How long does it take a novice computer to learn as a network engineer?
Suggestion 1: Go to the bookstore to find books for the network engineer exam. You ask the clerk to help you find it. Achieve two goals: 1. You need to know what network engineers need to learn. 2. Can I read the network engineer tutorial directly?
Suggestion 2: If you can understand it, then I think one year should be enough. If you don't understand, it means that your foundation is not enough and you can't meet the requirements of the starting point. You need to learn the basics first. You can find some books about computer grading. From the first level, I think you should be able to reach the first level without looking. Then look at the second level. The second level requires you to master a programming language, but the requirements are very simple, and you don't need to master it in depth. Level 3 should have some knowledge of hardware. There are three subjects, one of which is network technology. You can focus on it. Level 4 needs a more comprehensive application.
I have learned about the network engineer certification exam before, and many people suggest taking the computer grade exam first. After at least level 3, you can start to study related courses of network engineers or software engineers. I think if you pass Level 3 (you don't need to take the exam, but you need to learn the corresponding knowledge), you should be able to understand most of the books of network engineers.
Suggestion 3: In English, I think that since your English is not good, it means that the step-by-step learning method like English textbooks is not suitable for you. You can learn some computer-related English in a targeted way. My feeling is that grammar is not very important, but sometimes you need to know some related words. For example, the computer pops up a dialog box with an error written in it. You know this is the wrong meaning, that's all.
Above, I temporarily thought of these.
In addition, you are good at ps, and you can make great efforts. Now people who are proficient in ps are no worse than those who are proficient in network technology.
What software should a network engineer learn?
After reading your results, I found that you, like me, belong to semi-network and semi-plane design. DW belongs to network language, but not to computer language. Then PS and FW belong to picture design. Flash, which combines PS and FW, belongs to two-dimensional animation. PE belongs to film post-processing.

What certificate do network engineers need to take?
At present, there are certifications from the Ministry of Information Industry, including Huawei, Microsoft and Cisco, which are more authoritative than Cisco. It is divided into three levels: CA, CP and CCIE (from elementary to advanced). But its examination fee is more expensive.
What courses do network engineers need to take?
To learn network engineer, you must have certain computer skills first!
Learning is a step-by-step process, so network engineers have too much to learn. Start with the network administrator (assistant network engineer), and then learn some knowledge of linux. I have taken the Red Flag linux Engineer Certificate, but the network administrator doesn't want to take it. I want to rely on the network engineer directly, and I also take the Le this year. I don't think the topics are too difficult, as long as there are many subnet masks and routers, because there is not much information about network engineers. As long as you buy some mock exam questions and exam questions from previous years, and look at the key points and break them one by one, you can apply for the online work exam in June 165438+ 10, because these things are difficult, take your time! I did well in the exam in May, but it must be a little hard to know. I'm still trying, and I hope you will, too! What's the problem? * * Work together!
What qualifications do you need to become a network engineer! What kind of knowledge do you want!
There is no academic requirement. I take the soft exam twice a year. Sign up for two 75 questions in the afternoon and pass 45.
What qualifications do network engineers need?
It depends on whether you apply for the national soft test or Huawei cisco certified. The former requires different academic qualifications for different levels, while the latter two have no academic qualifications. But looking for a job is an interview, and the company will have minimum academic requirements. thank you

What courses do you need to take to become a network engineer?
First, learn the principle of computer composition.
Then I studied the network theory.
Finally, take an examination of a person from a related manufacturer. If you use an O device based on CIS, take Cisco.
What should network security engineers learn?
As network engineers, do we really know what a network engineer is?
Then I'll tell you the basic qualities that a network engineer should have:
1: Familiar with computer theory and network basic theory, familiar with network technology system foundation.
2. Proficient in network equipment debugging technology, server debugging technology, basic application platform debugging technology or one of them. Mastering an after-sales debugging technology is a necessary skill for network engineers.
3. Proficient in network platform design, server platform design, basic application platform design or one of them. Being able to design corresponding network systems and application systems is an important sign of mastering pre-sales skills.
4. Good oral and written skills. In all stages of system integration, such as user communication, scheme and tender writing, tender presentation and answering questions, user training, and completion document writing, writing ability and eloquence are all important basic qualities.
5. High level of computer English. The higher the product level, the higher the probability of using English, which sometimes requires English listening and speaking ability. In some international bidding projects, English writing ability will be tested.
6. Good interpersonal communication skills and the ability to cooperate with others, and a sense of teamwork. A network engineer should be a person who is good at communicating with people and establishing good relations with them.
7. Be able to solve problems on the spot under pressure. In particular, when users encounter technical problems in on-site installation, debugging or after-sales fault maintenance, there are few available resources on site, so it is inconvenient to call for support, and users' eyes are more on the side. This environment is a comprehensive test of engineers' IQ, EQ, technical level and debugging experience.
8. Extensive knowledge. System integration involves a wide range, and network engineers should be multi-functional.
Eight o'clock is a necessary working quality and basic material for a qualified network engineer. I hope that the freshmen and sophomores in the computer department have a good idea! But if all the above conditions are met and can be well reflected in my work, I don't think I can be regarded as an excellent network engineer. Of course, there is still a long way to go before the top senior network engineers.
What is a real network engineer? The Internet era has arrived. As we all know, the highly electronic social life makes the Internet an indispensable part of people's lives. E-commerce, e-government and distance education have penetrated into every link of people's life, work and study. And all this needs a large number of network talents to support. It can be said that network talents are the darling of today. Network engineer has become one of the hottest occupations, so what kind of quality can be called a real engineer?
From the perspective of knowledge structure, network engineers must have a comprehensive theoretical framework. Network engineering and network maintainer are two completely different concepts. The latter only needs to be familiar with an operating system or a network-based software, and can handle this problem. Network engineers, on the other hand, require a clear grasp of the whole network and be able to deal with problems that may arise at any time. The network is very complex, and the possible problems involve many aspects. Without a complete knowledge structure, it is impossible to be competent for this job. For a simple example, the network is suddenly disconnected due to adjustment or upgrade, which may be caused by routing module configuration problems, fiber transceiver failure or proxy server stop service ... Only by mastering these software and hardware knowledge can network engineers find problems and solve them smoothly in a short time. There are many kinds of network engineers. I will take the general LAN design and administrator as an example. A qualified network engineer should have the following knowledge:
First of all, we must have a solid hardware foundation, including mastering the structure and performance indicators of hardware such as servers, routers and switch devices. When designing a system, the performance indexes of hardware are all factors that network engineers should fully consider. Not to mention maintenance.
Secondly, we should master the most commonly used network operating systems, such as Win2003 and Linux. Nowadays, it is possible to use a variety of operating systems to build a LAN. After all, mastering more can better deal with problems.
Third, we should master the configuration method of routing switching equipment. It can be said that the Internet is built by routers and switches, and qualified network engineers must be able to build local area networks by themselves. It is unthinkable without relevant knowledge.
