If you send the chat text to the other party and the other party sees it, this is the network. As the name implies, countless computers are connected into a huge network.
How to manage this network, how to plan the route of data transmission, and how to deploy network cables and network equipment? This is network engineering.
This is a subject that needs the combination of software and hardware, that is to say, students of this major should not only learn basic theoretical knowledge, but also learn software-related knowledge and hardware-related knowledge.
You can learn very shallow, or you can learn very deep, and there is basically no bottom. If you can go deep into a certain field and be a top figure in a certain field, it is easy to make an annual salary of one million.
What do you major in network engineering?
Most universities in China mainly study basic knowledge and theoretical knowledge, and a few are practical skills.
For example, the main courses of network engineering major in an ordinary undergraduate university are:
Advanced mathematics, introduction to linear algebra, discrete mathematics, high-level language programming, computer composition principle, interface and communication, computer system structure, network management technology, assembly language programming, data structure, computer network, database system principle, data communication technology and application, information security and network security, network engineering and networking technology, etc.
Most schools have these courses, and there are some differences in professional courses in different schools. However, computer network is a compulsory course. As long as it is a network engineering major, it is also the most important course in this major. If you don't learn this well, please don't say that you are a network engineering major after graduation, so as not to embarrass the school.
In addition, discrete mathematics is also necessary in the basic theory course, so it is best not to fail the course, so as not to affect your postgraduate entrance examination and postgraduate study.
There are also courses in network engineering and networking technology. There will be experimental or practical courses, so be sure to listen carefully and do experiments seriously, because this course is closest to your future work. If you don't learn well, it will be difficult for you to be competent for your future work.
This course will talk about the hardware knowledge of many manufacturers, such as Cisco, Huawei, H3C and so on. The equipment of these manufacturers will definitely be encountered in your future work.
If you understand clearly and thoroughly, you can get twice the result with half the effort in future work, and it is easier to work in big companies like Cisco and Huawei.
If you can't learn this course well, then you may really have no interest in network engineering, so I suggest you change careers.
