1.2.2. Keyboards come in many shapes and sizes. Also in many variations of key strokes depending on use.
2. Output Devices
2.1. Speakers
2.1.1. Allow data to be extracted from the computer. Speakers allow the user to hear the information that was previously input into the computer though the varying input devices
2.2. Monitor
2.2.1. In my opinion, the most important aspect of the computer. Monitors allow for visual display and out of the information stored within the computer. Without a monitor or other output device, it would be extremely difficult to use information stored or input into a computer.
