Top ten popular majors at present?

Computer major can be said to be an absolutely popular major. This major type includes computer science and technology, software engineering, information security, big data and so on. How to choose these majors? What's the difference after reading them? Many parents can't have such in-depth knowledge to understand the connotation of every major, so there is no way to tell which major is better. Bian Xiao will give you an in-depth interpretation from the aspects of learning content and difficulty, employment direction, salary and treatment.

First of all, the work content of these professional students after graduation may be related to the apps we see on mobile phones, such as QQ, WeChat, watermelon video, Tencent video, today's headlines, Meituan, Baidu map and so on. What does it have to do with these applications?

Computer science and technology

The main courses of this major are mathematics, physics, computer programming, electronic circuits and operating systems. You can take some courses related to embedded system, visualization technology, bioinformatics and artificial intelligence. Its concentrated practice links include Java development, assembly language, Weibo technology, database, APP development and it project practice.

In fact, the core courses of this major are data structure, computer composition, operating system, database principle, computer network and software engineering, and then you can find a high salary by learning a computer language that you are very proficient in. Its core competence must be programming, and it can develop projects, such as developing an APP, making an information system and developing a small program. After graduation, the employment direction is to go to Internet companies or software companies, or to corporate information departments in other industries. Undergraduate students earn 30 million to 40 thousand, and their monthly salary is very high. There is also a big gap. Students with high salaries are very capable, not strong in schools. There are also many phenomena that 985 universities can't run double non-undergraduate programs.

Therefore, the computer major is suitable for those who don't like reciting, and even English is not very good, but they can learn math and physics well without learning, and they love to do it, and they still have the spirit of asking questions. Such students are waiting for you to study computer science with high salary. Those students who are particularly good at English and are not very flexible in how to learn math should apply carefully. Students who usually study by memory rather than reasoning should also apply carefully. Although your major is popular, your salary may not be high.

Some parents may say that even if my salary is not high, it is higher than many other majors, and it may be one or two thousand higher, but it doesn't make sense. Have you ever heard that a 35-year-old engineer will face a career change if he is not renewed by some big internet companies, but some jobs become more and more popular with his age. For example, they study medicine, become the backbone at the age of 35, and then study computers. This time has reached a spent force, so the logic of learning computer must be to earn income from other jobs for two or even three months every month, otherwise it will be very uncomfortable to learn computer without talent after the age of 35.

software engineering

The basic courses of software engineering learning are not much different from computers, mainly mathematics, physics, computer principles and computer networks. Professional core courses include software architecture, software project organization and management, software engineering and other courses. Professional elective courses can still choose courses such as cloud computing, machine learning, artificial intelligence, and even some courses such as big data processing. The links of concentrated practice are mainly engineering research and practice and engineering practice. Project practice is simply to develop a project, which can be an APP, an information system or a small program.

The study of this major is not much different from that of computer, and they are close relatives. Core courses include software engineering foundation, software architecture, software project organization and management, etc. After graduation, the employment direction is similar to that of computer major. Employment units are like large enterprises represented by Tencent and Ali. If you can't learn well, you can only write programs in some medium-sized or small companies. If it is suitable for computers, it is suitable for software engineering, and the income is similar. If you learn well, you can go to work in these enterprises listed below. There are so many enterprises that they can get high salaries.

information security

The basic courses of information security are similar to computer and software engineering, including mathematics, computer network, data structure, circuit and physics. However, compared with computer and software engineering, his core courses are much worse. The core courses mainly include operating system and security, cryptography and application, software security, network security and compilation principle. There are many specialized courses related to security, such as information content security, information security engineering and management, computer forensics, information hiding technology and so on. In elective courses, you can still choose Java language development, algorithm analysis and design, WEB technology, parallel computing, embedded human-computer interaction and artificial intelligence. Java is an essential language for computers, but it is only an optional course for information security.

The link of concentrated practice is the application of basic practice, network and home network, computer principle and assembly language, and then the practical courses related to information security. Compared with computer science and technology and software engineering, its core courses have changed greatly, mainly learning a series of security-related courses, such as cryptography, software security, network security and so on. The most suitable companies for employment after graduation are Ali's security field, Lumeng Technology, Anheng Information, AsiaInfo Security, Shen Xin, Chianxin, Huawei, Xinhua San, Tianrongxin, Tencent Cloud, and either go to large companies to do security-related business or go directly to such companies to do security. If you learn security well and have good skills, you can do network security-related technology development or maintenance in these companies. However, if you practice your programming skills well in the university, you can also grab the jobs of students majoring in computer science and technology and software engineering and do programming work, so that your employment will be wider.

The learning difficulty of this major will have higher requirements for mathematics. If you want to get a good job in this major, the first thing is to learn a detailed safety course, and the second thing is to improve your program development ability. The income after completing this major is similar to that of the first two majors. If you can grow into an expert in the field of security, your income is very high.

Data science and big data technology

The basic courses of this major also need to learn data structure, database, operating system, computer network, mathematics and electronic circuits. In mathematics, the study of scientific calculation and mathematical modeling will be strengthened. Mathematics learning is a little more difficult than the above three majors. Professional core courses include algorithm analysis and design, machine learning, large-scale database technology, visualization, big data collection and fusion, data warehouse, distributed and cloud computing, intelligent search and engine. Python data processing and R language data processing and conversion are added to the specialized courses, and Java programming, WEB programming and mobile APP application development can be selected, such as Java\WEB mobile application development, which is a compulsory course for computer and software engineering, but in big data.

Centralized training mainly includes data processing and comprehensive application practice of big data. Big data science and technology is very different from the first three majors. Its core courses are more inclined to algorithm analysis and design related to big data, machine learning, distributed system and cloud computing, big database technology, data warehouse, deep learning and visualization. After learning, I can mainly do data collection, data storage, data analysis, data visualization and application. Therefore, in addition to learning some basic programming techniques, there will be many courses in the direction of mathematical models, and courses related to large-scale data storage will also increase. Programming will focus on Python and R language, but both languages are relatively simple.

Graduates of this major are often much worse than computer science and technology and software engineering in programming ability. They will have a deeper understanding of the direction of mathematics and big data storage, but in terms of employment, because ordinary small enterprises do not involve a lot of data, and large enterprises have high recruitment requirements for big data talents, master schools are preferred, so students with poor grades are recommended. Students who can only take one or two exams should try not to choose this major, or choose this major as computer science, technology and software engineering. The core of the university is to improve your ability of Java programming or Python programming, or to develop software-related projects, so that you can compete with computer and software engineering students for employment, otherwise it is really difficult for you to find employment after studying this major.

At present, I have contacted a large number of students in this direction. Although these students have certain big data thinking and certain mathematical knowledge, they are still rejected by many enterprises because of their lack of strong software writing ability, or they can only find another job. If your score is high enough and your school ranks high, you can choose with confidence, and you have to prepare for the postgraduate entrance examination and then go to a big company, so your salary is also considerable, even higher than that of students majoring in pure software development, software engineering and computer science and technology. You can go to some big companies to do big data.
