Input and Output Devices Question and Answers | Basic Computer Knowledge
Updated: by Computer HopeAn sends information to a computer system for, and an reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device. Most devices are only input devices or output devices, as they can only accept data input from a user or output data generated by a computer. For example, as you can see in the top half of the image to the right, a keyboard sends electrical signals, which are received by the computer as input. Those signals are then interpreted by the computer and displayed, or output, on the monitor as text or images. In the lower half of the image, the computer sends, or outputs, data to a printer, which will print the data onto a piece of paper, also considered output.
A pointing device is an input interface specifically a human interface device that allows a user to input spatial i. CAD systems and graphical user interfaces GUI allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the pointer or cursor and other visual changes. Common gestures are point and click and drag and drop. While the most common pointing device by far is the mouse, many more devices have been developed. However, the term "mouse" is commonly used as a metaphor for devices that move the cursor. For most pointing devices, Fitts's law can be used to predict the speed with which users can point at a higher speed.
