How does an output device give information?
next → ← prev Show There are many input devices such as a keyboard, mouse, webcam, microphone and more, which send information to a computer system for processing. An output device, like Monitor, printer and more, displays the result of processing generated by input devices. Input devices only work for giving input of data to the system, and output devices accept the output after processing of data from other devices. One of the main differences between input and output devices is that input devices are ones that are used to give input to the system by the users, whereas output devices are those, which are used to reproduce the output signals for the user. There are various devices that are used to accept input of data from user or output data generated by a computer; therefore, they are known as input devices or output devices. However, some devices are referred to as Input/output devices, as they can receive input and reproduce output. For instance, as shown in the above image, a keyboard is an input device, sending an electrical signal to the computer system. A computer system accepts these signals as input, then translates them and produces or displays output to the user on the monitor as text or images. In the lower half of the image, it is also shown that after processing, the computer sends data or output to the printer. Then, once the computer sends output to the printer, it is printed onto the piece of paper that is also considered output. Input devicesAn input device can receive instructions from users or forward information to another device, but it is not able to accept data from another system. After receiving input, it translates these data into the electrical signals in binary code, which cannot be understandable by humans, and only a digital computer can understand it. There are many examples of input devices, which are discussed below:
Output devicesOutput devices are the section of a computer device that receives data from another device and produces output with the information. Although it cannot send data to another device, it has the ability to forward data from a computer to another computer system. It functions to take data from input devices and translate the digitized signals into a form that can be understandable by users. There are various examples of output devices; some are discussed below:
Input/output devicesAn input/output device has the ability to accept data from users or another device (input), as well as forward data to another device (output). Some examples of input/output devices are discussed below:
Difference between Input and Output devices.The below table contains major key points of the difference between both Input and Output devices.

When a computer has finished processing input, it is sent back out of the computer ready to be used. Output can be sent to lots of different types of devices, including screens, printers, speakers and headphones. It can also be sent to lights or motors to make things light up or move.
How does an output devices work?An output device allows data to be transmitted by the computer in a human-friendly form, for example, sound being played through a speaker. Monitor - The main output device of a computer. It forms images by converting electrical energy into light in the form of tiny dots on the screen called pixels.
What is an output device that shows information?Monitors, commonly called as Visual Display Unit (VDU), are the main output device of a computer. It forms images from tiny dots, called pixels that are arranged in a rectangular form. The sharpness of the image depends upon the number of pixels. There are two kinds of viewing screen used for monitors.
How does an input device give information?Additionally, all input devices send data from the device over a cable or wireless transmission to the computer. For example, as you move a computer mouse, the data sent to the computer is the X-Y axis movements used to display the mouse cursor on the screen.
