| Screen Font | Also called a rasterfont. The fontthat is displayed on your screen, which may approximate a printerfont so that documents look approximately the same on the screen as they dowhen printed. |
| Screen Saver | A moving picture or pattern that appears onyour screen when you have not moved the mouse or pressed a key on the computerfor a specified period of time. Screen savers prevent screen damage that iscaused when the same areas of light and dark are displayed for long periods oftime. Be careful when using a screen saver on a computer with an LCDscreen (most laptops and notebooks). A pixelon an LCD screen is on when its dark; therefore, blacking the screen as somescreen savers do would cause more damage. |
| script | A script is a series of OS commands. The term "batch file" means much the same thing, but is a bit dated. Typically the same sort of situations in which one would say DOS instead of OS, it would also be appropriate to say batch file instead of script. Scripts can be run like programs, but tend to perform simpler tasks. When a script is run, it is always interpreted. |
