9.2 Discuss the hardware support required to support demand paging. Answer: For every memory access operation, the page table needs to be consulted to check whether the corresponding page is resident or not and whether the program has read or write privileges for accessing the page. These checks would have to be performed in hardware.

9.2 Discuss the hardware support required to support demand paging. 9.3 What is the copy-on-write feature and under what circumstances is it beneficial, to use this feature? What is the hardware support required to implement this feature? 9.4 A certain computer provides its users with a virtual-memory space of 2 1" bytes.The computer has 2 18 bytes of physical memory.

9.5 Discuss the hardware support required ... At a minimum, demand paging requires hardware to support the logical to physical address translation. Required hardware includes a translation look-aside bu er to hold page table entries. In addition, each page must have an associated valid bit (to determine if the page is in memory).

Discuss the hardware support required to support demand paging. An operating system supports a paged virtual memory. The central processor has a cycle time of 1 microsecond. It costs an additional 1 microsecond to access a page other than the current one. Pages have 1,000 words, and the paging device is a drum that rotates at 3,000 revolutions
https://www.cs.uic.edu/~jbell/CourseNotes/OperatingSystems/9_VirtualMemory.html
This is known as pure demand paging. In theory each instruction could generate multiple page faults. In practice this is very rare, due to locality of reference, covered in section 9.6.1. The hardware necessary to support virtual memory is the same as for paging and swapping: A page table and secondary memory.

Virtual memory is commonly implemented by demand paging. pure demand paging never brings in a page until that page is referenced. The first reference causes a page fault to the operating system. The operating-system kernel consults an internal table to determine …

9: Virtual Memory 4 VIRTUAL MEMORY Demand paging When a page is touched, bring it from secondary to main memory. Overlays Laying of code data on the same logical addresses - this is the reuse of logical memory. Useful when the program is in phases or when logical address space is small.

Demand Paging Hardware Support. Hardware support to demand paging. Page Table: Table has the ability to mark an entry invalid through a valid-invalid bit/special value of protection bits. Secondary Memory: Holds pages that are not in main memory (disk), known as swap device and section of disk used for this purpose is swap space/backing store.

https://en.wikipedia.org/wiki/Demand_paging
In computer operating systems, demand paging (as opposed to anticipatory paging) is a method of virtual memory management. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it and that page is not already in memory (i.e., if a page fault occurs).
