Inquisitive and determined are the attributes marked by students journeying to earn a data science or computer science master’s. These traits come in hand as, despite their vast knowledge in the sciences, working professionals are often challenged to keep up with the constantly changing nature of their fields.
To illustrate the branching out of Computer Science into Data Science, consider the evolution of the bicycle into the Peloton bike. The strong mechanics of the basic bicycle created the foundation for its transformation into the a-tech fitness phenomenon. Similarly, computer science is the essential foundation of data science, and as a collective unit, these sciences have furthered technology to incredible heights.
Understanding the differences between a master’s in data science versus computer science can be key when considering your next career move, as each program offers a different path and expertise.
Master’s in Computer Science Overview
The study of computer science at the master level is all-encompassing. The program provides advanced training in computational design, security, programming theory, architecture, applications, software development, and hardware. This comprehensive approach to computing offers insight into networks, operations, design parameters, and databases—with specialized topics. A computer science master’s degree provides graduates with a wide range of career paths in the information technology arena.

Master’s in Data Science vs Masters in Computer Science: Key Differences
When examining the core differences between a data science versus computer science master’s, it is helpful to study the general focal areas side by side, per the table below:
| Computer Science | Data Science |
| Software Engineering | Mathematical Data Science |
| Cybersecurity | Artificial Intelligence |
| Computational Theory | Probability Theory |
| Programming Languages | Python Programming |
| Database Systems | Big Data |
| Algorithms | Stats & Statistical Analysis Methods |
| Operating Systems | Reinforcement Learning |
The vision for both science fields is also unique and may embolden students to confidently choose between one or the other.
Some are guided by the words of Marc Andreessen, computer scientist and inventor of Netscape, “The spread of computers and the Internet will put jobs in two categories. People who tell computers what to do, and people who are told by computers what to do.” These technologists are motivated to operate entirely through the computer.
Others find inspiration in the words of Peter Sondergaard, data scientist and Senior Vice President of Garner Research, “Information is the oil of the 21st century, and analytics is the combustion engine.” Finding key, decision-influencing gems within millions of rows of customer data can be incredibly gratifying.
The decision between a master’s degree in data science versus computer science may be determined based on which quote and idea is most appealing to you.
Prerequisites
Before graduate program advancement, you should have completed a bachelors’ degree. There are college-level requirements of calculus, advanced math, and Java/Python coursework for both degrees. For computer science, additional data structures and computer organization experience are needed.
While the prerequisites are the same, the skill “must-haves” do vary. A computer science program appeals to students who have an affinity to the science disciplines, specifically subjects that call for applied analytics and logic.
In contrast, data science incorporates algorithms, database concepts, programming languages, and statistics. Whether contemplating a master’s in data science or computer science, an aptitude for math is imperative.
Curriculum
In both curriculums, students are often required to complete a total of 10 courses. Depending on the school, the general syllabus may be organized as follows:
| # Required | # Elective | |
| Computer Science | 3 |
|
| Data Science | 7 |
|
The computer science curriculum is designed to a) foster a broad perspective of the general field and then b) take a deep dive into a concentration track. Areas of concentration may include but are not limited to independent research, theory, applications, systems, software, and reasoning.
The data science prospectus is typically comprised of foundation, required, and elective courses. Additionally, class titles range from cloud computing and network security to modern cryptography and computational genomics.
Skills
It is useful, when analyzing a computer science versus data science master’s, to hone in on the skill requirements. When deciding, consider the personal question, should I delve into what comes naturally or build on skills that I may not currently excel in?
Again, there is overlap, so review the respective attributes for each:
| Computer Science | Data Science | |
| Technical Mastery/Toolbox |
