Computers can take many different types of input, like the keyboard of a computer, the touch pad of a phone, a camera, a microphone, or a GPS, but even the sensors on a car, a thermostat, or a drone …

Explore the role of input and output devices in computer systems on Khan Academy.

This diagram visualizes that flow: In the next video from Code.org, a designer and CEO will step through the process of typing input into a computer and rendering the output on the screen. After the video, …

If the device's main purpose is to gather information for the computer, then it's an input device. If its main purpose is to let the computer communicate information to the user, then it's an output device.

The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which …

Computers need a way to manipulate those 1s and 0s, so that they can eventually do more complicated operations like calculating the 50th digit of π . Computers use logic gates to transform the 1s and 0s …
