Pixel

A pixel is an individual dot that makes up a graphic image. For example, a 640 x 480 monitor is 640 pixels wide and 480 pixels high. If you are doing banner advertising, you will often see the specification that your banner must be 468 x 60; this means your banner can be 468 pixels wide and 60 pixels high. Your graphics editor program will allow you to determine your banner's size.
