Operating system controls and coordinates the use of hardware among application programs. It is also known as a Virtual address. It writes the unused page out to a reserved area of disk called the swap file. Another possible solution to the external fragmentation is to allow the logical address space of the processes to be noncontiguous, thus permit a process to be allocated physical memory wherever the latter is available. a1=2,an+1=an1+ana_{1}=2, a_{n+1}=\frac{a_{n}}{1+a_{n}}a1=2,an+1=1+anan. Windows The functionality of Mountain Lion is similar to Windows although it is generally regarded as easier to use. With that ensured, the larger question is what to do if the 500-kilobyte application space is filled.
