Input and output devices are how we interact with a computer, basically, how we give it information and how it gives something back. Input devices are things like keyboards, mice, scanners, and microphones. They let us send data into the computer. For example, when you type or click, you’re using an input device to tell the computer what to do. Output devices do the opposite. They take data from the computer and turn it into something we can see, hear, or experience. Think monitors, printers, speakers, or projectors. A monitor shows what the computer is doing, and a printer gives you a physical copy of a file. The main difference comes down to direction: input brings info in, output sends info out. Some devices can even do both, like touchscreens, which let you tap (input) and see visuals (output) all in one. Understanding the roles they play helps you understand how the whole system communicates.
