From Processor To Display
What is the programming side of the keyboard's PrintScreen?
When I hit this button, what is the computer doing to give me the image that my monitor is displaying?
In the same arena, how does the computer tell the monitor what to display visually? I move the mouse and the cursor appears to be moving as a result of my manipulation, but I know it is some intricate process of programmed communication. What is happening here? not so much in lay men's terms but to the grit of it.
If I wanted to write code to alter what and how the monitor is told to display, and also how the mouse and keyboard receive their information and send it to the monitor... what languages and or avenues ought I look into? Is this all machine language? assembly? higher?
