- Remote Method Incocation (RMI) is a mechanism that allows one to invoke a method on an object that exists in another address space. The other address space could be on the same machine or a different one. Briefly describe the following with respect to RMI software architecture: Proxy. Dispatcher. Skeleton.What physical address corresponds to the following virtual addresses? (If the address causes a page fault, simply indicate this is the case.)1. 0x02. 0x443. 0xC24. 0x80Which of the following term is used to monitor the connection between a page of a process to a frame in physical memory? Choose an answer A Page offset B Page fault C Frame offset D Page map table
- A certain computer provides its users with a virtual-memory space of 232 bytes. The computer has 218 bytes of physical memory. The virtual memory is implemented by paging, and the page size is 4096 bytes. A user process generates the virtual address 11123456. 5.3 Under what circumstances do page faults occur? Describe the actions taken by the operating system when a page fault occurs.Imagine that to save space, the TLB drops the Read/Write and User/Supervisor protection bits. The page table still has the protection bits. However, when moving from user mode to kernel mode (or vice versa), the TLB is flushed. i) Could a process access memory belonging to another process? How? ii) Could a process access memory belonging to the kernel? How? iii) What problem could arise if a process can write memory it is normally supposed to only read?What is Translation Look-Aside Buffer used in paging? answer a)It is a memory that is searched when a page is not found in page table b)It is part of the physical memory to hold process control blocks c)It is a bank of special registers inside the processor d)It is an associative memory that can do parallel frame search in hardware
- Consider the following page address stream: 2 1 4 3 5 3 2 4 5 2 1 2 4 3 1 Which of the following causes the most page faults to occur on a machine with 3 frames? Scheme that causes the most faults: a) First in First out b) LRU and FIFO are the same number of faults c) FIFO and Opitimal are the same number of faults d) All have the same number of faults e) Least Recently Used f) No faults occurs g) LRU and Optimal are the same number of faults h) Optimal NUMBER OF FAULTS CAUSED: a)What happens if a process tries to access a non-cacheable page? What steps are included in this procedure? Each phase should be separated into bullet points.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
- Define page fault, and what causes it. Which OS actions are required in case of page faults? What run-time cost (relative to memory access cost) is associated with a page fault? What is “thrashing”? (short answer is ok)In the MAC address table, a dynamic RAM is utilised to store MAC addresses. Assume the table size is 8000 and the memory access time is 100 nanoseconds. What is the worst-case look-up time if a binary search is employed to locate an address?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?
