If you’re passionate about computers and technology, you may be considering a career in either computer science or computer information systems. While both fields involve the study of computers and technology, they each have a unique focus and can lead to different career paths.

This guide will help pinpoint the key differences between computer science and computer information systems and help you make an informed decision on which degree is right for you.

Information technology, computer science, and computer information systems are all critical fields within the realm of technology, but each has its own distinct focus.

While both CS and CIS are firmly rooted in technology, they differ in their focus and coursework.

CS concentrates more on the theoretical and mathematical aspects of computing, including the development of new software systems, algorithms, and advanced software. It has a strong focus on calculus, discrete mathematics, and data structures.

You’ll study a broad range of areas in a computer science major, including machine learning, natural language processing, computing systems, networking, operating systems, AI, and human factors.

CIS explores how to use technology to solve business problems, manage data securely and efficiently, and support and maintain existing systems.

A CIS major covers application development, architecture, networking and security, business intelligence, and consulting. Coursework may include systems analysis and management, programming, cybersecurity, project management, economics, and supply chain management.

Students gain hands-on experience through projects, cases, and business simulations, which prepares them with strong technical, analytical, and problem-solving skills.

When choosing between CS and CIS, carefully consider your interests, career goals, and the curriculum of each program.

If you’re interested in the theoretical underpinnings of computers, enjoy tackling complex problems, and aspire to innovate technology, CS may be the right path for you. This field is about finding new ways for computers to improve life and requires a strong foundation in programming, algorithms, and computational theory.

On the other hand, if you’re interested in how technology can streamline business processes and decision-making, then CIS could be the way to go. CIS focuses on applying technology solutions to real-world business challenges. It requires an understanding of business operations, strategic planning, and technology implementation.

Your long-term career goals play a significant role in choosing between a CS and CIS degree.

If you are interested in the scientific and mathematical foundations of technology and would like to pursue a graduate degree, a CS degree may be more appropriate since it focuses on theory, mathematics, and creating new systems.

If you want a career working as a technology consultant or in managerial roles, a CIS degree might be a better fit. CIS emphasizes practical applications of technology in business, such as managing software systems and information security.

The career opportunities available to you can vary depending on whether you choose a degree in CS or CIS. There is potential for career growth in both CS and CIS, with the number of computer and information technology positions projected to grow faster than the average for all occupations, according to the Bureau of Labor Statistics (BLS).

The salary range for professionals with a CS degree varies based on factors such as experience, education level, location, and job role. The median annual salary of computer scientists was $145,080 as of May 2023, with a range of $81,450 for the lowest 10% of earners and more than $233,110 for the highest 10% of earners.

Professionals with a CIS degree can expect to earn similar salaries. For instance, as of May 2023, IT security analysts earned a median annual salary of $120,360, systems administrators earned $95,360, and information systems managers earned $169,510.

Deciding whether a master’s in CS or CIS is worth it depends on your career goals. A master’s degree in either field can lead to higher average salaries, expanded job opportunities, and the potential for steady job growth.

The return on investment also depends on the cost of the program, your current career status, and how much time you can invest in your education. Online master’s programs offer flexibility and may be more affordable, making them accessible for working professionals.
