Installing More Memory

Page 14 highlights

Some operating systems, such as Windows for Workgroups, allocate a fixed disk cache, which you can configure directly. Others, such as Windows NT and Windows 95, use a dynamic allocation mechanism that configures the disk cache according to the amount of memory available. The memory used by the disk cache will not be available for use by your applications. When determining your memory requirement, remember to add an extra allowance for the disk cache. Installing More Memory If your PC has less memory installed than your operating system and applications require, then installing more memory will significantly improve your PC's performance.
