Input And Output Devices Examples
input and output devices examples list
Input devices and output devices play an essential role in a computer’s operation. We can instruct the computer to perform a particular action; then, we can receive a response on an output device. Various input and output devices are available on the computer. This part of the computer transports data from one part of it to another.
In this article, we will discuss the input and output devices examples that may be connected to a computer and their uses.
What are the input devices?
Input devices send data from one computer to another. Many input devices are capable of interacting with or controlling the computer. There are many different input devices and input and output devices examples are many, including the mouse and keyboard.
Input devices deliver data to computers, whereas output devices receive data from them.
Types of the input device:
1. Direct input device.
Generally, the term direct input device is used for hard disks, optical disks, and floppy discs.
2. Indirect input device.
Direct Input Devices are keyboards and scanners. Signs and letters are input into the computer by these devices. Unlike a human, a computer can’t understand letters and signs. Computer language must be translated into these signs and letters before they are entered into the system.
Functions of the input device:
Computer input devices allow data to be entered into the computer. Users communicate with computers through input devices; they use various types of data. These devices can be used to store music, images, and even videos. Computer peripherals such as output devices and storage devices are frequently considered input devices.
Importance of input device:
Having an input device is crucial to modern life because it allows you to communicate with a computer and add data. A computer without input devices may run automatically, but its settings are not changed, errors are not fixed, and other user interactions cannot be modified. You cannot add new information without an input device (e.g, text, commands, documents, pictures).
computer input devices examples
Input devices are devices that transmit data to and are controlled by a computer. It allows the computer to process raw data. Let me share with you the computer input device examples. And we have added input devices examples with pictures so that you can understand it better.
An input device that is common and widely used in computers is the keyboard. Additional keys are allowing the user to perform other functions than those found on a traditional typewriter. The standard keyboard size is 84 keys or 101/102 keys. However, now 104 key and 108 key keyboards are available for Windows and the Internet.
A keyboard with 104 keys, alphabetic letters, numbers, arrows, and a set of function keys is the most common on the market. But the criteria for setting the number of keys are not well defined.
Most people use a mouse for pointing. Traditionally, a mouse used a rollerball embedded underneath the device to detect movements, but modern mice use optical technology (lasers) to detect movements and control cursor movement. There are two buttons on the mouse – right and left, plus a scroll wheel in the center. It is normally used on a flat surface. A mouse can also be connected either directly or wirelessly like a keyboard. Touchpads are available on laptop computers that can replace mice, and a user’s finger can be used as a mouse on smartphones and tablets.
Another computer input devices examples are the joystick. It looks like movable vertical handles with a vertical stick-shaped design. The cursor on the screen can be moved in any direction by using these computer input devices.
An upper and lower ball spherical end is attached to the stick. It is connected by a socket to the lower spherical ball. There are four directions in which you can move the joystick.
Another common input device is digital cameras. Photographers use digital cameras to record images and videos, which are stored on memory cards in digital form. Additionally, it can record sound and parameters associated with the shooting as well as capture and digitize images.
We can create documents with digital cameras in standard formats for our computers and other devices immediately after taking a photograph. CCD sensors or Charge Coupled Devices are used as the focal planes in digital cameras. It is used both by amateur and professional photographers to capture cherished moments.
Pen-like devices like light pens can also be used as pointing devices. Light-sensitive devices were used to write or draw on the screen. Pen-like devices like light pens can also be used as pointing devices. Light-sensitive devices were used to write or draw on the screen.
Photocells and optical tubes are used for the system. When the tip of the pen moves on the screen, the photocell sensor element on the pen detects the position of the screen and signals the CPU.
An input device known as a trackball is commonly used instead of a mouse on laptops and notebook computers. Using the finger on the ball, you can move the pointer inside the half-inserted ball. Trackballs require less space than mice because the body of the device does not move.
A computer microphone can receive recorded or live sound. For example, microphones are used in voice recorders, online chats, and singing.
In a microphone, sound vibrations are converted into an electrical signal that is listened to via speakers. Mics have the significant advantages of being cheap and simple, as well as having good response sensitivity.
The two main differences between webcams and digital cameras are as follows. The first is that they can’t function independently of a computer, and the second is that they do not have built-in memory. Most webcams are used for live-streaming videos or to facilitate video chats, so even though webcams can capture images and videos, they are more commonly used for these purposes. Cameras and microphones are typically included in webcam devices.
You can point, scroll, click, and swipe using a touchpad, often known as a trackpad. Laptops (no matter the brand) are commonly equipped with touchpads. A touchpad provides all the same functions as a computer’s mouse.

What are the output devices?
Computer output devices receive data from a host computer and then convert it. You can deliver this in audio, visual, written, or physical form, etc through a printed document. Computers receive data from input devices, whereas output devices deliver data to the computers.
Types of computer output device
The output devices come in three forms:
1.Audio display device
There are many types of output display devices, including monitors, screens, and other accessories. It is a device for displaying text, graphics, or video, as it is a standard display output device, but it does not have a TV or projector.
2.Audio output device
A device referred to as an audio output device plays audio both from internal and external speakers, including headphones via a 3.5mm jack. You can use Lightning, Bluetooth, or Wi-Fi. There is also a sense of music or soundtrack with the audio output.
3. Physical output device
The best physical output device in this category is the printer, which makes solid output in general. The printer can be a simple 2D printer that prints words on a sheet of paper. Also, they can complete objects using 3D printing.
Functions of output device
An output device transmits the computer’s response either visually (monitor), audibly (speakers), or through a media device (CD or DVD drive). Computer users can comprehend the answer the machine gives using these devices.
Importance of output device
It is necessary for computers to interface with other devices through their output devices. The information stored in a computer becomes valueless if it is kept there alone. However, although data is saved, it is usually transmitted to another computer with output devices or directly to an output device for further processing.
There are a variety of output devices, including screens, electric motors, vehicles, lights, speakers, and more.
computer output devices examples
Everyone should know input and output devices examples. Nowadays, It has become very significant. Everywhere you would need input and output devices.
Computers cannot function without their monitors. Computers are incomplete without them. Displaying all types of information visually on a monitor is one of the most versatile functions of a computer. Information is displayed both graphically and symbolically on the monitor. Using its screen, it can display all the information and data in Soft Copy format. The user can interact with the CPU via this interface.
Monitors are also called Video Display Terminals (VDTs) and Visual Display Units (VDUs). The monitor can display a variety of files, images, movies, texts, graphics, and tables in real-time.
In offices, printers are the most common and basic output devices. Data is taken electronically and printed on hard copy. Printing of images and text can be achieved through the printers. The most commonly used printers are inkjet and laser. The printer can print in color and black and white.
Data stored inside the computer is printed by the printer (text can be in text form). You can set the font size to be small or large depending on the size of the page. In offices, homes, and business establishments, printers print signs, office documents, and PPT presentations.
Data cables or only wireless connections are usually used to connect the printer to a computer. Many of the latest digital printers feature wireless capabilities such as Bluetooth, Wi-Fi, or the cloud. This makes printing easier.
Speakers output audio signals to a computer through hardware devices. An audio component of computers produces sound. This component is called a sound card, and it comes preinstalled with the computer.
Computer speakers produce a sound through the audio signal sent by an audio card in the computer. On many LAPTOPs, the keyboard already comes with an inbuilt speaker. Speakers on motherboards are known as internal speakers. When the computer produces sound in a louder way, an external speaker may be necessary.
Large-format items such as banners, brochures, and booklets can be printed using this device. Large-format items such as banners, brochures, and booklets can be printed using this device. This type of output device prints graphics in several different color formats with high quality.
Printing on cardboard, fabric, film, or other synthetic materials is possible with the plotter but not with the printer. It is possible to print T-shirts, backpacks, and other flexible clothing items and circular items, such as cups.
Printers are faster, more accurate, and less expensive than plotters. Engineers and Architects use plotter applications because of their need for accuracy.
A headphone is a device that enables you to hear any sound that comes from a device or computer. Using headphones, you can hear the sound on the computer, laptop, and mobile phone. With it, you can listen to the sound without disturbing anyone else. The US Navy invented the headphone in 1910.
Headphones or earphones are primarily used in crowds to listen to audio privately and avoid disturbing other people. Headphones receive audio input from the sound card (or any connected device) and output it as wave sounds.
Projectors are also output devices for multimedia. Multimedia projectors are miracles of technology, and they are multifunctional and beneficial. An image, video, or graphical content can be projected onto a wall using a projector. When used in a meeting/conference room, classroom, or even a hallway, a multimedia projector’s output can be viewed by a large crowd via a large screen.
It is a satellite-based system for global positioning. Any device can be located with its help. Today, almost every mobile device has a GPS. You can see your location. Locating, forecasting, and tracking are GPS’ main outputs.
The GPS consists of 24 satellites that the Department of Defense places in the orbits of the Earth.GPS was initially developed for military applications by the USA. Users around the world can leverage the powerful capabilities of this system.
Speech generating device
People with autism and hearing impairments can use SGDs to synthesize sounds to assist them in speaking and understanding. With a wide range of language options, the device serves as an alternative to existing audio devices since it can be adjusted to meet the specific needs of patients or children with speech problems.
With the key-guard, data can be input using tilting of the head or eye movements. Medical science has greatly advanced with the invention of this device.
A braille reader enables blind people to use computers more easily. This device uses the central computer to deliver the processed data in Braille so that it is readable by the visually impaired. Braille Readers convert the processed data into pins pushed against a flat surface as soon as they receive the processed data. Through this device, visually impaired individuals can run their fingers through Braille’s script and quickly understand what is being displayed. A variety of sizes are also available for this device, just as with other output devices.
Speakers and headphones can make use of the sound card by regulating the output of sound signals. Sound cards are typically installed on motherboards, as they are called extension cards. It is not necessary to have a sound card when browsing the web, watching a movie, listening to music, or participating in an audio or video teleconference.
Video cards are also embedded in the motherboard, similar to sound cards. Video cards create pictures and videos that can be viewed on a monitor. For faster, more specific designs, a video card is more essential. While a PC’s motherboard provides necessary video and illustration capabilities, it requires a video card for point-by-point designs.
