Counting in Binary

This module uses a combination of discussion and participant involvement to learn about the differences between analog and binary representations of information. Since computers use a binary numbering system, participants learn how to count in binary.

The goal of this activity is to illustrate the basics of working with the binary numbering system.

You can view these interactive demonstrations using the free Mathematica Player.

Here is a good one that shows how computers can model physical systems:

Binary and Communication Systems

The purpose of this activity is to introduce students to the concept of binary coding as a language and its practical applications in digital and communication systems.This project is intended to give students a deeper appreciation for communication systems and an understanding of how binary symbols are used to transmit information.
