Paging

Operating systems are responsible for managing memory for the user. Managing memory can be done by paging or by segmentation.

Paging

  • Paging splits the main memory (RAM) into 4 kb sections known as pages.
  • When programs run they are allocated a set number of pages to run in.
  • Programs can be split across lots of pages that are non-contiguous (not all together).
  • This is managed by a table map.

Performance

  • Performance is not affected by having non-contiguous pages for your program.
  • Any pages being used that are not active can be sent to virtual memory to free pages up for other tasks.
  • Performance may be affected if some programs are split (e.g. when parts of a looping function are split across pages)
