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 …

Now, let's look at a simple example of how input travels through a computer and becomes output. When you press a key on your keyboard, let's say the letter B, the keyboard converts the letter …

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 …

They may look different, but they all share the same underlying technology. The more we understand how that technology works, the more we can use the computers around us to help …

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 …

Computer memory isn't infinite, so there's a limit to how much data we can input before we overflow the memory. Computers also vary a lot in memory size, usually because of physical …

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 …

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

What's the purpose of having a logic circuit? Wouldn't the outcome always just be the final gate's outcome? So basically you could just input whatever you need for the last gate and that's it...
