Hi
When I press the key "A" on the keyboard, it is interpreted as "1000001" where "1" stands for high voltage and "0" for low voltage. In other words, pressing the "A" key generates a square wave having two high levels and five low levels. But how does computer display/draw "A" on the screen after getting this signal? Does it have some built-in function which tells it how to spread pixels on the screen so that the spreading suggests the shape "A"? Thanks for your help.
Regards
