Demand paging requires additional hardware support, compared to paging.

Hierarchical paging can be used as a replacement for demand paging.

Both demand paging and paging support shared memory pages.

Paging improves overall memory access time

TLB improves performance with demand paging, but not necessarily with Paging.

TLB hit ratio has zero impact in effective memory access time in demand paging.

Calculations of number of bits for page number and offset are same in paging and demand paging.

With demand paging, it's possible to have user programs bigger than physical memory.

The meaning of valid-invalid bit in page table is different in paging and demand-paging.

With paging, it's possible to have user programs bigger than physical memory.

Paging requires some hardware support in CPU

Demand paging always increases effective memory access time.
