Binary calculation of computer

For the binary calculation, I learned it when I was in middle school. It was amaing for me at that time that everything can be translated into a series of "1" and "0". Anything you can type in a computer, it can be translated into numbers, and then the computer can give respond so quickly from translating those numbers into the languages we understand. And in the past, I only knew a little about how to translate base 10 numbers into binary numbers, but now I also get an idea of how to translate symbols and words into "0" and "1"!!!

This is the table we learned in the lecture, and it demostrates how we can use numbers to stands for symbols. I feel it is a lot of fun because maybe one day I can use this method to create some private code with my friends and nobady will understand us. :)))

And we also learned how to do binary addition and multiplication. Which is pretty much the same as base-10 addition and multiplication. So I did not find it is hard at all, but the result is really long so I need to be very careful when I am doing the calculation.

I love doing calculations but the history we talked in lectures were a little bit abstract. I am a visual person, for different parts of a thing I need to see the whole parts of this thing and see where they are setted. But for the lecture, I cannot imagine where the part is in the computer, so I I feel the lecture is kind of abstrct for me. And when I am answering some hard questions on the text about the functions this part has, I cannot figure out all of them.

But next time, I will download a picture from the internet, and I hope I can get a better understanding of all the lectures, and I will do well on the exam. :)

Thanks for Prof. Heap of giving such a good course to us. I will put a lot of efforts on this course.
