Difference Between Input Devices And Output Devices

An input device is a piece of hardware that sends data into a computer, while an output device is a piece of hardware that receives data from a computer.

The data that is sent by the input device to the computer for processing is reproduced or displayed by the output device. While most devices are only input or output devices, some can also accept input and display output.

A system is only as good as its input and output devices. Input devices are devices that allow us to enter data into a computer system.

Output devices are devices that allow us to see or hear the results of the data that has been processed by the system. The most common input device is a keyboard, while the most common output device is a monitor.

Input Devices

Input devices are devices that receive information from the user. All input devices are connected to the computer so that they can communicate with each other and exchange information. The type of connector used depends on the signaling mode and protocols required for the communication. Examples of input devices include keyboards, mice, touch screens, and joysticks. 

Output Devices

Output devices are devices that generate information for the user. These devices may be internal or external. Internal devices are those that are built directly into the device.

Output devices are those that take data from a computer and turn it into a human-readable format. Output devices can be something as simple as a single light or an alphanumeric character, or something more complex like a text display or a pointer that can display pictures or text.
