Input, output, and processing devices

Congratulations! You have been given the opportunity to be a computer teacher. The first lesson you must teach your students is all about input, output and processing devices! But there is a problem...you don't know anything about this topic. So your job will be that you will educate yourself all about these devices. Once you have done some research, you will then create a powerpoint presentation that you will share with your students to help teach them all about this subject.
