Explain the Reference Count

The system relates a reference count along with each memory area to point out the number of its active users. This number is incremented while a user accesses that area and decrements while user stops using that. The area is free if the reference counts drops to zero. This scheme is extremely simple to implement though incurs incremental overheads.
