What can you do with a computer science degree? Jobs,Salary

In today’s digital world, computer science has become an important subject that everyone needs to learn. 

Related knowledge and computational thinking skills are the most important for developing innovative digital technologies, understanding modern society, and obtaining relevant qualifications in this field.

What is computer science ?

  • English name: Computer Science
  • Abbreviation : CS

Computer Science (CS) is a discipline that systematically studies the theoretical basis of information and calculations and how they are implemented and applied in computer systems. 

It is often described as the systematic learning of algorithms that create, describe, and transform information. In layman’s terms, this profession is what we often call “code farmers“.

Computer science is a scientific and practical method for computing and its applications .

What does it mean?

This is a state of mind. This is thinking that can help you lead different plans and build different things. This is an attitude that you can teach and learn. Moreover, it takes time to learn.

Calculation is an act or process. Calculate an activity based on any goal, and you can also benefit from it, or the process of creating a set of algorithms, such as through a computer.

Its application is very extensive. The research it involves includes:

  • Data, data structure and algorithm
  • Principles of computer architecture-hardware and software
  • Methods of problem solving and design
  • Computer-related topics, such as numerical analysis, operations research, artificial intelligence
  • Language design, structure and translation skills

Computer science knowledge can also provide students with a foundation to lay career goals.

Branches of computer science

Generally speaking, there is no absolute field division within the computer profession. If we insist on distinguishing work, we can roughly divide it into ten categories:

1. Software engineering : mainly divided into software design, programming language and software testing. It belongs to the general direction of CS. There are many places for admission and a certain amount of scholarships. The job market is broad, but the salary is not too high.

2. Database : It is very related to the current cloud data and big data. After graduation, you can be a database management engineer, but you need a certain amount of work experience. The programming requirements are not high .

3. Computer network : The scope of study is relatively large, and the scope of employment is broad . Equipment vendors, operators and third-party software developers will all open relevant positions. The application competition is relatively fierce, and other majors can also apply.

4. Artificial intelligence : a comprehensive subject, which requires a higher academic background in computer science. It is difficult to find a counterpart job , but you can find a related job.

5. Computer graphics/multimedia : Intersect with artificial intelligence, computer networks and software engineering. Need to learn computer imaging, three-dimensional animation, network image dissemination, etc. After graduation, you can go to a game design company or a film and video production company.

6. Algorithm : Interdisciplinary, in addition to the academic background of computer science, it is best to have a certain background in biology, physics and chemistry. Many people will become programmers after graduation .

7. System architecture : This major is related to hardware and requires a certain academic background in digital circuits. It’s more tiring to learn, not just need to write code.But the jobs are easy to find, & equipment manufacturers need such talents.

8. Human-computer interaction : speech recognition and alphago are actually the products of human-computer interaction. This is an interactive discipline of computer science, behavioral science, ergonomics, and design. Work experience is more important when applying.It is so difficult to find counterpart job after graduation.

9. Computational theory : a theoretical subject. It’s not easy to find a job .

10. Information Science : Research and everything related to information.The number of the admissions is limited and it is difficult to find a job.

Science field

As a discipline, computer science covers the theoretical research and computational limits of algorithms, to how to implement computing systems through hardware and software

The CSAB (formerly known as Computing Sciences Accreditation Board), composed of representatives of Association for Computing Machinery (ACM) and IEEE Computer Society (IEEE-CS), established 4 main areas of computer science disciplines: computing theory, algorithm and data structure , Programming methods and programming languages, as well as computer elements and architecture. 

CSAB has also established some other important areas, such as software engineering, artificial intelligence, computer networks and communications, database systems, parallel computing, distributed computing, human-computer interaction, machine translation, computer graphics, operating systems, and numerical integration. Symbolic calculation.

Theoretical computer

Generalized theoretical computer science includes classical calculation theory and other calculations that focus on more abstract, logical and mathematical aspects.

Computational theory

According to Peter J. Denning, the most fundamental question of computer science is “What can be effectively automated?”

The research of computational theory focuses on answering this fundamental question, about what can be calculated, and what is needed to implement these calculations.

How many resources. In an attempt to answer the first question, recursion theory tests which of the various theoretical calculation models is solvable.

The computational complexity theory is used to answer the second question, studying the time & space consumption of solving a computational problem with a different purpose.

The famous “P=NP?” problem, one of the problems of the Millennium Award, is an open problem in computational theory.

Information Coding Theory

Information theory is related to information quantification and was created by Claude E. Shannon to find the fundamental limits of signal processing operations, such as compressed data and reliable data storage and communication. 

Coding theory is the study of codes and their specific application properties. Code is used for data compression, cryptography, forward error correction, and also used for network coding.

The purpose of studying coding is to design a more efficient & reliable data transmission method.


Algorithm refers to a well-defined calculation process. It takes one or a set of values ​​as input, and after a series of well-defined calculation processes, one or a set of outputs is obtained. 

Algorithm is an important field of computer science research, and it is also the foundation of many other computer science technologies

Algorithms mainly include data structure, computational geometry, graph theory, etc. 

In addition, the algorithm also includes many miscellaneous items, such as pattern matching, partial number theory, etc.

Programming theory

Programming language theory is a branch of computer science, which mainly deals with the design, implementation, analysis, description and classification of programming languages, as well as their individual characteristics. 

It belongs to the discipline of computer science, and it affects and affects mathematics, software engineering, and linguistics.

It is a recognized branch of the computer science and an active research field. Research results have been published in many academic journals, computer science and engineering publications.

what can you do with a computer science degree?

The question is what can i do with a computer science degree?

1.Should I start my own business?

I graduated from Stanford University and live in Silicon Valley, so I can’t escape the stereotype of “entrepreneurship”.Some of the people think that I am an “entrepreneur type.”Some people even made me their co-founder.

I have moved my heart more than once. The idea of ​​building a company from scratch is very tempting.

There no doubt that I will also learn a lot & not only about the problem I want to solve but also how to motivate people to work with me, how to raise funds, how to run an organization, how to sell products…

I have many friends They all have their own startup companies, and they have a lot of life content, but they are by no means boring. Moreover, the probability of them becoming billionaires is much higher than mine.

We often read the news about a certain 20-year-old entrepreneur raising millions of dollars, which makes us feel simple. “Even apps like Yo can get $1.5 million!” Someone once explained to me why I should start a business based on this.

But I have seen too many friends’ entrepreneurial lives. I know that this kind of life is very stressful, cruel and ruthless, and will be restricted by many external factors. Quite a few of my friends’ startups have failed.

Even though they are very smart & have great ideas,they have received support from well-known investors.

Whenever I feel bad,I will call these entrepreneurial friends and see them struggling hard,I will be very happy that I am not them.

I may be in the minority in this regard, but I think: starting a business for the sake of starting a business is unreasonable and a complete waste of time.

Before I had the following three things, I would not start my own company:

  • A problem that I hope to devote my life to solve.
  • Believe that you can solve this problem.
  • A co-founder I can too work with for a long time-neither of us will try to murder each other.

Currently, I don’t have any of these three items yet, so wait and see. I also think that working for others for a few years will make me better prepared for my own career-both financially and technically.
