Computer Science vs. Information Technology: What’s the Difference?

Industry Advice Computing and IT

The technology industry in today’s society is booming. As of 2019, only 10 percent of people in America report not using computers and the internet, and those numbers are even smaller in the business world, where companies have developed a majority of their processes and systems around the various technologies within their industry.

This reliance on technology has led to a substantial increase in the demand for workers who can develop, implement, and maintain such systems. Computing jobs alone have been ranked as the number one source of new wages in the United States, boasting over 500,000 current job openings across the nation.

This promising career outlook has led many students hoping to continue their education with a graduate degree to explore careers in the technology field, yet with so many different options to pursue, it can be difficult to understand which roles correspond with which skill sets, responsibilities, and job titles within the industry.

Read on to uncover the core differences between two common areas of study in the technology field: computer science and information technology (IT).

What is Computer Science?

At its core, a study of computer science includes learning about the “mathematics and the algorithms that are needed to build and solve problems using computers,” says Ian Gorton, director of the computer science master’s programs at Northeastern University—Seattle. It involves an understanding of both the theories and abstract concepts that computing is based in, as well as the use of practical programming skills to build code and develop complex systems.

Students who choose to study computer science at the graduate level will learn about the various tools and practices that go into this technology development process, alongside how to deploy their own systems and consistently update and improve those systems over time.

Within this broader framework of understanding, students are also often able to choose a specialty in the field. As part of Northeastern’s Master of Science in Computer Science program, for example, students can pick from specialties such as Artificial Intelligence, Information Security, Networks, Computer-Human Interface, Game Design, and more.

What is Information Technology?

Unlike computer science—which focuses on the skills needed to build complex systems from the ground up—information technology specialists “configure those systems to solve a business’ problems,” Gorton says.

 Individuals in IT roles must take ownership of these systems within an organization and work to ensure that they are not only integrated properly upon introduction, but that they are running correctly and continue to function appropriately over time.

Some of the most common systems IT specialists work with include:

  • Databases
  • Servers
  • Networks
  • Software
  • Hardware
  • Industry-specific systems or tools

Although hands-on work with technology is a significant aspect of an IT specialists’ work, it’s also important that these individuals have effective business skills in order to thrive in this field. Additional responsibilities may include technical support duties, analyzing processes, configuring networks, and training employees on best practices for utilizing certain complex systems.

Computer Science vs. Information Technology: Responsibilities

Gorton identifies that one of the main differences between these two disciplines is that computer science “is more technically-facing, and [IT] is more business-facing.” This means that, in general, the scope of work for individuals working in IT is focused on fulfilling a specific organization’s needs with technical suggestions and support. In contrast, the scope of work for a computer scientist remains focused on the unique product or programs they are developing, without having to consider the application of those programs after they’ve been deployed.

Those who work in computer science and information technology also face a variety of unique responsibilities depending on the industry. Explore the general responsibilities for each discipline below.

Computer Science Responsibilities

  • Updating existing hardware and software for efficiency and ease.
  • Writing code for new computer programs, websites, applications for mobile devices, and other industry-specific systems such as databases, cloud-based storage, artificial intelligence products, and more.
  • Deploying systems, including the installation, configuration, testing, and adaptation of those within a new environment. This is work that is done on a continual basis, as programs update, change, and improve.
  • Presenting developed programs to businesses as part of the sales process of a new product. As computer scientists have the most technical understanding of how a program they’ve developed works, these professionals will likely be in charge of demonstrating its functionality to businesses.
  • Managing a team when the designing of a program includes many stages, components, or stakeholders. This may require them to step into a more project management or facilitator role, which includes helping guide the group through the development process.
  • Publishing industry articles on complex mathematics and computer science theories.

Information Technology Responsibilities 

  • Working closely with the business they support to understand their goals and implement the systems needed to achieve those goals.
  • Integrating various systems, ensuring they function cohesively within an organization. This may include databases, networks, clouds, storage drives, and more.
  • Maintaining the function of those systems over time, keeping up with updates, improvements, and new products as needed.
  • Programming, but to a much lesser extent than that of a computer scientist. Gorton explains that an information technology graduate can “build basic [programs], just not super complex ones.”
  • Working with vendors on cost and efficiency estimates on new products and the processes through which those products can be integrated into existing systems to add new features or value.
  • Keeping up with relevant rules and laws regarding products, including licensing and other mandates.
