Question

Q1 Consider a virtual memory system that can address a total of 232 bytes. You have unlimited hard disk space, but are limited to only 8 MB of semiconductor (physical) memory. Assume that each 4 KB in size. (a) How many bits is the physical address? (b) What is the maximum number of virtual pages in the system? (c) How many physical pages are in the system? (d) How many bits are the virtual and physical page numbers?

Answer 1

Answer:

A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in the page table. It is the smallest unit of data for memory management in a virtual memory operating system. Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory pages are mapped by the operating system.[1][2][3]

A transfer of pages between main memory and an auxiliary store, such as a hard disk drive, is referred to as paging or swapping.[4]
