Difference Between Input and Output Devices- Input vs Output Devices

By Aina Parasher|Updated : April 21st, 2022

Difference Between Input and Output Devices: By transporting data into and out of the computer system, input and output devices allow the computer system to communicate with the outside world. Data is entered into the system using an input device. Data is sent out of the system via an output device.

I/O devices are commonly used to refer to input/output devices. They are immediately connected to a device controller, which is an electronic module located inside the systems unit. I/O devices, such as hard discs, are also referred to as secondary memory devices. We will check the differences between input and output devices in the sections provided below.

What is an Input Device?

Input devices are the parts of a computer system that take data and instructions from the user and turn them into a pattern of electrical signals in binary code that a digital computer can interpret. Examples of input devices include a keyboard, a mouse, and so on.

These are used to directly input commands as well as information and data. The user can utilize these devices to enter commands/instructions and data into the computer. While an input device is capable of sending data, it is not capable of receiving data from another device. These are user-controlled and have complex coding.

What is an Output Device?

Output devices are the parts of a computer system that transform digital signals into user-friendly formats. In general, output devices are referred to as the inverse of input devices. Data is also sent from one computer system to another using output devices. Examples of output devices include a printer, a monitor, speakers, and so on.

The data processing findings are reproduced, interpreted, or shown on the output devices. An output device can take data from another device and use it to produce output. Because the computer controls the output devices, the user simply needs to view the outcomes and is not required to learn the complete process.

What is the Difference Between Input and Output Devices?

Input devices solely function to provide data to the system, whereas output devices take data that has been processed by other devices. We have discussed in detail the input and output devices. Further, we will discuss the differences between input and output devices. The following table summarises the significant differences between the two.

It accepts the user's data and transmits it to the processor for processing. It receives the data from the processor and returns it to the user.
It can send data to another device, but not the other way around. It can collect data from another device and use it to generate output. However, you won't be able to transfer data to another device.
For example, a keyboard, an image scanner, a microphone, a pointer, a graphics tablet, and a joystick.For example, monitors, printers, plotters, projectors, and speakers.

FAQs on Difference Between Input and Output Devices

  • The major difference between input and output devices is that an input device transmits data to a computer system, which is then processed, and an output device reproduces or displays the outcomes.

  • An input device is a piece of equipment that sends data and control signals to a computer or other information appliance. Keyboards, mice, scanners, cameras, joysticks, and microphones are examples of input devices.

  • Any piece of computer hardware that translates information into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment is referred to as an output device. Text, images, haptic, audio, or video are all examples of output devices.

  • The difference between input and output devices based on their functioning is that input devices help to enter the data processed by the computer whereas, an output device generates results from the processed data to provide the desired result to the user.

  • The difference between input and output devices in terms of their use is mentioned below.

    • The input device assists the computer in receiving user instructions.
    • The output device assists the computer in producing or displaying data to users.
