How does paging work in memory management?

Can you explain how paging works in memory management?

Sure! Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory. It divides the process's virtual memory into blocks of physical memory called pages.

What are the benefits of using paging?

Paging allows for more efficient use of memory, as it helps to avoid fragmentation. It also enables processes to use more memory than is physically available by swapping pages in and out.

How does the operating system handle page faults?

When a page fault occurs, the operating system pauses the process, locates the required page on disk, and loads it into memory. It then updates the page table and resumes the process.

Are there any downsides to paging?

Yes, one downside is the overhead of managing page tables and handling page faults, which can slow down performance if they occur frequently.
