Input or Output Operation


An input or Output Operation device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. A system is composed of I/O devices, control units, and software to carry out the I/O transaction(s) through a sequence of operations. The systems transfer information between the computer’s main memory and the outside world.

The river graceful from an input device like a keyboard to the main memory is called the Input Operation. On the other hand, watercourses that flow from the main recollection to an output device like a screen are called an Output Operation.

Input or Output Operation Examples

For example, a keyboard or computer mouse is an input device for a computer, though monitors and printers are production devices. Plans for the message between computers, such as modems and network cards, typically do input and output operations.

An Operating system Input or Output?

An Operating system Input or Output?

The operating system is mainly responsible for input-output functional interrupt, and error handling is a necessary term related to input/outputs. So, an operating system is reliable to handle interruptions and errors. It should also provide an interface between the device and the rest of the system.

The Role of Operating Systems in Computer

The critical role of the operating system in computer Input / Output is to manage and organize I/O operations and all I/O devices. The numerous devices connected to the computer need control, and it is a crucial concern of operating-system designers.

Difference Between an Input or Output Operation

Many input plans such as a keyboard, mouse, webcam, microphone, and more send information to a computer system for processing. Input devices only work for charitable data input to the scheme, and output plans accept the output after dispensing data from other devices. An output device, like Monitor, copier and more, shows the result of processing generated by input devices.

Various devices accept input from users or output data generated by a computer; therefore, they are input devices or output devices. One of the main differences between input and output plans is that input devices use to give input to the system by the users. In contrast, output devices are used to reproduce the output signals for the user. However, approximately devices are referred to as Input/output devices, as they can receive input and produce output.

For instance, as exposed in the above image, a keyboard is an input device sending an electrical signal to the computer system. A computer scheme accepts these signals as input, then explains them and produces or displays output to the user on the Monitor as text or images. The show tends data or output to the printer after processing in the lower half of the picture. Then, when the computer sends output to the printer it prints onto the piece of paper that considers output

Uses of Input or Output Operations

Input devices

An input device can obtain instructions from users on advancing info to another device. Still, it cannot accept data from a different system. After receiving input, it translates these data into electrical signals in binary code, which humans cannot understand, and only a digital computer can understand. There are many examples of input devices.

Control panel and Mouse: These are the input devices that the users use to give input to the computer. They direct the received input (Data) from users to the system. These input devices so cannot accept or display output (information) from the computer.

Another input device is a microphone that takes sound made by an input source and allows users to send audio into their computers. The received signal converts into a digital signal or amplifier as an analogue signal in the microphone.

Webcam: A webcam is a video camera that attaches to a computer and faces the user, which to capture pictures, makes a video by a computer system. Webcams are friendly to the Monitor of a desktop computer and builts into laptops. It takes descriptions as input from where it is pointy and for calling and taking selfies. However, most current webcams have a microphone, suggesting that users have a better sound quality while making videos.

Output Operations Devices

Output plans are the section of a computer expedient that receives data from another device and harvests output with the info. Although it cannot send data to another practice, it can forward data from a computer to another computer system. It purposes to take data from input devices and translate the digitized signals into a form that users can understand. There are various examples of output devices under

Monitor: A monitor is a part of computer ironware that receives data from a computer (output) and displays it on the system screen through its video card. Monitors can display information at a much higher resolution. Additionally, these are much like televisions and are also known as video screens, displays, video display terminals, or video display units.

Speakers: The most common output devices, speakers, receive sound data from a computer and play the sounds for users to hear. The main objective of the speakers is to produce sound or audio output for the listener. Although speakers use wit used with any, it is a device that cannot receive sound generated by users and refer that sound to another device.

Projector: A projector is an output expedient that accepts data from a computer (output) and projects that data or information as a picture onto a wall or screen or any large surface. It cannot receive data from a user and is also not capable of sending that data to another device. When you are showing video or images to a large group of people, a projector is more beneficial to use than a monitor because it displays data on a large surface that can be visible to many people.

Some Uses of Input/output  Operations Devices

An input/output device can accept data from users or another device and forward data to another device (output). Some examples of input/output devices are below. CD-RW drive and DVD-RW drive. These drives function for accepting data from a computer as an input to copy onto a writable CD or DVD. And this data contains on a CD or DVD sent by the drive to the computer.

USB flash drive: It refers to a keychain drive or data stick. USB flash drive. Thumb drive memory unit and pen drive. It is a portable storage device that saves or accepts data from a computer (input). It connects to a computer via a USB port and forwards data to a computer or another device.


An input/output device often known as an IO device is any computer. Hardware that allows a human operator or other systems to line with a computer. Devices, as the name proposes, are capable of delivering data (output) to and receiving data from a computer.

An input/output (I/O) device is a piece of hardware that can take, output, or process data. It receives data as input and provides it to a computer and sends it. Computer data to storage media as a storage output. The keyboard is the most recurrent and widely used input device for entering data into a computer.

Although there are some additional keys for performing other operations, the keyboard layout is similar to a typical typewriter. Generally, keyboards come in two sizes: 84 keys or 101/102 keys. But currently, keyboards with 104 keys or 108 keys are also available for Windows and the Internet.
