Some are used to enter alphabets, and also used for entering special keys and special symbols.

Some multimedia keys are used to play sound and videos.

The standard keyboard has 101 keys, but today, the keyboard comes with 102 and 124 keys for better and enhanced performance.

There are three types of keyboard

• Normal Keyboard.
• PS/2 Keyboard.
• USB keyboard.
• Wireless Keyboard.

3. Scanner

The scanner is also considered to be the input device of the Computer.

The scanner is used to scan any document like images, pictures, documents, and text on paper and later can be stored on a computer hard disk permanently.

There are 2 types of scanners

• Hand-Held Scanners
• Flatbed Scanners

4. Trackball

The trackball is a pointing device, just like a mouse.

The trackball usually is built-in with laptops and notebooks. They are used to navigate on the area of the screen horizontally, and diagonally also are free movers.

Fingers use a trackball to select, click, and drag files and folders from one location to another.

They are small in size, more often square in shape. It is very easy and efficient to use and can be installed in less space.

5. Joystick

The joystick is famously used for playing games and in CAD {Computer Aided Design}.

In the modern keyboard, a joystick is pre-installed.

The joysticks can move LEFT, RIGHT, UP, DOWN, and a push-button at the top.

6. Light Pen

The Light pen is a pointing device and one of the input devices that looks similar to a pen.

They are equipped with light sensors that are activated when it is touched or used.

It is used for choosing and drawing pictures; it sends a flag and PC, which distinguishes the cursor’s position.

7. Touch Screens

Touch screens are capable of displaying and retrieving data and information on the net.

Touch might be known as touching the screen with fingers. They can be detected by fingers or pen-shaped stylus.

8. Optical Card Reader (OCR)

OCR is a mechanical or electronic gadget or device that can translate images, pictures, documents, or manually written content into coherent machine shapes.

OCR also works like a scanner that can check documents, pictures, images, and composed content and can store it in memory, which later can be contrasted with the previously stored data.

10 Output Devices of Computer System With Examples

The Output Devices of a Computer System are electromagnetic devices that receive data or information from the computer system and convert the data into a human-readable or intelligent form.

Generally, the output can be obtained mainly in two distinct and different ways: softcopy and Hardcopy.

Here we will discuss and list some of the famous output devices of computers which are also known to be the parts of computers used by kids, younger people, and professionals.

• Monitors
• Touch Screens
• LCD Monitors or LED Monitors
• Printers
• Speakers
• Headphones
• Sound Cards
• Plotters
• Projectors

1. Monitors

The monitors are the most used output device of a computer system.

They are also known as VDU {Visual Display Unit}. These screens are huge, require more power, and need a lot of space for installation.
