A person can spit into a cup and the computer can see what kind of illness they have. The computer database will be filled with every single type of virus, and when the cup is put into the machine, within an hour or so, the computer will have found what is wrong with you.
Computer coding can include art and entertainment. When you have a bunch of lights that need to go on and off at certain times, humans can’t time exactly when to flip the switch or push the button, so people code a computer to turn the lights on and off at the right time. Another example of computer coding in art and entertainment are animated movies. They code the computer to do the motion, but the humans draw the actual pictures to create the whole movie.
