What is information technology or IT? Definition and examples

IT or information technology refers to the development, maintenance, and use of computer software, systems, and networks. It includes their use for the processing and distribution of data. Data means information, facts, statistics, etc., gathered together for reference, storage, or analysis.

The field of Information Technology is mostly focused on the business applications of computer-related knowledge. It does not focus much on the programming aspect, unlike CS.

IT students learn how to solve business problems by using technical resources efficiently. Regardless of which industry you are part of, you may be presented with applying your IT skills to its business processes.

An essential part of IT is information exchange. Considering the name of this field, it is quite clear that a large part of this field is heavily reliant on data.  Wherever there is transmission or exchange of data happening, you may have an opportunity to improve this process via efficient IT solutions.

Besides data management, you also have the option to solve networking or security problems. You can think of yourself as a troubleshooter. Whenever a member of an organization faces any technological challenge, who do they call for help? That’s right – an IT professional..
