What is computer science?
Computer science, or CS, is a practical discipline that focuses on the systematic study of the theoretical foundations of information and computing and how they are implemented and applied in computer systems. It is often described as the systematic study of the algorithmic processes that create, describe, and transform information.
CS can be roughly divided into the following areas:
- Hardware: digital circuit, integrated circuit, memory, various hardware design and verification methods, etc.
- System: computer framework (instruction set, serial, parallel, grid, cloud, etc.), embedded, real-time systems, etc.
- Software: operating systems, virtual machines, programming languages, tools and methodologies for software design/development/validation, etc.
- Network: computer network framework, protocols, components, path algorithms, performance analysis, etc.
- Computing theories: computability, formal languages and automata, cryptography, logic, algorithm analysis, etc.
- Computing methods: numerical computing, symbolic computing, parallel computing, computer graphics, artificial intelligence, machine learning, etc.
Why study computer science?
Many students choose computer science for its high earning potential, various job opportunities, etc. Here are five reasons to study computer science.
1. The needs of social development
Now the world has entered a stage of rapid development, mainly relying on high and new technology to promote social progress, among which computer science is almost an important discipline throughout. Both artificial intelligence (AI) and space technology are inseparable from computer science. Learning computer science well can have many positive impacts on the world.
2. Multiple job opportunities
Because the development of modern society needs computer science, all walks of life will recruit computer science graduates. Therefore, if you get a computer science degree, you will have more job opportunities than other majors.
3. High salaries
Computer scientists are in demand, and their salaries reflect it. Computer science graduates have high starting salaries and good job prospects. Their average salaries are significantly higher than those of graduates from other majors.
4. Develop various skills
In addition to the ability of using computers, studying computer science can also develop other skills, such as critical thinking, problem-solving, analytical skills.
5. Transferable CS knowledge
The necessary skills for computer science are also valued in other careers. The skills of solving problems and analysing data are vital in many other fields, such as management and marketing.
What Computer Science degrees can you study?
Computer science usually appears on the list of majors in two colleges — the College of Arts and Sciences and the College of Engineering. The CS under the College of Arts and Sciences will only have an MS or Ph.D. degree, and the CS under the College of Engineering will have an MS or Ph.D. degree and an M.E. degree.
When applying for computer science, students should pay attention to which course is in the professional list of which college, and what kind of degree type is it. Below is list of some computer science degrees.
- Computer Science BSc/MComp
- Computer Science (Data Science) BSc
- Biology and Computer Science BSc
- Computer Science and Electronics BEng
- Computer Science MEng
- Information Engineering MEng

Computer science specialisations
Computer science is a very broad subject that includes many fields. If you choose to further study or enter the workforce, most computer science graduates are also proficient in a field.
Below is a closer look at some of the most popular computer science topics.
Programming language
Generally speaking, a program is a set of instructions written in a particular language (C, C++, Java, Python) to achieve a particular task.
A programming language allows programmers (developers) to communicate with computers. It consists of a set of rules that allows string values to be converted into various ways of generating machine code, or, in the case of visual programming languages, graphical elements.
Internet of Things (IOT)
The Internet of Things, or IoT, is a network of interrelated devices that connect and exchange data with other IoT devices and the cloud. IoT devices are typically embedded with technology such as sensors and software and can include mechanical and digital machines and consumer objects.
These devices encompass everything from everyday household items to complex industrial tools. Increasingly, organizations in various industries are using IoT to operate more efficiently, deliver enhanced customer service, improve decision-making and increase the value of the business.
Cybersecurity
Cyber security refers to any technology or measure used to prevent cyber attacks or mitigate their effects. Cybersecurity aims to protect the systems, applications, computing devices, sensitive data, and financial assets of individuals and organizations from simple and indelicate computer viruses, complex and costly ransomware attacks, and everything in between. Cyberattacks can disrupt, damage and even cripple businesses, and the cost to victims is rising.
Artificial intelligence
Artificial intelligence (AI) is a technology that enables computers and machines to mimic human intelligence and problem-solving abilities. AI can be used alone or in combination with other technologies (e.g., sensors, geolocation, robots) to perform tasks that would otherwise require human intelligence or human intervention. As a field of computer science, artificial intelligence includes (and is often mentioned together) machine learning and deep learning. These disciplines involve the development of AI algorithms modelled on the decision-making process of the human brain that can “learn” from available data and make increasingly accurate classifications or predictions over time.
Algorithms
In mathematics and computer science, algorithms refer to a defined limited number of steps or sequences that a computer can perform. It is often used in computing, data processing, and automated reasoning. Algorithms can use conditional statements to shift code execution through a variety of pathways (known as automated decisions), derive valid inferences (known as automated reasoning), and ultimately automate.
Human-computer interaction
Human-computer interaction is a discipline that studies the interaction between systems and users. Systems can be a variety of machines, or they can be computerized systems and software. The human-computer interface usually refers to the visible part of the user. Users communicate with and operate the system through the human-computer interface. As small as the play button on a radio, as large as the dashboard on an airplane, or the control room in a power plant, are all examples of human-computer interaction.
Computer science entry requirements
Each university has different entry requirements for computer science courses. Generally speaking, the College of Arts and Sciences requires students to work hard in language, and the College of Engineering has specific requirements for students’ undergraduate background and research experience.
The UCAS points required to study a computer science degree range from 80 (CDD at A-level; MMP at BTEC level) to 144 (AAA at A-level; DDD at BTEC level). The table below lists the different requirements for each specific test.
