With virtual memory, the computer can use hard disk space as random access memory (RAM). The computer uses virtual memory to augment the ordinary RAM that is installed on the computer. If you reduce the size of the paging file, the Office program may not start correctly or may ...
Paging divides memory into sections or paging files. When a computer uses up its available RAM, pages not in use are transferred to the hard drive using a swap file. A swap file is a space set aside on the hard drive to be used as the virtual memory extension for the computer's RAM...
Memory, Pages/Sec: This counter is one of the most misunderstood measures. A high value for this counter does not necessarily imply that your performance bottleneck stems from a shortage of RAM. The operating system uses the paging system for purposes other than swapping pages because of memory...
