Binary Language
Today in techie club we learned about binary language. Binary language is the language that a computer uses for numbers. For example, we write the number fifteen, 15. In binary language 15 would be 01111. It is kind of hard to understand, but I will explain it later.
In binary language there are only two numbers. As you can probably guess, they are 1 and 0. We got cards and we put them in order. They started at 16 and then 8, 4, 2, and 1. They told us that the back of each card represented 0 and the front represented 1. At first we started with easy ones like 4. You turn over the card that has a 4 on it and leave the rest on the 0 side. Then we did harder ones like 11. 11 is 01011. Remember, the cards were in order as 16, 8, 4, 2, 1. So, 01011 would represent 08021. If you add all of those numbers together, you get 11.
After that, we learned how to add binary numbers. In binary numbers there is no 2, so if you have to add 1+1, it would be 0, carry the 1. For example, if you added 00001+ 00001 (00001= 1), you would have to put a 0 down and carry the 1 on top of the next number, which in this case is 0. Then, you would add 1+ 0, which of course, is 1. So the answer would be 00010, which is equal to 2.
Like I said, binary numbers can be very confusing at first, but after a while it gets a little easier.
