First of all, what does a computer do? In our world today the word compute |kəmˈpyoōt| means to make a calculation, especially using a computer: modern circuitry can compute faster than any chess player. So is a photographic image made by a calculation of number values? Yes, to some extent with a digital camera. But graphics, an image on-screen was a side effect of computing, a part of the in and out communication with a computer. It was not what the computer did but how it communicated its answers after the question were typed into a computer with a keyboard. A monitor was just a convenient way to make a computer respond so its output could be read by human eyes.
