Information technology (IT) majors study a broad range of technological topics, including website development and management, networking, security fundamentals, managerial economics, computer programming, digital media publishing, application development, information systems, and databases. IT is an intense program that focuses on the design of technological information systems, including computing systems, which is why it?s imperative that students have strong math, computer, quantitative, and problem-solving skills. Certification is not necessarily required for IT positions but is often preferred since it illustrates ongoing knowledge of the industry.
The IT industry is the largest of any computer-related industry. IT workers maintain networks, create new software, and ensure information security. Custom computer programming services and computer systems design services are the two sub-industries that account for almost 90 percent of all IT services employment. IT workers in those areas write, test, and modify software; provide support to clients after new software has been introduced; and plan and design computer systems. However, IT graduates are qualified to work in other areas including data management, software installation, and disaster recovery services. Employment and output in the computer systems design and related services industry is expected to continuously grow at a rapid pace as firms and individual consumers continue to increase their use of information technology services.
