     We finished this term today!!

     This week we learn the definition of "flatten" and  "depth". Actually, it does not matter whether we really  understand what "flatten" and "depth" mean, because it will give us the definition of a code. Therefore, we only need to comprehend the definition and use the pattern in each instruction.

     Good luck on the final. Yeah!!

     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.

     Reading week is coming and I don’t have any planning. The girl who has class with me dropped this course, so I also consider whether I should give up this course due to the low mark of last test. After talking to my mum, I still decide to keep working in it.

Last week we learn binary system. It is not that difficult because there are similar between binary system and decimal system, and we started to use decimal system in general mathematics when we were young. However, two states is the smallest so that binary system is the most easily designed in computer science. Decimal system is multiply each digit by the appropriate power of 10, and binary system is multiply each digit by the appropriate power of 2. For example, 1011=1*1000+0*100+1*10+1*1 in decimal system; 1011=1*8+0*4+1*2+1*1 in binary system. It is not that complicated. In addition, I found that the video is very useful for comprehending contents and finishing quiz. ;)

     I forgot to update slog because I got 2 tests and 3 assignment last week.   From start to now, this course is quiet easy, but I still cannot comprehend completely due to my negative attitude of studying. After finishing CSC test, I felt horrible. It is obvious that professor only wants to check the basic thing about our learning contents and details in this test instead of difficult things . However, I still lost a number of marks which should not lose. It feels bad. Maybe I should recognize that I put less attention than I'd expected. My major is mathematics, and I always believe that there is a great number of relationships between computer science and maths.
    No matter how bad today, tomorrow is still wonderful.

     This is the third week of this semester, I feel that time passed so quickly because I really enjoy this course. This week we learned something about the history of computing devices. A long time ago, computing devices are not as smart as they are today. At that time, they can only do some simple computing. As the time goes, some computing devices, however, are invented to process complex computations and finally the mass produced computers whose name was UNIVAC appeared. It is said that UNIVAC was the first computer in the world and it is the best invention in the recent 100 years. This history was miraculous and it changes our life. We also learned how to rotate an object with codes, although I was not clear. Next week we gonna have a test, and I believe that I can handle it. J
