Surprise!! There is no quiz this week, hah..
This week, we learned about network. First of all, professor introduced three ways of connection, and they are roundly connected, centrally connected and all connected respectively. Then, Mr Heap explained the reason why there are a great number of issues about security and privacy in the Internet. In the end, he told us how to avoid personal information being stolen. For example, providing some personal questions in a survey before giving account information to owners. Using personal password to log in.
The last week is coming, and I hope everyone can get a great mark in final.

It's quite fun for having test although I am not sure that I do well in it. Actually I feel that I almost know everthing about how to run the program with definition, even if I will get only 50% during the test. That feeling is what I am talking about.
Before having test, I was almost insane about CPU. A great number of words need to be comprehended and copied down. Time always play a perfect role in terms of giving pressure so that I get ready for the test in midnight. At last, I am a little worry about the project of Wikipedia Part III, because I have no idea.

This week we continue to learn the binary system, and professor taught us how to deconstruct images and change color.
The most impressive still is the binary system, because it is not the same as decimal system which uses frequently in our daily life. This week we learned how to transform negative numbers and fractional numbers to binary system.
When it comes to change color, I regretted that I did not comprehend it before the quiz. I totally have no idea when I look at the quiz. How can I don't know anything about color. I held my pencil, and I cannot let it down. After asking Janet, I knew that those numbers stands for different colors, and we can change all points from one color into the other color with definition. At last, I will get enough preparation work before having quiz.
