The simplest card can display only ASCII text on the monitor. A Hercules card can display text and two color (black plus one color) graphics. This is called monochrome. A CGA card can display text in up to 16 colors or graphics in up to 4 colors. An EGA card can display text and graphics in a higher resolution, meaning more, smaller dots, in up to 16 colors. And a ~ text/331/2 VGA card is even higher resolution and can handle up to 256 colors. ~ text/329/21 The monitor does not know about text. All it knows is how to put dots on the screen.

For instance, an A is composed of these dots: ~ rectangle/458/113/469/123 rectangle/445/124/456/135 rectangle/471/124/482/135 rectangle/433/137/445/148 rectangle/483/136/494/147 rectangle/421/150/433/162 rectangle/496/149/507/161 rectangle/410/163/421/175 rectangle/508/163/520/176 rectangle/399/176/411/187 rectangle/520/176/532/187 rectangle/435/150/447/162 rectangle/483/149/494/161 rectangle/450/150/460/162 rectangle/472/149/481/161 KB/435/150/464/166 KY rectangle/435/150/445/162 rectangle/447/150/456/162 rectangle/459/149/469/161 changepattern1 flood/462/117 flood/451/127 flood/477/129 flood/439/142 flood/488/142 flood/426/155 flood/437/153 flood/451/158 flood/462/154 flood/476/153 flood/487/157 flood/500/156 flood/414/167 flood/402/182 flood/513/168 flood/525/182 KB/389/140/399/145 fatbit 445/148/0 444/148/0 443/148/0 442/148/0 441/148/0 440/148/0 439/148/0 438/148/0 437/148/0 436/148/0 435/148/0 434/148/0 433/148/0 KV/421/150/456/162/422/149 fatbit 471/161/1 471/160/1 471/159/1 472/159/0 472/158/0 471/158/1 472/158/1 472/159/1 471/157/1 471/156/1 471/155/1 471/154/1 471/153/1 471/152/1 471/151/1 471/150/1 471/149/1 KV/399/112/533/188/407/94
