The monitor is the screen you sit in front of. The most common type of monitor is called a Cathode Ray Tube (CRT). The cathode ray tube has three electron guns that fire electrons at the phosphorus covered screen. The phosphorus lights up in one of three colors (red, green, blue). These colors combine to create other colors. Computer monitors come in many different sizes. The most common sizes are 14", 15", 17", 19" and 21". We recommend that you get the largest monitor that you can afford.
In order to connect your monitor to the computer you will need a video card. The video card translates any output sent from the CPU into electrical signals that the monitor can use. Most modern computers have a Super Video Graphics Array (SVGA) adapter. Most new games and graphics programs require a 64 bit video card with at least 2Mb ram on it. The following is a picture of a video card.
