Simply put, certification is a written proof that a person has a certain ability. As an individual, you can continue to learn according to the requirements of the certification, so as to achieve the purpose of having the certification qualification; as a recruiter, you can better recruit according to the certification level. I think this may be the basic function of authentication. However, with the application of certification in business, it has cast a veil of commercialization on what should be simple and simple certification. With the constant hotness of the computer industry and the constant demand for professionals, various IT certifications can be said to be a mixed bag.
So should you take various certification exams? Is it necessary? For this question, I think we cannot generalize and give an absolute answer. If you decide to take a certification, then before you make up your mind, ask yourself: Why should I take this certification? If your answer is because the certificate is very popular or popular now, to find a job, or even to show off. Then I advise you to dispel this idea of ​​textual research! Because the purpose of your research is not clear at first, what's the use even if you pass it? What's even more incredible is that some friends went so far as to recite the question bank in order to prove it. Imagine that you have such a purpose, even if you have passed the certification and been successfully hired by a certain unit because of the certificate. what's next? Are you qualified for this job? Can you convince your work unit to give you a raise? I think the answer is clear to everyone.
In response to this phenomenon, I can only say that the certificate is just a stepping stone. When we enter the enterprise, the certificate becomes a piece of waste paper, and the ability can finally solve the problem. In fact, when we go to textual research, what is important is what we have learned in the process of textual research. What we pursue is the process rather than the result. If you have learned a lot during the examination process, even if you fail to pass the certification in the end, you don't have to regret it, because your real goal has been achieved. On the contrary, if you successfully pass the certification with back questions, I don't think you have achieved much success. Therefore, for friends who want to take the IT certification exam, please be clear about your ultimate goal before making a decision, and do not blindly follow the trend.
Because partial certification has now become one of the standards used by some employers to measure the ability of applicants. As a result, various training institutions for certification have also sprung up. In fact, there is no need for us to participate in training just to pass certification. why? Simply put, many trainings are products of certification commercialization. Take Cisco certification as an example. We all know that there are three main levels, namely ccna, ccnp and ccie, and the closest to us is ccna and ccnp. I learned ccna by myself. I have only read a part of ccna. According to my experience, although ccna is very basic, it takes a long time to fully grasp it, including completing the experiment. , The specific number varies from person to person. However, for commercial interests, the standard training time for ccna given by Cisco is only five days, and the same is true for ccnp. Just imagine how it is possible to master ccna skills in just five days, let alone ccnp. Of course, some training institutions take into account the quality of teaching and will extend the training time appropriately. But through this incident at least let us see the drawbacks of commercial certification. However, I am not against those who are qualified to participate in the training. If the self-learning ability is not good, participating in the training is also a good way to learn artificial intelligence. After all, the teaching quality of some training institutions in Shenzhen is well-known.
Finally, I want to talk about my own learning methods for the Internet. In the beginning, because there is no foundation, learning the Internet is really a painful thing. Everything is difficult at the beginning. If you can persevere and put your head up, you must have unexpected gains. You will find that after you have the foundation, it will be easy in the next study. So how to lay the foundation? For beginners, the best way is to look more, repeatedly, and see the principles of computer networks; think more, think repeatedly, and think about how the network works at all levels. Only after you fully understand the principles of computer networks, will you be able to learn more advanced knowledge. Many friends don't like to learn the principles of computer networks, thinking that these things are just empty theories and not practical enough. In fact, this kind of understanding is wrong. Don't underestimate these theories. They will always be with you in your future studies and play a basic role. Just like the foundation of a building, it must be firm. In addition, what I want to say is that for those who have a foundation, we must coordinate the relationship between breadth and depth of knowledge. On the basis of taking into account the breadth, focus on the depth, try to do one specialization with multiple abilities, one proficient with multiple skills, this has always been my requirement of myself. Finally, I would like to remind friends in the technology industry that if conditions permit, it is best to pay attention to management knowledge, which is very useful for our future development. At the beginning of the debut, the knowledge system is best to be seven-point technical three-point management. If you rise to the management level in the future, the requirement will become seven-point management three-point technology.
Having been busy for so many days, I finally spared some time to write something, and that's it! The above is purely my personal opinion, I hope to share with you, there is something wrong, I hope that the majority of friends can correct me, and I will listen to them.
