The study and practice of using computers and other communication systems to transmit, organize, access, and manipulate data is known as information technology. Information technology is a broad term used in many industries, including business, engineering, and medicine. Because the study of information technology is so broad, most college information technology programs specialize in areas such as application development (also known as software development), systems analysis (the study of analyzing and determining the viability and configurability of information systems), and electronic health records (the study of data and information management systems used in the healthcare industry).

Whatever course of study a student chooses, the central concept of all information technology studies is learning how to organize and store data using various telecommunication systems.

The application of technology to solve organizational and business problems is known as information technology (IT). To deal with and manipulate information/data, this field of engineering employs computers, networks, storage, and other technical infrastructure, both hardware and software. IT professionals are adept with the most recent emerging technologies, arriving at the most optimal (requiring the least amount of time and effort) solutions to any technical issues that may arise, large or small. An Information Technology department has many responsibilities; professionals follow a combination of policies and processes to ensure IT systems run effectively and are designed to align with the organizational strategy; they focus on providing technical support, preservation, remote management, and security testing and evaluation.

The course covers IT disciplines such as systems and services, networking and security, scripting and programming, data management, and information technology business. The course also covers technologies in these fields.
