Operating system may store information in these places:
? Real memory
? Virtual memory
? Expanded storage
The operating system may also move information from one storage location to another. This process is known as paging or swapping. Many operating systems page and swap to accommodate large amounts of information that do not fit into real memory. However, excessive paging or swapping can reduce the performance of many operating systems.
Monitor your operating system behavior with operating system utilities. Excessive paging or swapping indicates that new information is often being moved into memory. In this case, your system's total memory may not be large enough to hold everything for which you have allocated memory. Either increase the total memory on your system or decrease the amount of memory allocated.
