NotesWhen you access the Internet on your device, it converts the information you’ve requested into binary code, the language of computers. Everything computers do is based in binary code, a series of 1s and 0s. When you click on this article, your request is translated into a bunch of 1s and 0s. If you’re using Wi-Fi, these 1s and 0s are translated into wave frequencies by the Wi-Fi chip embedded in your device. The frequencies travel across the radio channels mentioned earlier and are received by the Wi-Fi router that your device is connected to. The router then converts the frequencies back into binary code and translates the code into the Internet traffic that you requested, and the router receives that data through a hardwired Internet cable. The process repeats itself until you have loaded this article—or anything that requires the Internet. All of this happens at an unbelievably fast rate; most routers operate at 54 Mbps (megabits per second), meaning that when such routers translate and transmit binary data, 54 million 1s and 0s are taken in or sent out in a single second.

Activity 1
“Computer engineers call a single high or low voltage a bit, and it symbolizes one piece of information. One bit can’t symbolize much; it has only two possible states, so it can, for instance, be used to stand for only two integers. Put many bits in a row, however, and the number of things that can be represented increases exponentially.”

Look at the following light switch. Think of each switch position as ON or OFF. How many combinations of on and off can you make with these light switches? Show me the combinations below using the words ON or OFF.

Activity 2: BINARY TO LETTERS
CREATE YOUR NAME USING BINARY CODE--- YOU CAN USE SHAPES, COLORS, OR JUST 0 and 1. Do this on a blank sheet of paper or in PowerPoint and print it out. YOU CAN ALSO INPUT IT BELOW.
