A computer can have a variety of input devices. This allows users to control the computer in different ways, or to put different kinds of data into the computer. The most common input devices is the keyboard. Another very common input device is the mouse. This is used to control the computer when the operating system has a graphical user interface.
The computer mouse is a hand-operated device that lets you control more easily the location of the pointer on your screen. You can make selections and choices with the mouse button. The mouse contains a rubber coated ball that rests on the surface of your working area or a mousemat. When the mouse is moved over the surface, the ball rolls. The ball’s movements up and down, left and right, turn the two axels inside the mouse. As they turn, detectors register the changing position. A small integrated circuit inside the mouse sends signals to the operating system, which instructs it to move the pointer on your screen.
The computer keyboard is an electronic device with keys arranged like earlier typewriter keyboards, but with extra keys. Because the output of the keys is controlled by the computer program, their function can vary. For example, the print screen key sometimes copies the screen to memory and sometimes copies it to a printer, depending on the program used. The arrangements of the keys varies but most desktop computers have an extended keyboard with keys divided into sections including the main keyboard, the function keys, the editing keys, and the numeric keys.
