Recently for my Computer Science we were given a mini project with CsUnplugged where the gave my team and I a topic -ours was error detection- and we had to teach our class about it. So what is error detection? Well to give a brief summary it starts with one computer transmitting data in a sequences of 1's, and 0's known as bits ,and as we know sometimes when the data is being transmitted it does not go as planned, and the data is changed. To recognize that the data has been changed is error detection. How it does this is a single row, known as parity bits is added to those 1's and 0's (bits). A single parity added to the row of bits allows the computer to detect where and when an error has occurred, if a bit has been changed and if there are an even amount of 0's.
Our team showed this through a comedic video- we thought if we used comedy it would be a way to engage people- and in the video we did a card game that represented bits, where we laid the cards out in a 6 by 6 grid. One side of the card was white, representing 1, and the red side represented 0. We had one person turn away, so they wouldn't see someone flipping the card, and when the turn back they had to figure out which card had been flipped. They would figure this out just like a computer would, by looking at the 6 by 6 grid and detecting which column had an uneven amount of 0's in it. Once they figured it out they would flip the card back just like how a computer would change a bit back. I think the most important thing I learned from this project is that you don't need a computer to learn and/or teach about computers. Here is my video if you would like to check it out! https://drive.google.com/a/nvusd.org/file/d/0BwBd7w4lRj2EbHF6TjlHeFdFblU/view?usp=sharing
