What Is Information Technology?

[Rokeya]

A 1958 article in Harvard Business Review referred to information technology as consisting of three basic parts: computational data processing, decision support, and business software. This time period marked the beginning of IT as an officially defined area of business; in fact, this article probably coined the term.


Over the ensuing decades, many corporations created so-called "IT departments" to manage the computer technologies related to their business. Whatever these departments worked on became the de facto definition of Information Technology, one that has evolved over time. Today, IT departments have responsibilities in areas like

computer tech support
business computer network and database administration
business software deployment
information security
Especially during the dot-com boom of the 1990s, Information Technology also became associated with aspects of computing beyond those owned by IT departments. This broader definition of IT includes areas like:

software development
computer systems architecture
project management.
