Fortunately, computers have come a long way since the 1970s, and we can now input data into them using a variety of easy-to-use devices. The most common input devices are the keyboard, mouse, …

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 …

A desktop computer has RAM memory, as the running applications uses the RAM to store data temporarily. A desktop computer also has a CPU, input and output devices, and a hard drive …

It's impressive that we can put together seemingly simple devices like logic gates to create CPUs that power complex devices like our phones, computers, and even self-driving cars.

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, …

It's impressive that we can put together seemingly simple devices like logic gates to create CPUs that power complex devices like our phones, computers, and even self-driving cars.

Every semiconductor device is non-linear (diodes and transistors) and they are used every day by the billions. Engineers have figured out how to use non-linear devices, and you will, too, as you continue …

For example, infants being raised by only their mother are more likely to learn the word “mama”, and less likely to develop “dada”. Among the first words we learn are ways to demand attention or food.

For example, I helped create the Windows operating system that runs on most personal computers. The operating system is a program with special abilities that let it control the other software on the …

Most of what you see on that green circuit board are inputs and outputs, like power, USB, microSD, HDMI, and GPIO (General Purpose Input Output ports, to connect to the electric wires of your …
