title: Is frame number actually base address of memory where pages stored in paging?
body: <p>My question is related to the paging system of memory management.
  I'm a little bit confused about the frame number.
  Is frame number actually base address of memory where a page stored?
  If it is base address then why OS does multiplication frame number × page size (page no. × frame size + offset) to find the physical address.
  Can't it just add offset with frame number to find a physical address?</p>
