VARIABLE PARTITIONING

We can differ the partitions and change the location according to the size of the process.

 

50k

40k

30k

20k

10k

 

 

 

 

 

 

 

 

 

 

10k

Here if a 10k process enters we are able to make a space of 10k for that process. According to the process enters we are able to divide the memory into several partitions If one process is over the space for that will be free. This free space is called as hole. If another process come of smaller than the size of the free space that will move to the free space.
