The terms “information technology” and “IT” are widely used in business and the field of computing. People use the terms generically when referring to various kinds of computer-related work, which sometimes confuses their meaning.

What Is Information Technology?

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.

Today, IT departments have responsibilities in areas like computer tech support, business computer network and database administration, business software deployment, and information security.

This broader definition of IT includes areas like software development, computer systems architecture, and project management.Information Technology Jobs and Careers
