Get to Know Computer Science (And Majors Similar to Computer Science!)

It’s okay to admit it: It’s not always obvious what you’ll study in a certain major, especially when it shares similarities with other majors. What’s the difference between data science and information systems? What’s a science compared to a system, anyway?

In this blog series, we’re going to delve into a few commonly confused areas of study, so you’ll have all the information you need to choose a major that best fits your interests. In this article, we’re looking at the differences between computer science and majors similar to computer science—namely, computer science, computer engineering, data science, information science, and information systems. Let’s dig in.


At a Glance …

Before we go into detail on each subject, here’s a taste of what you can expect from each major:


Computer Science

Who’s responsible for designing software, improving AI, and enhancing computer performance? You guessed it: computer scientists. If you study computer science, you can expect to learn all of that and more as you gain hands-on experience with building and designing computer systems. You’ll be on the cutting edge of problem-solving technology by using computers and algorithms to create new solutions in all kinds of fields. It’s also worth noting that the admit rate to the computer science major at UIUC is roughly 7%. That’s not to say you shouldn’t apply—just know it’s a highly competitive program!

What Careers Can You Expect From a Computer Science Degree?

Computer science degrees today have the potential to lead to some of the highest-paying careers available, including:

  • Software Developer

Data Science

Data scientists are expected to be proficient in technical computer skills, but their primary focus is on managing and interpreting datasets. Understanding datasets—whether that data is about people’s favorite ice cream flavors or the intricacies of machine learning—is so important because it makes it possible to analyze and interpret that data to make informed decisions about real-world variables. You could find yourself interpreting data for your own projects, a small startup, or a Fortune 500 company. 

What Careers Can You Expect From a Data Science Degree?

Data science is an increasingly popular degree, probably because it can lead to all of the following fields:

  • Data Scientist
  • Data Analyst 
  • Machine-Learning Engineer
  • Machine-Learning Scientist
  • Statistician

Information Science

Information science has its technical side—you’ll learn programming as well as how to design information systems, services, and more—but its primary focus is (surprise!) information. An information science degree will teach you to learn how to organize, manage, evaluate, and interpret information to make it usable in the real world. You’ll be streamlining communications between people (and between people and computers) so everyone has more reliable and consistent access to the information they need.

What Careers Can You Expect From an Information Science Degree?

The sky’s the limit with an information science degree, but some of your possible careers are:

  • Data Analyst 
  • Health Informatics Manager
  • Systems Analyst
  • Political Intelligence Consultant
  • Web Content Manager

Information Systems

Information systems is a business degree that relies heavily on tech experience and what can be accomplished when the two meet. Choosing to study information systems means delving into the world of how businesses use technology. You’ll be expected to integrate computer information systems with administrative know-how in order to make decisions that are backed by data and technology that can also work for your company’s business model. With an information systems degree to support you, you can become a business leader in a digital era. 

What Careers Can You Expect From an Information Systems Degree?

Ready to put your business acumen and tech experience to use? You could end up working in any of the following areas:

  • Consultancy 
  • Database Support
  • Network Administration 
  • Systems Analytics 
  • Technical Sales and Support
