I didn't understand the memory protection how to indicate the valid and invalid and also the herra

[@agbevichristiana1745]

And also the hierarchical of the page table schemes

[@SolvingSkills]

Can you be a little more specific on what your question is? In general, the protection bit is used as an extension of the page table to allow the OS to keep a check on the size of a page table

Very informative

Glad you liked it

Why page table is maintained in paging?

[@SolvingSkills]

because it is the only way the OS can locate the memory Frames allocated to a process. The OS uses the page table to translate a page number to its respective frame number. There is one separate page table for each process..

@@SolvingSkills thanks sir

[@SolvingSkills]

@@stviewsshorts no problem :)

Sir, Thank you for this informative video. Just one question though not relevant to this topic, when we talk about processes in terms of memory we use the term "Virtual Address Space" or "Address Space", where does this virtual address space is actually allocated? And the Address space and virtual address space are two different things? One more thing, can we find your video lectures on Process basics on this channel?

[@SolvingSkills]

Virtual or logical address space does not exist physically, it is when you imagine your process as a single entity on a paper maybe, when every process starts from address 0 and goes up to the address of its length. You can divide this address space into pages and those will be logical pages that can be allocated any frames in the physical memory..
