Few industries offer students a more promising outlook than those in the computer and information technology field. The Bureau of Labor Statistics projects 13% job growth between 2020 and 2030 for computer and IT professionals — nearly three times faster than the national average. Moreover, the field's median annual salary of $88,240 is more than double the median annual salary for all occupations in the U.S.

Computer science (CS) and computer information systems (CIS) represent two popular educational pathways into this industry, but many people struggle to differentiate between these two disciplines. With the help of Chirag Shah, an associate professor at the University of Washington's Information School, we break down what separates these two fields.

What Is Computer Information Systems?

CIS training focuses on the business and solutions-based applications of various computer systems. "You can think of CIS as a very specialized application domain of CS," Shah says. Students often take courses in networks, systems, and database administration, along with some business analysis and support training classes.

Most programs teach learners how technology can improve organizational processes and decisions. Since these professionals interact with different business levels and personnel, they usually need strong business, communication, and organizational skills, as well as leadership, decision-making, and analytical capabilities.

The practical nature of this program means that internships often play a large role. Students should consider this potential work experience when evaluating programs.

What Is Computer Science?

CS emphasizes the theoretical side of computer hardware and software, providing a comprehensive study of "computational systems from their conceptualization to implementation," according to Shah. Learners study various programming languages and algorithm analysis techniques, preparing to design and develop effective, reliable, and secure software. Many programs begin with systems fundamentals and then move on to programming, data structures, testing, and user experience.

In general, computer science programs teach students about computation and information analysis methods and technologies. Professionals rely on their ingenuity and logic, and they need strong communication, mathematics, and critical thinking skills.

The broad nature of computer science allows learners to choose from many specializations and career paths, including those related to mobile computing, artificial intelligence, data analytics, and cloud computing.

Computer Information Systems vs. Computer Science

When deciding between computer information systems and computer science, students should consider their personal and professional interests and choose a program that best meets them. Shah highlights the programs' key similarities and differences.

CS professionals create the programs and applications that CIS managers implement and supervise for their organizations.

"In CS, one can learn about designing a new algorithm," he says. "Whereas in CIS, one can learn about how a system that uses such an algorithm can fulfill specific purposes in a real-life situation."

CIS professionals work with a variety of technologies, looking for programs, devices, and applications that can improve business operations. They use their programming and design expertise to integrate and maintain technologies, while employing project and administration management skills as they oversee each component of a project. They primarily focus on how technologies operate within a business environment, choosing the most effective option based on their organization's needs.

By contrast, the CS discipline deals with computational system design and development. Workers in this field improve the applicability, power, and effectiveness of various devices. Professionals create the programs and applications that computer information systems managers implement and supervise for their organizations.

Which Path Is Right for You?

To choose the right discipline, students must think about their interests and career goals. While graduates from both disciplines may pursue similar career paths, the concentrated training in each program prepares learners for specific opportunities. Students may also pursue coding bootcamps or industry certification to support or diversify their professional pursuits.

CS careers tend to be more technical, whereas CIS careers are more practical.

Computer information systems professionals usually work as part of a team, implementing and managing computer-based business solutions. In addition to possessing hardware and software knowledge, they must have a solid business foundation and interpersonal skills to provide the best support.

Shah suggests that the field best suits "those who want to deploy and support computational systems in business settings without having to learn about the fundamentals of what drives those systems."

Computer science requires great attention to detail and patience. Careers in this field tend to be more technical, whereas computer information systems careers are more practical. According to Shah, computer science best suits "those who have a strong passion for technology, are interested in going deeper in conceptual understanding, and are looking for more choices going forward."

Frequently Asked Questions About Computer Science

How are the subjects of computer information systems and computer science similar?

Computer science (CS) is a discipline that includes studies of computational systems from their conceptualization to implementation. Typical topics include algorithms, computer architecture, artificial intelligence, database, and networking.

Computer information systems (CIS), on the other hand, is a very specific field that focuses on networked computers being deployed in various business situations. You can think of CIS as a very specialized application domain of CS. Both fields cover subjects like databases, computer networking, and security.

What are the main differences between these two subject areas?

CIS is application-driven. While CS provides a comprehensive education ranging from very theoretical topics to those that are application-oriented, CIS is very much situated in applications in different businesses.

Studies in CIS tend to be more hands on, large-scale, and in situ (think about case studies). In CS, one can learn about designing a new algorithm, whereas in CIS one can learn about how a system that uses such an algorithm can fulfill specific purposes in a real-life situation. Some examples of CIS include office automation, payment systems, and health technology systems.

What skills are taught in computer information systems classes or courses?

CIS students learn about technology (databases, security, programming, networking) as well as business (management principles, finance and accounting, business laws, economics). Invariably, most CIS programs (bachelor's or master's) also include a capstone project or internship to gain real-life experiences.

What skills are taught in computer science classes or courses?

CS starts with computational thinking, which means being able to understand, represent, and solve problems using a systematic process that can be scaled and mapped reliably. CS courses include algorithms, data structures, programming, computer architecture, networking, databases, and artificial intelligence.

What kind of individuals are best suited to study computer information systems? Why?

CIS is a good choice for those who want to deploy and support computational systems in business settings without having to learn about the fundamentals of what drives those systems. CIS provides a clear and strong career path for various kinds of administrators (system admin, database admin, network admin).

CIS is an attractive option for those with a technical inkling and an eye on management roles, as the field allows them to focus on and practice specific skill sets and move quickly on their career path.
