the computer can do many different things in many different ways.  first data is entered into the computer through input devices. then it is stored in the CPU. next it is printed or saved on an output device.

As I was walking to the computer I noticed my input device was wet. I was having a bad enough day. This morning the mother board on my computer just broke down. The out put device was fine which meant it wasn't a total loss. Well the CPU is gone a very bad day had happened.
