On systems with 4 GB virtual memory space, if the page size is 1 MB, answer the following questions:
(1) How many entries can be stored in the page table? explain
(2) Describe the predictable overhead (or advantage) of I/O time and internal fragmentation when the page size changes to 4 KB. (explain)
(3) When the page size is changed to 4 KB as shown in (2), how many frames and the possible internal fragmentation size are needed to load 80,000 bytes of the process into the main memory?
(4) In a system with a hit ratio of 90%, the time taken to search the TLB is 200 nanoseconds and the time taken to access the main memory is 1 microseconds. What is the effective memory access time of this system?
