Demand paging

Tag: demand-paging

Aliases: demand paging

A virtual-memory mechanism that uses disk as an automatically-managed extension of DRAM: a page is brought into a physical frame only when it is referenced and is evicted back to swap when DRAM is full. Hit handling is in hardware, miss handling (page fault) is in software.
