Address Units

      1     10,000

This permits First-Fit allocation of contiguous blocks of a resource. Initially the Map having one entry - address (block offset from the starting of the swap area) and the total number of resources.

Kernel treats every unit of Map as a group of disk blocks. On the allocation and freeing of the resources Kernel updates the Map for accurate information.
