WHAT IS COMPUTER SCIENCE?

Computer science is the study of computers and computing as well as their theoretical and practical applications. Computer science applies the principles of mathematics, engineering, and logic to a plethora of functions, including algorithm formulation, software and hardware development, and artificial intelligence.

Computer science is the study of algorithmic processes, computational machines and computation itself. As a discipline, computer science spans a range of topics from theoretical studies of algorithms, computation and information to the practical issues of implementing computational systems in hardware and software. 

BRANCHES OF COMPUTER SCIENCE

Here are some of the specializations that you can consider for your computer science degree.

Computer and Network Security

In this field, CS experts address software vulnerabilities and mitigate security risks. Coursework for this specialization typically includes topics such as database management, advanced operating systems, cryptography, and advanced encryption strategies.

Mobile and Web Computing

Academic programs in this field may focus on broad, theory-based applications of networking protocols and other aspects of systems design. Other programs will focus on the creation of websites or mobile applications with an emphasis on interface design.

Human-Computer Interaction

This concentration prepares students to design and create the next generation of computers and technology. This might include moving beyond the traditional model of a keyboard and monitor to any number of other interfaces. Programs in this concentration often include coursework on design thinking and user studies.

Software Engineering

Programs in software engineering or software theory generally place a heavy emphasis on programming languages for a variety of uses. These programs typically highlight collaborative teamwork and software security. Students in this concentration will take courses on computer systems, compilers, and databases. (We cover software engineering as its own discipline.

Bioinformatics

Bioinformatics focuses on the intersection of computer science and biological science. Programs in bioinformatics will prepare students to mine and interpret biological data. This specialization often includes applications of technology in medical contexts, such as genome sequencing and computational biology.

Information Management and Data Analytics

In this field, students will learn techniques and strategies to store, organize, and analyze massive data sets. Topics for coursework in this field generally include algorithms for data mining, database architecture, and distributed systems and networking. While data analytics is a subtopic of computer science, there are also degree programs specifically for  big data

Artificial Intelligence

The field of artificial intelligence incorporates topics such as probability and modeling, robotics, logical reasoning, natural language processing, and machine learning. Applications of AI include autonomous cars, data mining and analysis, and intelligent tutoring systems (ITS) for teaching students.

Student reviews of top computer science schools

Although rankings are a great resource to identify top universities and colleges worldwide, they don’t always tell the full story. That’s why the opinions of students who graduated or are on their way to graduation are often more relevant.

They have hands-on experience with the academic environment, the university staff, the courses, and allow you to understand better what you can expect from studying at that institution. Check out a few reviews from students who took courses at some of the best computer science schools in the world:

ETH Zurich

“Teaching methods were solid enough; the library and assistance from the staff in study matters were also great. All this sums up to deliver ETH’s world ranking. As long as academic excellence is considered, it would be one of my top choices.”

University of California, Los Angeles (UCLA)

“Studying at UCLA was one of the greatest experiences of my life. The academics are rigorous and challenging without the pretentiousness of an ivy league or private school. I always had quality professors, many of which are making great advances in their respective fields. As the leading research institute in the country, there are many opportunities to get involved with those kinds of opportunities. The social life is also great. It’s the largest UC school in terms of population. There are many social/academic clubs and societies. Definitely a great school.”

Imperial College London

“There is definitely a big difference in the British way of teaching, with regard to the Swiss way, and it was a very good opportunity for me to compare both. You have everything you want at Imperial College and in London.”
