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.
