WHY ARE THEY NEEDED?
For the system to work there is an input and an output. So if you use your keyboard to enter a letter then the computer will process the inputted letter then output it on the screen
Contents
TYPES OF INPUT!
Keyboard Mouse Microphone Scanner (The two orange high lighted ones
are very important) These are need as if you didn’t have them then you wouldn’t be able to control the computed. So without the keyboard you wouldn’t be able to type any words and without the mouse you wouldn’t be able to click on anything so like a web link or to open a file. (click the links for more information)

THE NEED FOR THE KEYBOARD
A keyboard is needed so you can input letters and numbers into the computer. So if you didn’t have a keyboard then you wouldn’t be able to write anything and search anything on the internet as you wouldn’t be able to type. So without the keyboard the computer system would basically be useless and only be able to play games like solitaire.

THE NEED FOR THE MOUSE
The mouse is needed so you can click links when doing a web search, when trying to access an app or when clicking anything on the screen. So without the mouse it would be 50x harder to click links as you would have to navigate around with the arrow keys and enter the website with enter.

TYPES OF OUTPUT!
Printers Speakers Monitors (The two in orange are
important) Without these you wouldn’t be able to hear a video that’s is on the internet or see the video and if you didn’t have the monitor then you wouldn’t be to use the computers as you couldn’t see what's going on. (click the links for more information)

THE NEED FOR SPEAKERS
Speakers are needed so you can hear what's playing from the computer. Without them you wont be able to hear what's playing and you will have to use subtitles in order to understand what's going on. Also it will make your life 10x easier if you can hear videos from the computer screen.

THE NEED FOR A MONITOR
A monitor is needed so you can see what's going on, on your screen, so that is what lets you see what you're pressing. This is probably the most important part of the computer (along side with the computer case/tower that powers the whole computer). Without it you wont be able to see what's going on with the computer and you wont be able to control the computer.

AUDIENCE
The audience for these products are everyone who use a computer. So old, young, male or female. Every computer needs an input and output. Without an input you cant control the computer and without an output you wont be able to see or hear anything on the computer.
