1, DOS and WINDOWS are divided into two categories, which examine the basic knowledge of computers and the initial ability to use microcomputer systems. Mainly for people engaged in word and form processing, daily information retrieval and office information processing. It requires candidates to have basic computer knowledge, master a commonly used Chinese character input method, master the use of word and form processing software, understand the use of database application systems, and reach a certain level of proficiency. Qualified candidates can successfully engage in computer processing of documents, secretaries and daily office information in government agencies, enterprises and institutions, including foreign-funded enterprises.
2. Second-level examination of candidates' basic knowledge of software and hardware, as well as the ability to program and debug on a computer using a high-level computer programming language (QBASIC, FORTAN, C, PASCAL, FOXBASE). The second level is mainly set up for the examination of personnel engaged in the use of computer or database management software. It requires candidates to have basic computer knowledge, be familiar with the function and use of DOS, and be familiar with a high-level computer programming language or database language. Qualified candidates can engage in the general application and development of computer software.
3. the three levels are divided into class a and class b exams. The third class A examines the basic knowledge of computer application and the initial ability of computer hardware system development, and the third class B examines the basic knowledge of computer application and the initial ability of computer software system development. Class A is designed for hard engineers in computer application engineering. It requires candidates to have basic computer knowledge, master the working principle of microcomputer, assembly language programming and interface technology, and be familiar with the application of computer in real-time processing and measurement and control system. Class B is designed to test soft engineers engaged in computer application engineering. It requires candidates to have basic computer knowledge, master programming and software engineering methods, and be familiar with the application of computers in information management, numerical calculation or aided design. Those who pass the third level can successfully carry out computer software and hardware application projects and reach a certain level of proficiency.
4. Level 4 evaluates the necessary ability of computer application project or application system analysis and design. Candidates are required to have basic knowledge of computer application, principles and application knowledge of computer operating system, software engineering and database system, basic knowledge of computer system structure, system configuration and performance evaluation, basic knowledge of computer network and communication, and knowledge of computer application system security. Those who pass the examination can comprehensively apply the above knowledge and engage in the development of application projects (systems), that is, they have the ability of project analysis, design and implementation.
Level 1 examination
In fact, there is nothing to say about the Level 1 exam. Most people don't have to report this level, which wastes money and lives. Therefore, the author strongly recommends not to go through this stage. If you have to test this level, I suggest you learn WPS while you are familiar with commonly used software. WPS will become a separate examination subject in the National Computer Rank Examination (Level 1) in the future.
Level 2 examination
Level 2 exam is compulsory for most people. The content of the second-level examination includes two parts: basic knowledge and program design. Basic knowledge mainly includes computer basic knowledge, basic knowledge and operation of DOS, and basic concepts and operations of WINDOWS. This part will be introduced in detail in counseling books with a little knowledge level. As long as you study hard, there will be no problem. The concept and use of files, directories and paths in DOS is a compulsory part, so you should pay attention to it.
The most important part of the second-level exam is the program part. Master the basic knowledge of language, paying special attention to basic concepts and methods (selection method, bubbling method, etc.). ), and can understand the program given in the book. Generally speaking, if you can finish most of the after-class problems by yourself, everything will be fine. Language work should be done in peacetime, thinking more, practicing more, and getting on the computer more. It will be helpful to consider doing some small programs yourself (the pious eyes of others will make you feel valuable). The computer test of the second-level DOS exam includes three parts: DOS operation, program modification and programming. If your C language has a certain level, the difficult part is program modification. After all, it is difficult to understand the thoughts of strangers. Therefore, we should read more programs at ordinary times, and pay attention to conform to the specifications as much as possible when programming ourselves, otherwise it is easy to suffer. Of course, practicing computer more is the only way to get good grades. As for counseling books, Dalian University of Technology Press and Nankai Press are both quite good.
Level 3 examination
Level 3 is a more troublesome level. It has four categories, which can be roughly divided into two types.
The third-level PC is an assembler, and the other three types are C programs. If you are not particularly confident in yourself, generally do not apply for PC technology. After all, learning assembly language is a big burden, and it doesn't help to apply for CET-4 (CET-4 doesn't test assembly! )。 The other three mainly depend on their own interests. Relatively speaking, the database is a little more difficult (except for the Department of Mathematics). The four categories of level 3 have their own emphases, but the trouble is that they are all too one-sided for level 4, so they are of little help. Therefore, the foundation is relatively good, and direct examination of CET-4 can also be considered.
The written test part is level 3 difficulty, and the content to be memorized is much more than level 2. Attention should be paid to the mastery of basic theories and concepts, which is conducive to the formation of knowledge networks and reducing the burden of memory.
Due to the recent three-level reform, the counseling books published by various publishing houses are difficult to get close to the exam. In this case, reading more books is the best choice. Judging from the last two exams, the topics are also very close to textbooks (especially network technology, some textbooks are original words). The difficulty of level 3 computer test is not much higher than that of level 2 computer test. More complex parts such as file reading and writing, function calling and other common topics have been given, so testing is still a relatively basic and typical algorithm.
CET-4
Level 4 is the last level and the most complicated level of knowledge. It takes a little confidence and courage to apply for CET-4. After you apply for CET-4, it is almost inevitable that there will be questioning voices around you (when I applied for CET-4, the teacher told me that no one had ever visited our school). At this time, you must believe in yourself.
The number of people who passed CET-4 is really small (compared with CET-3), but it should be noted that the number of people who applied for CET-4 is also the least. The knowledge of CET-4 is huge (just look at that thick textbook), and the main difficulties are discrete mathematics and computer English. For discrete mathematics, it will be helpful if you have the opportunity to take the core course of computer science-discrete mathematics. Remember to do a certain amount of exercises! You can't raise the level with a bare backrest.
Computer English is not as difficult as expected, and there are only a few hundred commonly used words. It is almost enough to look at the English questions of the past five or six years. You'd better have a professional dictionary at hand. Most of the words can't be found on Wenquxing. Relatively speaking, English questions are relatively simple, as long as you know the words, it will be OK.
What is novel in the written test is the essay question. It is suggested that you buy a book with questions and reference answers over the years (published by the National Examination Center every year), study hard and master the answering methods. Fortunately, there are generally four essay questions, and you can choose the one you are most sure of. Because CET-4 has been held for many years, the counseling books issued by various publishing houses are relatively irrelevant.
The National Computer Rank Examination (Band 4) published by Dalian University of Technology Press is highly recommended. This book is close to the exam and has detailed answers, which will be of great help to pass the exam smoothly! Be sure to do the questions over the years (within 5 years), and there is indeed a certain recurrence rate!
CET-4 is similar to CET-3. There is only one programming problem. Be careful not to be nervous. Be sure to save it, otherwise it will become 0. At that time, some of my classmates in the examination room forgot to save files because of panic, which led to failing the exam in the afternoon.
Finally, we must have confidence in ourselves. I believe that even if only one person passes, that person must be yourself! At this time, you are half successful.
Computer examination memorandum
The first is the registration time. Although the university has four years, if you want to take the postgraduate exam (most people will take the exam), you have to prepare from the next semester of your junior year, so the time left for the grade exam is actually only two and a half years (four opportunities). Therefore, if you are a freshman, you should consider taking the exam in April next year. Because the national computer grade examination is aimed at non-professionals, the difficulty is not too high (of course not, otherwise listen to me). If your school doesn't have abnormal regulations such as compulsory level 1 exam, then skip level 1 exam resolutely and start level 2 exam (time is precious, don't waste half a year on meaningless things). In all fairness, secondary knowledge is very basic. As long as you prepare carefully (you have a whole winter vacation to prepare) (even if your computer foundation is poor), it is still easy to pass. Although you can get a degree certificate from the third-level certificate and the leapfrog exam is also allowed, I don't advocate applying for the third-level certificate directly (even if you have a good computer foundation). It's cool to pass the third grade directly, but it's quite risky. Once you make a mistake (which is very likely, after all, Level 3 is very difficult), you will have to take the exam with the students who have just passed Level 2. Unless your nerves are as thick as a sewer, the pressure will be great, and the blow to confidence cannot be ignored. If you have confidence in your computer level, you can consider skipping the three-level direct exam after getting the second-level certificate, which can balance risk and efficiency.
Another important issue is the choice of computer language. Learning C language is highly recommended. C language is not only clear in logic, practical and extensible, but also convenient for learning languages such as C++ and C#. If you have the ambition of a lion, you should choose C language. It should be noted that both CET-4 and Advanced Programmer Exam need C language.
See which one you suit, and you can take the exam ~!
