Discuss the hardware support required to support demand paging. These checks have to be performed in hardware. A TLB could serve as a cache and improve the performance of the lookup operation. Consider a demand-paged computer system where the degree of multiprogramming is currently fixed at four.

The hardware support required to implement is simply the following: on each memory access, the page table needs to be consulted to checkwhether the page iswrite-protected. If it is indeedwrite-protected, a trap would occur and the operating system could resolve the issue.

https://en.wikipedia.org/wiki/Demand_paging
Basic concept. Demand paging follows that pages should only be brought into memory if the executing process demands them. This is often referred to as lazy evaluation as only those pages demanded by the process are swapped from secondary storage to main memory. Contrast this to pure swapping, where all memory for a process is swapped...
