Hey! You're doing great on your first day! Do you have any questions?
I've finally found someone who gets it! How would you like to be assistant manager?
Yeah, actually. How does the computer on this machine function? I mean, like, all I have to do is press buttons.
There is something called inputs and outputs when you are talking about computers. The inputs are the things you do to make the computer perform a task. For example, pressing buttons or tapping a screen. The outputs are things that the computer does back to you, like playing music from a speaker. Without them, it would be almost impossible to communicate with the computer.
Oh Wow! I thought you were just going to tell me that the buttons make the computer do something, not that long impressive speech!
