A process is divided into multiple pages and placed in frames of the main memory. but if the number of pages is greater than the number of frames then all the pages cannot be fit into the frames available. Hence some pages of the process wouldn't be in a frame but would be in hard disk. Hence when cpu requests for such a page,the page table entry holding the frame number for that page would be empty since it's not yet loaded to a frame in the main memory and is still in the hard disk.It would also have its valid bit set to 0 => invalid page because its in hard disk and not main memory.This causes page fault. This page fault generates a trap and hence the mode bit changes from user to kernel or OS mode.Then the OS fetches this page from the hard disk and places it in a frame using Replacement algorithm if no free frame available in the main memory.Then it updates the page table entry and valid bit.It sets the frame number where the page was placed and the valid bit is set to 1.

Sir the way you explain and making it free for students giving us so much of information really thank u so much no words. Not just this i am watching, dbms,os which are very helpful.
This is the best topic i have ever encountered in Computer Architecture.. And Thankyou Sir for making this video... Kaas aesa koi video mujhe bahot pahele mil chuka hota..
loved it , very clarifying. The way you use mix of hindi and english to explain the examples is very nice. Specially helps Indian students understand core concept properly and its a great crash course on the topic for a guy like me who is trying to revise some topics. thanks a lot. Please continue the great work, wish you a lot of success ahead. +1 subscriber. :)
i have seen almost all your videos ,that were very -very heplful for me to learn the concepts in depth of operating system specially like (virtual memory,paging,segmentations).sir , i have also seen that your concepts is so good .you explain the concepts in so depth,that help me in solving good questions. thank you ,sir keep it up sir. god bless you. om sai ram.

Your explanation is just awesome.. I have watched all video of.. CPU scheduling. Disk mgmt algorithm, vm. Your way of explaining things by giving example is nice. Thank you. Please make videos on probability in mathematics too.
You explain the things very well, thanks a lot. A small suggestion whilst explaining you tend to repeat the same thing multiple times, on youtube one can easily rewind so you should stop doing it and also cause of it the video size increases.
Very good explanation sir bht easy way Mai samjh aagya hai plzz make more video on page replacement sir apke elawa kisi or ka video samjh nh ata sai se
