If you teach programming or computers, then you will want to take a look at nandgame.com. The site breaks computers down to the logic of zeros and ones, allowing a user to learn what’s going on behind the scenes. The site starts out with some higher level terms, so you’ll want to go over those terms with your students first.
The site was inspired by nand2tetris, which itself is available for free as an online course.
