Memory cache is RAM-based memory. It enables the browser to store Web pages in RAM for faster loading. In Netscape Navigator, memory cache is set in the Network Preferences Property Sheet, in the cache dialog box. Memory cache is represented in number of kilobytes (rather than megabytes). If a user's computer has 12 meg of RAM, that corresponds to 12,000 kilobytes. If the computer is running slowly, the user can choose the Clear Memory Cache Now button to free up RAM. In Internet Explorer, memory cache cannot be readjusted. Disk cache may be readjusted on the Advanced tabsheet of the Options properties sheet on the View menu. Set the memory cache value conservatively. It should be no higher than half the amount of available RAM, so that other applications can run while the browser is in use. If a user's computer has 12 meg of RAM, the value in the Memory Cache box should be no higher than 6000 Kilobytes.
