There are many other ways a computer could output data. As long as the output device can interpret a stream of 1s and 0s, it can turn that data into anything - headphones output sound, printers output …

For example, a speaker will play sound and a 3-D printer will print an object. Output devices can also control physical motion, like a robotic arm, the motor of a car, or the cutting tool of the milling …

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.

There are many other ways a computer could output data. As long as the output device can interpret a stream of 1s and 0s, it can turn that data into anything - headphones output sound, printers output …

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 …

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 …

Let's solve some problems to better understand input and output devices.

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 computer.

The logic gates that we've presented here are abstract representations of real devices. A logic gate describes any device that can take in values of 0 or 1 and output a 0 or 1 according to its truth table.
