Here’s how demand paging works step-by-step: 1.) Process Request: A process requests access to a specific page in memory. 2.) Page Table Check: The operating system checks the page table to see if the requested page is in physical memory. 3.) Page Fault Detection: If the page is not in memory, a page fault occurs. If the page is already in memory, the process continues execution. Locate Page on Disk: The operating system locates the missing page in secondary storage (e.g., hard disk or SSD). 4.) Allocate Frame: A free frame in physical memory is allocated to load the page. If no free frame is available, a page replacement policy (e.g., LRU, FIFO) is used to evict a page. 5,) Load Page into Memory: The requested page is loaded from disk into the allocated frame in memory. 6.) Update Page Table: The page table is updated to reflect the new location of the page in memory and mark it as present. 7.) Restart Process: The process is restarted from the instruction that caused the page fault. Repeat: Steps 1-7 are repeated whenever a page fault occurs for other pages.

I am getting a bit confused between threads and paging. would be great if someone attaches some relevant link in reply.

[@shanthgaitonde]

They are two very different concepts. Paging is part of memory management while threads are related to processes. A page is a block of memory while a thread is a sequence of instructions to be executed.

[@twi4458]

Thread is working in action(a light weight process, which helps process to complete faster), Paging is a concept of memory management in which program is loaded in RAM from where thread in accessing the code Quote me If I'm wrong.
