Why are the page size the number of pages 4 in the virtual address space and the number of page frames in the physical address space all a power of 2 Explain?

Page sizes, the number of pages in virtual address space, and the number of page frames in physical address space are typically powers of 2 because this alignment simplifies memory management and addressing. Using powers of 2 allows for efficient bit manipulation, which facilitates faster calculations for memory addressing, such as shifting bits for page offsets. Additionally, it aligns well with binary systems used in computers, making it easier to design hardware and software that can handle memory efficiently. This uniformity also aids in ensuring optimal use of memory resources and reduces fragmentation.
