0x34 Page # 3 1 1 1 1 2 4 1 5 7 2
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-
Consider a logical address space of 1024 pages with 2 KB page size, mapped onto a physical memory of 128 frames. How many bits are required in the logical address? Select one: a.512 bits b.10 bits c.18 bits d.21 bits
We use the concept "paging" to map logical address to physical address. If the process size is 9216 bytes, the page size is 2048 bytes, how many frames should be allocated to this process? Do we have fragment? If so, please indicate the size of fragment?
How many distinct page kinds does CSS support? the capability of caches to increase performance via the application of examples of "spatial locality" and "temporal locality." Could you perhaps clarify on the advantages that caches get from the two events that have just occurred?

There are several parameters that impact the overall size of the page table. Listed below are key page table parameters. Virtual Address Size Page Table Entry Size Page Size 8 KiB 32 bits 4 bytes (a) Given the parameters shown above, calculate the total page table size for a system running 5 applications that utilize half of the memory available.
Given a modern 64-bit architecture with 6-bytes used for each page pointer, 1 MB pages, and 16 GB installed memory: a) How much memory can be addressed by the paging solution? b) How large must each page table be? c) Suggest a better solution, include a diagram to represent your memory hierarchy.
Operating systems that allow memory-mapped files always require files to be mapped at page boundaries. For example, with 4-KB pages, a file can be mapped in starting at virtual address 4096, but not starting at virtual address 5000. Why?
Consider the following page address stream: 2 4 2 4 1 2 5 1 3 3 1 Using the Least Recently Used algorithm on a machine with 4 frames, which page address will cause the first fault? a) 1 b) No fault occurs c) 2 d) 3 e) 5 f) 4
Suppose we have a 32-bit virtual address space and a 4KB page size. What is the number of pages required to support an 8MB working set?
