Having a good understanding of how binary works is fundamental to knowing many other aspects of how all digital technology works, including computers, networks, PDAs, cell telephones, TVs, etc. Rationale Objective: to realize the importance of the binary number system and convert numbers between base-ten and base-two number systems.
Processing Information Electricity is either on or off. 1=on 0=off

Bits and Bytes
Summary Bits are binary digits. Each bit can hold the value 0 or 1. Bytes are made up of 8 bits each. Binary math works just like decimal math, but each bit can have a value of only 0 or 1. Microchips use transistors to process the information (on and off electrical currents) so the computer understands it.
“There are only 10 kinds of people in this world, those who understand binary and those who don’t.”
