Difference Between Input Devices and Output Devices

An input device is essentially a piece of hardware component used to provide data and control signals to an information processing system such as computer or information device. Common inputs devices on modern computers include keyboards, mouse and touch screen which are used to enter commands and data directly. Other examples of input devices include scanners, digital cameras, joysticks and microphones. An output device is any hardware component that use received data from a computer to perform a task. The data received by the output device can be text, graphic, tactile, audio or video.

What is Input Device?

An input device is essentially a piece of hardware component used to provide data and control signals to an information processing system such as computer or information device. Common inputs devices on modern computers include keyboards, mouse and touch screen which are used to enter commands and data directly.

Other examples of input devices include scanners, digital cameras, joysticks and microphones. An output device is any hardware component that use received data from a computer to perform a task. The data received by the output device can be text, graphic, tactile, audio or video.

Three most commonly used output devices are a printer, a monitor and speakers. A printer is used to generate a hard copy or graphics on a physical medium such as paper. Speakers are used for communicating with the user by voice or for playing music or the soundtrack to a movie whereas a monitor displays visual output such as text, graphics and videos on a screen.

Output and input devices are two types of hardware devices. The main difference between them is that input devices are used to send data into the computer while output devices are used to take data out of the computer.

Most devices are either input devices or output devices, as they can only accept data input from a user or output data generated by a computer. For example a touch screen displays visual output and takes input from a user. Other devices like printers also function as document scanners. Viva Differences. An input device is any hardware device which enables the user to enter data and instructions into a computer.

An input device can send data to another device but it cannot receive data from another device. An output device can receive data from another device and generate output with that data, but it cannot send data to another device. Input devices are necessary for a computer to receive commands from its users and data to process. Output devices are necessary for a computer to share its results and prompt users for more information and commands. Input devices are relatively complicated as they have complex coding that ensures that the user can interact with the computer correctly.

Output devices are simpler for the user since they only see the results and do not have to learn the processes. Printer, monitor, speakers, projector LCD projection panels, computer output microfilm, plotters etc.

It cannot accept sound generated by users and send that sound to another device. Devices used to get input signal Devices use to get output signal.

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. For instance, as shown in the above image, a keyboard is an input device, sending an electrical signal to the computer system.

An input device sends information to a computer system for processing , and an output device 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 shown in the top half of the image, a keyboard sends electrical signals, which are received 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. Then, that data is printed onto a piece of paper, which is also considered output.

Difference Between Input Devices and Output Devices

Generally, the input and output devices are considered a communication tool, through which a certain system for information processing like the computer delivers another information to the users. The data or signals the computer receives from a source, are known as an input, while the response data and information which are processed as a reaction to these inputs, and which are further transmitted to a certain destination are known as an output. On a computer with a general purpose commonly used input devices are, for example, the mouse and keyboard, and examples of output devices are the monitor, printer, speakers and so on. Input devices serve the computer user to enter data into the computer.

The main difference between input and output devices is that the input devices are used to send data into the computer while the output devices are used to take data out of the computer.
