But playing in the end, what I got, get a confused, learning so many computer knowledge? What do you want to do so many operating systems? Can the computer really improve the efficiency of work? High-tech is really a productivity? I think these things are only suitable for combining some traditional companies to do. In the IT boundaries, it seems that the hype is more than the technology! Within the knowledge I have learned, I know that the Trium-winning winner will also sell their souls at the temptation of money. IT is the information technology or the name of the computer? Why is China's IT always around the computer? I am learning computer network, listen to the knowledge we have learned, don't say basic knowledge such as physics, talk about professional classes: Word Office Automation, AutoCAD, 3Dmax, Passcal, C, Java, Data Structure, Database , E-commerce, windows2000server, local area mesh line, network security ... There are still many courses I can't remember that I have learned. The data structure is my favorite class, but we are learning with Passcal, that is, a teacher, border passca border data structure (because the pseudo language is passcal), Word? I am using TEX typography, do graduation papers, not the education method of I worship Oxford. 3DMAX? I only know that Maya can take high salary in Shanghai. AutoCAD seems to be a special class of our school, no matter what professional must be repaired! Let's talk about Java with c? Is it necessary to learn in both basic education? And I learned PASSCAL, as if I told us that I learned the computer to be able to find a job. . . No, I listen to someone, some teachers said that the school is still teaching Passcal, and people of others are teaching C, more teaching VC, I can't sleep almost after listening. database? It should be said to teach SQLServer. I don't know how, we use the PB when we do a course design, the teacher writes the code on the blackboard called us to enter and debug. I am more lazy, CP has a hard-entered code, and debugging is free. E-commerce course? I remember that this topic is a research topic abroad. How can we become a good so-called e-commerce laboratory in our school, to buy things with our virtual currency, seeing the students of the students, 嘿嘿 Someone There are 5,000,000,000 shopping coins, I really doubt that they can really receive what I have to buy? Local area mesh line, this is nothing to say, I have forgotten the exam, I regret it. . If you don't listen to your tutor, let me make up the test.
