Preparing for finals and working out some exams from previous years. Please answer the following disk scheduling:

Problem #1 (17 pts) Consider a system with 16 running processes. All their page tables and data must be held in memory for system performance Each process has access to a virtual memory of size 2 Bytes .The size of a page is 2 Bytes 30 The total amount of physical DDR RAM available in the system is 2 Bytes 1) 2) 3) How large (number of bits) is a virtual address generated by the processor? (3 pts) How large (number of bits) is a physical address needed to access the RAM? (3 pts) Show on a graphic the partitioning of the virtual (page#, offset) and physical (frame#. offset) address (2 pts) 4) 5) Compute the number of frames in the system? (3 pts) Each entry in the page table contains valid/invalid bit, three protection bits, a dirty bit and 2 bit for second chance implantation What is the total overhead (size of a page in Bytes) required by the OS to manage a process memory (5 pts) a. What is the total memory overhead of the system, when all threads are running? (2 pts) b
