While both are rapidly growing fields with diverse career opportunities, computer science and information technology (IT) differ in that computer science refers to the theory and processes involved in designing hardware, software and applications. IT focuses on utilizing technology to address issues and those technologies to guarantee the smooth operation of the computers, networks, systems and databases they oversee.

Computer science is concerned with the study of computers and computing, focusing on algorithms, programs and programming and computational systems. Computer scientists build a systematic body of knowledge, theories and models that explain the properties of computational systems and show how this body of knowledge can solve real-world computational problems. Career examples include web developers, software engineers and data analysts.

Information technology involves using computers, devices, technological infrastructure and computer science-driven software and processes to find technical solutions to problems. Career examples include database administrators and cybersecurity specialists.

This page will explain in more detail how these two fields differ and offer information about the educational paths, skills for success and career outcomes that define each.

What is Information Technology?

Information technology specialists apply their knowledge of computers, software and systems in a variety of ways to help organizations adopt new technologies, secure their data, develop and maintain technological systems, analyze and make sense of data and more as new technologies emerge.

Emerging technologies in IT include:

  • Artificial intelligence (AI) and machine learning (ML)
  • Big Data
  • Blockchain
  • Cloud computing
  • Cybersecurity
  • Data science
  • DevOps
  • Internet of Things (IoT)

Is Information Technology A Part of Computer Science?

Computer Science includes Information Technology as a subset. Computer Science is a wide-ranging discipline that covers the study of computers and computational systems, encompassing their design, creation and utilization. In contrast, IT concentrates on the practical implementation of computer systems and technology to address real-world issues. IT experts utilize their computer systems and software expertise to manage and maintain computer networks, develop software applications and provide technical assistance to users. Although IT is a specialized field within Computer Science, both fields are closely linked and share many of the same fundamental principles and concepts.

CS vs IT: Career Paths

Computer science graduates usually pursue software development, programming and computer engineering careers, while IT graduates tend to work in network administration, technical support and database management. Their responsibilities include designing and developing software applications, operating systems and computer hardware, as well as managing and maintaining computer systems, troubleshooting technical issues and ensuring data and network security. Both fields offer numerous career prospects and high demand for skilled professionals.

Computer Science vs IT: Roles and Salaries

Although Computer Science and Information Technology both involve computers and technology, they have different roles and pay scales. While computer scientists typically earn more than IT professionals due to their specialized skills and expertise, both fields offer lucrative career opportunities for those with the right qualifications and abilities. Roles and salaries vary greatly based on educational and work experience, required or recommended specializations and certifications, market demand and other factors.

Computer Science Job Titles Approx. Salaries
Artificial Intelligence Engineer $131,490
Software Engineer $120,730
Robotics Engineer $101,758
Data Scientist $100,910
Computer Programmer $93,000

Advanced roles in either of these two specialties typically require more education and training and come with a higher earning potential. As AI and machine learning, blockchain and cloud computing technologies are adopted for more widespread use, for example, both IT and computer science specialists with deeper knowledge and skill sets in those areas would likely be in greater demand for these careers and command higher salaries.

Is Information Technology A Good Career?

Information technology is an excellent career choice for those who are interested in technology and enjoy problem-solving. The field is constantly evolving and offers a wide range of job opportunities, from network administration to cybersecurity to cloud computing. Additionally, the demand for IT professionals is high, with many companies seeking skilled workers to help them stay competitive in the digital age. Salaries are competitive and there are often opportunities for advancement.

It is important to keep up with the latest technologies and trends in the field to remain competitive and successful in this career path. Pursuing an Online Master of Computer Science degree from Rice University will give you a competitive advantage in both finding a job in this in-demand field and landing a role with greater leadership and decision-making opportunities and, likely, a higher salary.

Which Pays More? Computer Science or Information Technology

Determining which field pays more, computer science or information technology, is complex as several factors such as location, experience and job role can affect salaries. Generally, computer science jobs tend to offer higher pay than information technology jobs, particularly in software development, artificial intelligence and data science. However, information technology jobs can also provide competitive salaries, especially in cybersecurity and network administration. Ultimately, choosing between computer science and information technology should also be based on personal interests, skills and career aspirations, in addition to earning potential.

The median salary for computer science and IT positions was $97,430 as of May 2021. Salaries range widely for both IT and computer science jobs, with some average base salaries climbing above $100,000. According to the Bureau of Labor Statistics, computer and information research scientists made an average of $131,490 in 2021. Information security analysts made an average of $102,600 in 2021.

A master of computer science degree can help you strengthen your command of computer science overall and provide you with the practical skills to excel in a variety of information technology fields — increasing your earning potential in either area.
