Adobe Photoshop isn't useful only to professional photographers and graphic designers. Small businesses use the software to craft brochures, advertisem*nts, logos and Web graphics. Photoshop uses three different memory caches that allow users to revert to a previous version of the project, known as Undo and History, and to copy an image from one location to another, known as Clipboard. As you work on an image and the memory caches grow, you may experience slow computer performance. Deleting the caches increases Photoshop's performance.
