This video connects binary (0s and 1s) to real on/off electrical circuits inside a computer.
- How does an electrical circuit relate to the 0s and 1s of binary?
- What is a logic gate, in your own words?
- Why does combining lots of simple on/off circuits let a computer do complicated things?
Quick work-a-long
Words to know: circuit, on/off, logic gate.
Try it: Find one switch in your classroom or home (a light switch, a power button) and describe it as an "on/off circuit."
