There are some input devices that we are very familiar with, like digital cameras, microphones, and web cameras. Even some input devices that are less common are still used often today such as digitizers, scanners, and biometric devices. These devices take the information we have in that moment and upload that information digitally. For example, scanning a physical document uploads the information on paper and uploads it to the computer’s files.

Output devices include speakers, printers, and displays. Many of us use these often, as they can be easily accessed with a computer or other device. These devices take the information that the computer has and puts it into a more humanly tangible form. Printing, for example, is almost like the reverse process of scanning; it takes the information from the computer and puts it on paper using ink.

Finally, there are also input-output devices which can both take in and distribute information. One example is an audio headset, which is essentially combining the input of a microphone and the output of a speaker, allowing back-and-forth conversations live.
