Explain swapping technique used in pre-3bsd unix systems?, Operating System

Assignment Help:

What are the disadvantages of swapping technique used in pre-3BSD UNIX systems?

  • If there is excessively much memory contention, processes are swapped out until sufficient memory is available.
  • As well, a few large processes are able to force many large processes out of memory.
  • A process bigger than non-kernel main memory cannot run at all.
  • User data segment and System data segment are kept back in contiguous main memory locations for swap-transfer efficiency, thus external fragmentation is a serious problem.
  • Throughput of the system is little compared with paged systems.
