What are the parts of a computer?

At a high level, all computers are made up of a processor (CPU), memory, and input/output devices.
Each computer receives input from a variety of devices, processes that data with the CPU and memory, and sends results to some form of output.
This diagram visualizes that flow:
An illustration of the components of a computer. A keyboard is labeled as "input" and an arrow flows from the keyboard to two components labeled as "CPU" and "memory". An arrow flows from them to a monitor labeled as "output".
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, we'll review each of the components and practice what we've learned.
