Different sources provide different definitions. A few of these definitions and their sources are included, below...
The International Foundation for Information Technology (IF4IT) provides three definitions for Information Technology:
1. The technology used for the study, understanding, planning, design, construction, testing, distribution, support and operations of software, computers and computer related systems that exist for the purpose of Data, Information and Knowledge processing.
2. The industry that has evolved to include the study, science, and solution sets for all aspects of Data, Information and Knowledge management and/or processing.
3. The Organization in an enterprise or business that is held responsible and accountable for the technology used for planning, design, construction, testing, distribution, support and operations of software, computers and computer related systems that exist for the purpose of Data, Information and Knowledge management and/or processing.
The Interoperability Clearinghoure (ICH) defines Information Technology as follows:
Includes all matters concerned with the furtherance of computer science and technology and with the design, development, installation, and implementation of information systems and applications [San Diego State University]. An information technology architecture is an integrated framework for acquiring and evolving IT to achieve strategic goals. It has both logical and technical components. Logical components include mission, functional and information requirements, system configurations, and information flows. Technical components include IT standards and rules that will be used to implement the logical architecture.
TechAmerica, formerly the Information Technology Association of America (ITAA), defines Information Technology as
"the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information.
