What Is a Master's in Computer Science?
The demand for professionals with computer science skills is growing both in and out of tech. According to a report from Burning Glass Technologies and Oracle Academy, demand is especially high in not only programming, IT and data analysis but also manufacturing, design and marketing. Roughly two-thirds of the highest-paying job listings in those fields ask for computer science skills—and, in some cases, a master's in computer science.
People assume the question 'What is a master's in computer science' is a simple one to answer, but this degree is so versatile that you can't accurately answer that question without asking and then answering a few more. The most important thing you need to know is that a computer science master's such as Case Western Reserve University's Online Master of Science in Computer Science (MSCS) can qualify you to step into more senior roles in a variety of industries—not just tech—while also boosting your earning potential. However, to stay focused after you're admitted into a computer science master's program, you need to understand what it is you're aiming for and the impact you can make with this degree.
What is computer science?
Broadly, computer science is the study of computational technology and the systems governing it. It may be more accurate, however, to treat computer science not as a single discipline but as a range of related disciplines that each have numerous subdisciplines. Technologies driven by computer science now power a range of industries, including transportation, healthcare, manufacturing, education and financial services. For instance, many doctors and medical professionals use artificial intelligence to support clinical decision-making. Farmers can leverage machine learning and networked Internet of Things (IoT) systems to improve crop health and yields. Computer vision is making it easier to keep physical locations secure and to identify streets where traffic accidents are more likely to occur.
Demand for computer science professionals such as software engineers, cybersecurity analysts, network engineers and computer architects is already high, but the Bureau of Labor Statistics (BLS) reports there's still room for growth. Demand for computer scientists—professionals who study the applications and limits of computational systems—is anticipated to increase by 15% in the coming decade. The number of jobs for database professionals likely will grow by 10%, and employers are expecting to create more than 300,000 new jobs in software development. There will be 500,000 new jobs for computer science, information technology and information systems professionals by 2029. Each of those is expected to lead to the creation of five additional jobs in professional and non-professional sectors outside of technology.
What distinguishes computer science from other areas of technology?
Scope is the answer because computer science is such a vast discipline. While there is no standard list of fields of study within computer science, a simple list of computer science specializations might include programming, computer architecture, artificial intelligence, database systems, networking, graphics and visualization, cybersecurity and algorithm design. Because computer science subfields are often closely related, many people mistakenly equate them with computer science as a whole.
The easiest way to understand how computer science differs from related disciplines is to look at each in turn. For instance, cybersecurity is a branch of computer science focused on securing computers, networked systems and data against accidental or malicious misuse. Information systems professionals use computational technology to collect, process, store and analyze data. Information technology (IT) takes systems created by computer scientists and configures them to meet specific user needs. Software engineers apply the protocols of computer science when they design and maintain software-based computer systems.
What exactly is a master's in computer science?
The MSCS is a graduate-level computer science degree for computer scientists, information technology professionals and other technology professionals who want to increase their knowledge of practical and theoretical computer science concepts. While graduate computer science degree programs often cover the same general body of knowledge, they can vary considerably from university to university and there's no typical MSCS curriculum. At some schools, MSCS candidates take core classes focused on advanced computer science fundamentals. At others, students select a computer science specialization and choose from among related elective computer science courses.
Program format also varies. There are immersive full-time, on-campus programs geared toward students fresh out of bachelor's degree programs as well as hybrid programs made up of a mix of in-person and online courses. Other MSCS programs attract working professionals with significant experience.
The online computer science master's offered by Case Western Reserve University’s Case School of Engineering is an example of an MSCS program for aspiring tech leaders who are skilled in multiple programming languages and software systems. Successful applicants are often already experienced software engineers, computer systems analysts and information systems specialists. Some are looking to pivot in technology careers while others want to advance in their current fields or transition into research.
How long does it take to earn a master's in computer science at CWRU?
The significant variation among computer science master's programs extends to program length. There are accelerated MSCS programs that take just one year to complete and part-time computer science master's programs that last three years or more. Case Western Reserve's 10-course, 30-credit online Master of Science in Computer Science program lasts five semesters when you take just two courses per term. You can graduate in under two years without taking time out of the workforce. While enrolled, you'll complete a blend of self-paced coursework and live virtual classes in whatever order you prefer, and your weekly commitment will be about six to nine hours.
How much does a master's in computer science usually cost?
Many prospective students ask this question, but the answer isn't particularly illuminating because tuition rates vary widely from institution to institution and most students receive some form of financial assistance. It's more accurate to assess the cost of a master's in computer science by looking at the return on investment, or ROI, of this degree. For example, Case Western Reserve's 30-credit online computer science master's costs $1,500 per credit hour, which adds up to $45,000 total tuition—a figure lower than the MSCS tuition at many comparably prestigious institutions. Meanwhile, an MSCS can increase a computer and information systems professional's lifetime earning potential by anywhere from $500,000 to $1 million—or even more—based on average salaries associated with computer science bachelor's degrees and computer science master's degrees.
Online computer science master's degrees aren't less expensive than on-campus programs on paper, but as a distance learner, your opportunity costs may be lower than those of your peers in on-campus programs. You can enroll in a distinguished computer science program without having to relocate, saving you thousands of dollars. You'll continue earning income and accruing professional experience while enrolled, which means your short-term earning potential won't be negatively affected by your decision to go to graduate school. And you won't have to pay transportation expenses, which add up quickly for most commuter students.
What skills do students develop in MSCS programs?
Computer science master's coursework differs from program to program, but highly ranked schools tend to cover concepts such as advanced programming paradigms, AI and intelligent systems, computational perception, algorithm analysis and design, networked systems, database systems, system security and privacy, data mining and software engineering. The programs that stand out as particularly excellent tend to teach both leading-edge technical skills and the kinds of transferable soft skills that many employers regard as especially valuable.
Case Western Reserve doesn't distinguish between its in-person and online programs at the graduate level. You will graduate from the online computer science master's program with leading-edge technical skills related to algorithms, computational theory, artificial intelligence, databases and data mining, as well as advanced soft skills related to communication, collaboration, intellectual flexibility, problem solving and leadership.

How much money do computer science master's holders make?
There are two ways to consider this question. You can look at averages across computer science-driven professions. Data collected by sites such as PayScale suggest the typical computer science bachelor's degree holder earns about $87,000 while the typical Master of Science in Computer Science holder earns about $104,000—or nearly twice the median household income in the U.S. That's a compelling figure but not one that tells the whole story.
To answer this question accurately, you need to look at mid- and senior-level salaries in different areas of computer science. Given the breadth of this discipline, it should come as no surprise that MSCS salaries vary considerably based on factors such as title and responsibilities. The typical information security analyst, software developer or mobile developer with a computer science master's degree will probably earn close to the above average. Artificial intelligence specialists, software engineering managers, principal technical program managers, senior solutions architects and especially chief technology officers can earn a lot more.
Just be aware that a computer science master's degree is not a one-way ticket to prosperity.
