Information Systems vs. Information Technology (IS vs. IT)

Information systems vs. information technology

Information systems (IS) and information technology (IT) are closely related disciplines that are often mistaken for one another. IS focuses more closely on information-handling processes, while IT tends to center on the technologies that support those processes. Despite some overlap in concepts and practices, each field of study is unique. If you’re considering a career in either one, learning about their differences can help guide your decision-making process.

Upon completion, you’ll have earned a career certificate for your resume and had the opportunity to gain the skills you need to succeed in an entry-level IT role.

What are information systems (IS)? 

An information system (IS) or computer information system (CIS) is a set of interconnected people, processes, software, hardware, and networks. Its primary goal is to manage data as it flows through the following five stages:

1. Input

2. Processing

3. Storage

4. Output

5. Feedback 

What is information technology (IT)?

Information technology refers to the use of computer systems to manage, process, protect, and exchange information. The IT industry is a vast field of expertise that includes a variety of subfields and specializations. Overall, the goal of IT is to use technology systems to solve problems and handle information.

IS vs. IT: Difference between information systems and information technology industries 

One of the key differences between IS and IT is the involvement of business concepts. Information systems professionals are well-versed in business concepts and applications. Information technology professionals tend to focus more on the technology that supports those business initiatives. Nearly every industry requires both IT and IS professionals. According to the US Bureau of Labor Statistics (BLS), occupations in the computer and technology industry should have 317,700 openings each year between 2024 and 2034 [1]. 

Subcategories of IT include:

• Health information technology

• Cybersecurity

• Business information technology (BIT) 

Like IT, information systems is a vast field. Areas of expertise that fall under the umbrella of IS include:

• Hospital information systems (HIS)

• Financial technology (fintech)

• Manufacturing

Information technology vs. information science

Information science is the study of how information is generated, organized, stored, shared, managed, and used. IT focuses on the technical implementation and management of information systems technology.

Computer information systems vs. computer information technology degrees

Computer information systems (CIS) degrees and information technology degrees cover many of the same areas of expertise. Here are a few subjects both degrees have in common:

• Programming

• Cybersecurity

• Computer networking

• AI and machine learning

• Computer organization and architecture

• Database design and administration

Some courses CIS students may take that IT students may not include:

• Business systems analysis

• Business law

• Systems analysis and design

Coursework that may be unique to IT students includes:

• Program design

• Communication for engineers

• Application maintenance and debugging

CIS career path

Due to the similarities between these two fields, IT and CIS career paths can overlap. Check out an example career path for someone who wants to work in CIS and then compare it to an example career path in IT. 

The salary information below represents the median annual total pay according to Glassdoor’s September 2025 data. The figures include base salary and additional pay, which may represent profit-sharing, commissions, bonuses, or other compensation.

Many begin their career in an entry-level IT or CIS role, such as:

You will often design databases and define security measures to protect that data. Information systems specialists earn a median pay of $108,000 annually. 

Senior-level information systems positions may require a security clearance and several years of experience.

• Senior systems engineer: Senior-level systems engineering roles may require more leadership and management responsibilities. Senior systems engineers ensure system architecture and processes are compliant with industry standards and manage projects by facilitating cross-department collaboration. The median yearly pay for senior systems engineers in the US is $179,000.

• Operating system engineers: OS engineers design and test operating systems, software, and other systems management tools. You will engage in technical planning, management, and the integration of new technologies. In the US, operating system engineers earn a median pay of $205,000 a year. 

IT career path

Recent graduates and those transitioning into IT from another career are likely to begin in an entry-level IT job, such as:

• IT technician: IT technicians are similar to help desk technicians. Sometimes, the job titles are used interchangeably. However, help desk technicians tend to focus on assisting customers or users outside of their organization. Your primary goal as an IT technician is to help members of your organization with software and hardware troubleshooting. IT technicians in the US earn a median salary of $61,000 per year. 

• Web developer: Web developers build websites that organizations and businesses use to operate and interact with their customers. Web developers earn a median salary of $99,000 in the US.
