Information technology professionals provide hardware, software, and one-on-one device support. Although most people’s interactions with IT involve computer issues, the work extends far beyond that. IT departments usually have three areas of responsibility –- operations, infrastructure and maintenance, and management. IT operations generally encompass engineering, database administration, or development. 

IT roles include:

• Operations engineers: Operations engineers install, run, and manage networks, servers, and external services such as cloud computing. 
• Database administrators: These professionals create and maintain systems that store information.
• Development operators: DevOps engineers combine software engineering with coding skills to build software, improve it, and perform software deployments.

Does IT include cybersecurity?

Some people within and outside of technology-related careers consider cybersecurity an IT-related job. As with other professions, job titles and responsibilities sometimes overlap. As a result, IT and cybersecurity workers may collaborate or handle some of the same responsibilities. 

But when analyzing essential job skills and responsibilities, IT and cybersecurity professionals take different approaches to safeguard digital information. Cybersecurity tends to focus more on protecting the data itself than the infrastructure supporting it. As with cybersecurity, the number of people responsible for IT depends on a company’s resources. One person may handle multiple responsibilities –– or even everything IT-related.

Information technology jobs

More than 12 million Americans worked in the IT sector in 2019. The net employment of people in technology-related jobs grew by 307,000 workers, up 2.6% from 2018.
