Now this may seem a little strange, but I can’t say this enough: the computer does something because you have done something.

Well, how does the computer get the actions (or stimulus)? And how does it respond?

I’m glad you asked.

VARIOUS INPUT/OUTPUT DEVICES

Each computing device (be it a computer, printer, calculator, etc.) has what are called “input and output devices”. An input device sends information (or stimulus) to the computer, and the output device retrieves information (or response) from the computer.

There are several input and output devices. We use these to communicate with the computer so that we can get what we need to do. Input and output devices used to be exclusively input or output. However, in order to make your life a little easier, a lot of them receive and send data to the computer. This is what I mean:

You interact with the computer with this 5 easy ways via the following means:

11.    Keyboard

Resolution support, touch coordinates (if touch screen).Text and graphics

33.    Mouse

X, Y mouse movement changes. – (some initialization commands)

55.    Printer

Readiness, error conditions, etc. Document to be printed, Display messages.

With all these devices (there are many more), you may find it difficult to learn how to work and interact with a computer, unless they had some common interface (or method of communicating).
