QUICK FIT ALGORITHAMS
Here we keep apart lists for holes and processes. Therefore this reduces the searching time for holes
Hole list and Process list. If we organize the list of holes in an ascending order we are able to easily find out the holes according to the size. And we are able to easily insert the processes into the holes.
But here it will be extremely difficult to merge some holes which are created in between two processes. For the reason that we are using separate lists for process and holes.
