The book says, page fault handling, the system will check the failure types of pages, if the zero page, will just apply to reset page frames, will fill in the page table entries page frames,
- the question, "will just apply to reset page frames, the page frames, fill in the page table entries" this action is hardware circuit is made, a reset a page frames?
If is to rely on software to do, a word a word by CPU to reset, too slow?

Consult!
