How does paging work in computers?
An example of an AI chatbot conversation about how paging manages memory in computer systems.
Can you explain how paging works in computers?
Sure! Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory. It divides the process's memory into fixed-size pages.
What happens when a program accesses a page that is not in memory?
When a program accesses a page that is not in memory, a page fault occurs. The operating system then retrieves the page from disk and loads it into memory.
How does the operating system decide which page to replace?
The operating system uses page replacement algorithms, like Least Recently Used (LRU) or First-In-First-Out (FIFO), to decide which page to replace.
Are there any advantages to using paging?
Yes, paging allows for more efficient use of memory, simplifies memory allocation, and helps prevent fragmentation.
