The paper test for IT position at CCB headquater

It was a really bad day. Seriously, the computer principle, C++ language, SQL database, and so on. I felt very sorry to have got up that early to catch the test.
Out of doubts, the competition was very fierce. And the computer realated questions really made me sick!
Hence, I am going to sum up some points of this kind of paper.
The range is mainly focused in the following aspects:
1. the principle of computer: the CPU, Register, Memory, outer Memory and so on.
2. the software engineering related: all kinds of program: c++
3. data base: SQL language and so on.
4. Network, very little part

Hope that there comes a miracle helping me to go to the next round!
