Binary
There are only 10 types of people in the world: Those who understand binary and those who don't!One of the fundamental computer science concepts is that everything we do on a computer really comes down to just two numbers: 1 and 0. All data, no matter if it is text, music, videos, or something else is represented by a multitude of 1's and 0s'. Just like when a light is switched on or off, the circuits in a computer are either in an on/true (1) state or off/false (0) state. Even though this sounds simple, it can be a concept that is hard to wrap one's head around. Here are some activities to introduce students to the concept of binary:
