Say you're designing your own operating system, and you want to implement your own paging system. Give one advantage of having small page sizes and give one advantage of having large page sizes.

Answer and Explanation:

Advantages of having large page sizes: Smaller page table, less page faults, less overhead in reading/writing of pages.

Advantages of having small page sizes: reduces internal fragmentation, better with locality of reference.

Answer and Explanation:

Paging in operating system design help to manage memory algorithms. Although paging reduces external fragmentation, it also brings about internal fragmentation. The smaller the page size even though might result in smaller page tables reduces the amount of memory that is consumed due to internal fragmentation. The advantage of the large page size is that there are fewer page table entries (smaller page tables), and smaller TLB. It also reduces overall memory management processing on the system.
