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 …

Computers perform more than simple Boolean logic operations on input data, and they typically output more than a single binary digit. Computers definitely use logic gates for all their calculations, …

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 …

Understand hardware, software, CPU, memory, storage devices, and key characteristics of a computer system.

So how do all of these programs get on the computer in the first place, and how can the CPU run them all at once? To find out we'll have to take a look at the operating system.

How can the input of one computer become the output for another (and vice versa)?
