  4. Metcalfe’s Law of Connectivity That the power/value of a network increases in proportion to the square of the number of nodes on the network. 2 Computers = 1 connection 3 Computers = 3 connections 4 Computers = 6 connections 5 Computers = 10 connections 10 Computers = 45 connections 12 Computers = 66 connections

  5. This is what 20 connections looks like! Image what a billion looks like! 100 = almost 5000 Connections! So, the more that join the internet the more useful the internet becomes exponentially!!!

  6. Morse Code

  7. Dashes and Dots Represent Letters, Numbers, and Punctuation

  8. Computers Use Binary Code

  9. DIGITAL! • DIGITAL – it means that ONLY {off or on/0 or 1} is transmitted. Not Waves, Etc. • So, a CELL phone converts you the sound waves of your voice into radio waves. • A DIGITAL phone converts the sound waves of your voice into 1’s and 0’s and transmits the Binary Code of 1’s and 0’s ONLY.

  12. Fiber Optics

  13. Fire a laser down the strand • The fiber is coated with a mirrored surface so that none of the light can escape even if the strand bends or flexes • Can be as thin as a human hair • Can travel for thousands of miles • Each strand can carry 10 billion pulses of information per second.

  14. FIBER OPTICS GOOGLE IS STARTING TO BUILD 100% FIBER NETWORK • 1,000’s of times faster than high speed • Download a Blue Ray in a few minutes!!! DVD in seconds

  15. Fiber Optics That Are Already Used in Homes

  16. LASERS CAN CAUSE BLIND SPOTS IN YOUR VISION!!!! • YOU DON’T FEEL IT OR NOTICE IT WHEN IT HAPPENS (UNLESS THE LASER IS INCREDIBLY POWERFUL!) LASER DANGER!!!!

  17. LASER DANGER!!!!
