Which three parts of the computer receive input?

Computers are amazing machines that can do a lot of different things. But which three parts of the computer receive input from the user? And how does the computer receive input from the user? Understanding input and output in computers

In this post, we will be discussing these three questions in detail. So read on to learn more about input and output in computers!

Which three parts of the computer receive input?

The three parts of a computer that receive input are the keyboard, the mouse, and the touchpad. It’s important to understand the three parts that receive input. Input is data that enters through the input devices. A computer hard disk is used for long-term storage.

Understanding Input and Output in Computers: A Quick Guide

It’s important to be aware of the types of input and output devices.

Input Devices

Input devices are essential for using computers effectively. One of the first things that a computer needs to receive input from the user is an input device.

The different types of common input devices could be a keyboard, mouse, touchpad, trackpad, camera, microphone, modem, and joystick. The purpose of these devices is to allow the user to interact with the computer in some way. Understand how each of these works, and you’ll be able to use them to the fullest potential.

Examples of input devices

Below are some examples of input devices and their definitions.

Pointing device (Track ball, Pen & Paper, etc.)

A pointing device is a device that uses two needles to track the motion of an object on a screen. These devices are often used with computers in order to allow users to input text, arrows, and other complex movements. They are quite simple to use and can be comfortable for prolonged periods of time.

A trackball, pen & paper, or other input devices may have certain advantages over a keyboard-only system but they all require some level of familiarity and adjustment before they can be effectively used. Once you’ve got the hang of it, tracking down specific items and documents on-screen will become much faster and easier!

A pointing device should be used in combination with a keyboard for optimum results.

There are a variety of pointing devices available in the market today. They come with different features, prices, and uses. It is important to select the right device for your needs so that you can achieve optimal efficiency while working on your computer.


Scanning is an essential input device for computers. It helps you to capture documents, pictures, or other items and convert them into digital form. A scanner is also an essential input device for offices – it can be used for scanning paper documents as well as screenshots from computer screens.


Touchpads are a great way for users to interact with their computers in a more intuitive manner. Laptops tend to have larger touchpads while desktops have smaller ones. Used mainly for clicking on links or scrolling through pages, touchpads allow you to work smarter not harder.

There are two main types of touchpad- laptop and desktop models. Laptop models generally have the bigger pads as they’re used more often for general tasks such as browsing the internet and working on documents. Desktop models, on the other hand, are designed specifically for mouse use- making them the perfect choice if you’re looking primarily for computing power over convenience.


A keyboard is the most important input device on a computer. It’s where you type your commands and information into the system. It is the foundation of any computer. It’s where you type in what you want to do and it helps make your computer operate smoothly. A standard keyboard has a number keypad, function keys, arrow keys, and other assorted buttons.

To be effective, a keyboard needs to have good key spacing and feel. Furthermore, it should provide easy access to commonly used keys like Alt + Tab or Windows Key + Esc.


The mouse is a device used to move the cursor around the screen and click objects to select them for input or output. It allows users to point and click on the screen to drag and drop items, navigate through menus or programs, or highlight text. A good mouse also has a tracking feature that makes it easy to move around the screen without losing your cursor.


A microphone is a transducer that converts sound into an electrical current and vice versa. A microphone conveys information about the sounds to be recorded or reproduced from speakers around singers/or musicians and other people in public places like shopping malls, auditoriums, stadiums, etc.

How are inputs processed?

For processing, an input device sends data to a computer system. Computers need to constantly take input from various devices in order to carry out the task at hand. Keyboard strokes, mouse clicks, and other inputs are processed and used accordingly.

What do computers receive as input?

Input is an essential process in computers because they allow them to interact with external devices. Input refers to the data that is entered through a keyboard, light Pen, or mouse. We input audio from the microphone so audio and video are also used for input.

The input of a computer can come from text files, websites, images, and anything else that can be stored on the computer. I/O is a three-word acronym that stands for input, output, and output.

What are Output Devices and how do they work?

The output devices are the computer monitor, printer, projector, and speakers. output is data that exits through the same or different channels (e.g., print to paper). These parts of the computer give output to us.

Select an output device from the menu that pops up when you press Enter or F8. When using multiple outputs, be sure to set their order accordingly so that all devices are used in sequence. Understanding how output devices work is essential for using computing to its fullest potential.

Common types of output devices


Printers are the most common type of output device. You use them to print documents, photos, and other materials.


Computer monitors come in all shapes and sizes and can display everything from text files to pictures. Monitors use backlighting and often have features like tilt adjustment for easier viewing from different angles.

You’ll need an interface to connect your monitor to your computer. This is usually provided by a graphics card, but sometimes it’s built into the motherboard.

How do they work?

When you’re using a computer, output devices (monitors, printers, etc.) work together with input devices (keyboard, mouse, or touchpad) to produce the images and text that are on your screen.

Which computer parts give output?

The parts of a computer that give output are the computer monitor, printer, screen projector, and speakers. The output of a computer is displayed on the screen and often includes graphical elements like graphs and charts.

There are a variety of different types of outputs, and each has its own purpose. For example, a printer might output text, while a monitor screen might output graphics.

FAQs: Which three parts of the computer receive input?

Let’s cover some frequently asked questions that people asked about related to this post. This post gives appropriate answers to all these questions.

What is input/output and what does it involve in computers?

Input/output is the process of exchanging information between a computer and its environment. It involves the reading of data from a device such as a keyboard or a disk, and the writing of data to a device such as a printer.

Can I prevent my computer from becoming overloaded due to too much input?

There is no one-size-fits-all answer to this question, as the amount of input a computer can handle will vary depending on the hardware and software configuration of the computer. However, some general tips for managing input on a computer include disabling unnecessary programs, using a task manager to monitor processor and memory usage, and configuring Windows settings to reduce background processing.

How do I control the amount of output my computer sends to the external world?

To control the amount of output your computer sends to the external world, you can use a software application such as “System Preferences” in macOS or “Monitor” in Windows.


Input and output in a computer system are essential for the proper functioning of the computer. In this blog, we have covered the different aspects of input and output in detail. By reading through this guide, you will be better equipped to understand how your computer works and how to give input data correctly.
