Keyboard
A keyboard is an input device that allows someone to type in letters and numbers that they want, it is the main input device in most computers.
Computer keyboards are similar to typewriters but contain additional typing keys and is more modern.


Computer Mouse
A Computer mouse is an input device that is usually used in a personal computer, it is placed on a flat surface we move it and unfortunately it is moved on the screen.
Moreover it all works by hand control
Scanner
A scanner is also an input device, it is used to scan or copy information and images into a computer.
A scanner can be connected in many different ways but now the most common one used is a USB device.

A microphone is an input device it is actually very important because it can be used instead of a keyboard.
You talk in the microphone and you say commands for the computer to do what you want and it follows exactly what you say. I actually find it really helpful for disabled people.

Processor CPU

In computers, a printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper.
It can be connected to one computer and to more than one computer.

Speakers
Speakers are connected to a computer and it’s an output device. It is used to project out sounds and music that you choose, speakers usually come in different sizes they have volume buttons that you can make the volume higher and lower from.

Monitor
A monitor can be an input or an output device if it is a touch screen than it is both but if it is not like the one in the picture than it is only an output device.
All what you want is projected in that screen it shows you everything and it has a lot of settings so you can have it as the way you want.
