█ UNIX operating system at present, a large number of communication jobs are based on UNIX-like systems. Most of the communication existing network equipment use UNIX-like system as the network management and system operation platform. In addition to communications jobs, the increasingly hot cloud computing-related industry is also using a working environment that is basically UNIX-like.

Therefore, skillfully mastering the ability to use this kind of system is the most basic requirement for graduates majoring in information and communication, which is very important.

Specifically, first of all, we should be proficient in the use of relevant basic commands. Secondly, it is necessary to have the ability to install and configure this kind of system. Furthermore, you should have the ability to deal with common problems.

You can install a virtual machine (VMWare) on your computer and install centos,redhat,Ubuntu dozens of times. Then on these systems, I force myself to start from building basic services such as ftp, web, firewall, load balancing, gradually complete complex service functions, and try to make their own virtualization, containers, distributed deployment, kernel development.

In short, their own use of UNIX-like systems, and Windows should be as skilled.

█ Digital Communication Network all communication majors must be proficient in the basic skills of digital communication network, at least to the level of HCIP.

The basic deployment capability of small and medium-sized enterprise networks must be available. VLAN partition, networking design, and common data modification operations of digital communication equipment are all the foundation. Complex routing protocols (OSPF, BGP, ISIS), try to master, or at least understand what is going on and how it works.

To learn how to use numbers is not to become a net worker. In many cases, problems related to IP networking will be encountered in daily work. With basic knowledge of routing switching, you can solve many problems and save a lot of time.

Digital knowledge is also likely to involve terminals, as well as systems. Know how to count, which is beneficial to the related work of the terminal and the system.

█ programming language communication is not a computer software major, but be sure to master at least one programming language.

The basic job of a communications position does not force the use of programming skills. However, mastering the programming language and knowing how to program are of great help to an in-depth understanding of communications and cloud products. When communicating with R & D staff, you know how to program and be able to think according to the logic of programming, which will be beneficial (quarrels increase the probability of winning).

Any skill is the window to a new world. Program language is the window of the software world, and the future is the software world. Do you understand?

Moreover, programming is an efficient tool. If you know how to program, you can write your own tools to greatly improve your productivity.

In the past, at the beginning and cut-off, we envied those who could program, and sometimes wrote some simple scripts ourselves, saving a lot of time and energy. Those of us who don't know how to program can only work by hand mechanically or ask for help from others, and the efficiency varies greatly.

In addition to engineering projects, programming skills are also very helpful in daily work, which can improve daily work efficiency (quickly deal with some boring work), and even participate in the improvement of workflow and platform.

If you know how to program, you can also start a lot of sidelines and generate income for yourself (and greatly increase your job-hopping opportunities).

█ wireless technology to learn communication, whether it is to learn wired communication (optical communication) or wireless communication, all need to seriously learn the relevant technology of wireless air port. Coding and decoding, modulation and demodulation, encryption and decryption need to be learned seriously.

Choose at least one of 4G and 5G (I suggest learning 4G), carefully start with the wireless physical layer frame structure, send and receive end-to-end, and learn all patiently. To learn empty words thoroughly is to understand the principle of communication. Learning based on the actual technology of the industry is more specific and easier than simply looking at the textbook theory.

It is best to combine the operator's current network knowledge to learn, the information can be searched in the external network. The knowledge of this aspect of the school is too old, it is useless to learn, and it is out of touch with the current network. At present, many schools are still teaching program-controlled switching and GSM, which I think is a waste of time.

The █ PPT/Word/excelOffice three-piece set is a very important skill. Most of the Office skills used by college students belong to the fur level and are very superficial. Even if they are already in the workplace, 90% of people use only 10% of the features of Office software. And the lack of ability, seriously affected their own work efficiency.

PPT and Excel, you must study hard. Pay for the training course, it's definitely worth it.

PPT is the skill that communicators use the most, and it's probably the area where you spend the most time. Report to the leader, need PPT; to communicate with customers, need PPT; to train colleagues, need PPT; to attend industry meetings, need PPT;.

In fact, PPT essentially tests the design ability, aesthetic ability, expression ability, communication ability and thinking ability. It is not a technology, but an art. Sometimes, when you work hard for a year, it is not as useful as an PPT.

Excel is also broad and profound. Now it is no longer a simple table, it is a path to data analysis, python, artificial intelligence. This skill is very popular, and if done well, it can be used as a whole new career area.

█ photo drawing, audio and video processing photo level is very important, not to pretend, it is mainly a question of aesthetic and beauty creation. These days, if the basic photos are not taken well, they will be held back and despised at the critical time.

Drawing is also the case. Now there are many scenes to draw, and you need to know how to draw (composition, color matching), including network diagram and architecture diagram. This skill is very common.

If you don't study very hard, don't learn photoshop. Nowadays, many P-map tools and poster design tools are stupid, and the basic goals can be achieved.

Audio and video processing is an important additional skill. Although we usually seem to be engaged in communications professional work, but more and more contact with audio and video. Sometimes, leaders have the need for this kind of task, and if you are good at this kind of work, you will be looked at by the leader and colleagues first.

█ project management universities do not teach now, but project management is very important.

Studying project management doesn't really ask you to be a project manager. Project management is a way of thinking, the ability to teach you how to do a complex thing well. For people with project management thinking, doing things will be very comprehensive and scientific. For ordinary people, it is a blow to reduce dimensionality.

The same is true of product thinking. I suggest you find a course and study it carefully. It is not to make a product, but to make you think of others and to get rid of your student mind.

█ Financial knowledge Financial and financial knowledge is a necessary skill for people in modern society. However, in the face of science and engineering education, universities ignore this part of the training.

In a shallow sense, this knowledge involves your financial reimbursement. From a deep point of view, you do not manage money, money ignore you, in real life in many places, need financial knowledge, understand a little, it is not easy to be deceived. No matter how strong your earning power is and you don't understand finance, you may still be cut leeks.

Another point is that communications and cloud now involve a lot of engineering project implementation, and also require basic financial knowledge. There is also the estimated budget of the project, which is a blind spot for many science and engineering graduates. Many young people do not understand when they graduate, but they have to study now when they are at work, so they suffer a lot. It would be more helpful to learn a little in advance.

By the way, in addition to the budget estimate, it is suggested that we should also teach ourselves a lot of knowledge about engineering specifications and construction process, whether it is an engineering post or a technical post, which is very useful in the practical work of communications.

Well, I'm thinking of the above for the time being. It seems to be a few, but in fact, there is already a lot of content. It is very difficult to really master these areas of knowledge.

Taking the postgraduate entrance examination or engaging in professional research requires high professional knowledge (higher mathematics, signals and systems, digital signal processing). The skills I have mentioned today are mainly aimed at the employed people and are more practical knowledge.

To tell you the truth, with the exception of a few R & D positions, most young communications majors will not be exposed to high-end expertise when they enter the job. Sometimes, mastering some basic skills will be more helpful to your career development.

Especially for students with poor academic qualifications, instead of clinging to those advanced knowledge, it is better to lay a good foundation and aim directly at employment. For example, the aforementioned digital communication and programming are important additions to job hunting.

All right, that's all I have to say. Welcome to add!
