How many jobs can be run concurrently on MVT?


  • 15 jobs can run concurrently on Multiprogramming with a Variable number of Tasks (MVT) .
  • Job can move from one partition to another because of dynamic address binding
  • MVT is the memory management technique in which each job gets amount of memory it needs- even at cost of swapping other processes.
  • The partitioning of memory is dynamic and changes as jobs enter and leave the system.
  • MVT makes more “efficient” use of resources.
  • MVT however suffers from the problem of internal fragmentation
