A computer is a machine that inputs (takes in) facts and information (known as data), and then processes (does something to or with) it. Afterwards it outputs, or displays, the results for you to see. Data is all kinds of information, including, pictures, letters, numbers, and sounds. There are two main parts of computers, hardware and software. Hardware is all of the parts of the computer you can see and touch.
