Like most English proficiency tests, there is almost no way to improve your level through surprise specialization or short-term training courses, and you can only rely on your own solid accumulation. Many friends ask how to review. Then let's try to discuss what materials are within our study scope, but it must be noted that this is mainly for the Networker exam.
The mainstream of examination materials is always books. Personally, I think most of these books are consulted by the school library except some of them are bought. Therefore, I strongly recommend that comrades with this condition make more use of this resource. After all, it is still an old saying: "Don't borrow or read books." If personal economic conditions permit, it is also a good choice to buy more good books. What's more, no one says the following books are absolutely good. The key is to choose according to personal circumstances. It is good to feel that it suits you; If you don't think it's appropriate, then no matter how many people say yes, it's rubbish for you.
Well, without delay, I will list the sources of the following books and other materials:
1, a tutorial for network engineers; It must be noted that as a guiding outline, it can make your network knowledge structure more clear and reasonable. Because the course does not completely cover the examination content, it is absolutely necessary to obtain other materials as a deepening and supplement of knowledge. The following recommendations are basically synchronized with the outline introduction.
2. Principle of data communication; Including the content of communication principle and switching technology, there must be one or two big questions in the morning, and it is not enough to just read the tutorial. You don't need to read this book too deeply. Even if there is no foundation, it is not difficult to read it once or twice, which can make you take a big step forward. This part of related content also includes "signal and system". I don't think it's necessary to be friends with hardware.
3. Network architecture and protocols; Just watch this part of the tutorial. In addition, as teaching materials and reference books, I suggest two books, both called Computer Network, which have been published in the fourth edition, except that one is from Tsinghua University Publishing House and the other is from Electronic Industry Publishing House. The author of the latter book is Xie Xiren. The knowledge points in the last book are introduced more deeply and widely, which is more closely combined with the Networker exam and more suitable for candidates with a certain foundation; The latter book is relatively easy to understand and suitable for beginners or people with weak foundation.
4. LAN technology; Read the tutorial first, and then find a CCNA English textbook to read it again. This has three advantages: it is deeper than the tutorial; At the same time, improve the level of professional English; Learn the basics of Cisco routers and switches by the way.
5, Wan Technology to see the tutorial; This part of ATM is the key point, and we need to find other materials to deepen it (because it is popular, it is as popular as Cisco). In addition, it is necessary to clarify the basic networking principle of WAN, and then understand the basic protocols used.
6. Network interconnection; Read the tutorial first. The knowledge of routing in the tutorial is not enough. It is recommended to have a Linux environment and look at the routing configuration of UNIX system. You don't have to look at all CCNP tutorials, just look at routing and switching, and Chinese is ok.
7. Network operating system; As above, just learn linux. There will be one topic in the morning.
8. Network management; The first part of LAN management is well done, which is an experience that every network administrator should be familiar with. The latter SNMP is not too deep, but it is almost enough.
9. Network security; This course is very conceptual. If you want to go deeper, you can have more perceptual knowledge of encryption technology (such as RSA encryption and decryption principle) by reading computer cryptography, but you don't need to go too far. If you have the conditions, you can also feel the concrete realization of authentication, authentication, access control and other technologies in win2000. I think there are two very important issues, access control and firewall, but these two years have not been tested. It is best to combine Cisco's learning to deepen them.
10, the content of the following chapters is not enough just to look at the tutorial. It is suggested to search online for relevant project materials and practical technical documents to supplement them. The practical knowledge and project environment involved in this part appear frequently in the afternoon exam questions, but generally speaking, it is an assessment of candidates' comprehensive application skills and knowledge ability. In short-let's see how well you have mastered the previous knowledge.
1 1, Linux course must be read, including the configuration of various network services (WWW, FTP), CGI is not very fashionable now, so you don't need to read it. In addition, if you have time, it is also very good to have a look at the network operating system.
12, network programming, as long as you have considerable C language ability, the higher the better, and C++ is not needed. In the LINUX environment, you can learn socket and read UNIX or Linux network programming in books. The UNIX network programming in the top post is the best I have ever seen. It is best to download this information from the internet, but some bookstores sell it, depending on your actual situation. I seem to have seen a book like this published by a railway publishing house in the bookstore. It looks good.
13, the online tutorial has a synchronous tutorial. It is good to do it once, but I feel that there is no essential progress. In addition, there is a network designer who focuses on analysis, and that book is even more useless (suspected of plagiarism). Real network engineering problems often require your comprehensive ability to solve problems by using your basic knowledge in all aspects. For example, there is a question about the routing table at 200 1 in the morning.
14. If you feel that professional English is lacking, you can find a computer English book from Tsinghua, but it is not specifically for online English. You can consider subscribing to an email from www.mcseguide.com CCNA, so that you can learn English and make a topic. Other computer English books on the Internet or English websites are all good. If you go to them yourself, you will surely have plenty of food and clothing.
15, it's helpful for you to practice more. It's best to be a network administrator in a unit. If you have no chance, try to create one. If time and money permit, it is best to attend CCNA training. The most helpless way is to accumulate theoretical knowledge like me, and to a certain extent, it is more than enough to deal with the practical problems in the exam!
16, learn more about some of the most popular new network technologies (such as WAP, CDMA, PHS, GPRS, etc. ), and the specific knowledge is best checked online.
17, we must make good use of network resources. There are many professional websites related to this field. It is suggested to print out some good knowledge points. Then, if you don't understand the knowledge points, you must use the search engine and enter the keywords you want to find, and you can find the relevant information.
