There's an old saying that's something like this: Give a man a fish, and he'll eat for a day. Teach a man how to fish, and he'll never go hungry.
Are you asking us to give you a fish or to teach you how to fish? We'll (or at least I'll) be happy to teach you, but we (or at least I) WILL NOT give you a fish.
In any case, I sure hope your teacher didn't give you that question worded exactly like that. Otherwise, that's sloppy and difficult for anyone to answer, especially if the teacher made the mistake of calling the computer tower/chassis the "CPU," as the "CPU" is really the processor, or Central Processing unit
this it what the question says
you have taken holiday photos with your digital camera and downloaded the photos to your computer.your friend wants copies of two photos printed on your colour printer. explain the interaction that will take place between the camera(input device) the CPU and the printer (output device)
sorry about that i miss worded it
and id like to be taught how to fish that way you actually get sumwere in life
