DThe use of principles of physical and social sciences for processing information
Correct answer: (C) The use of hardware and software for the storage, retrieval, processing and distribution of information of many kinds
Explanation
Information technology is best defined as using hardware and software for the storage, retrieval, processing and distribution of many kinds of information.
Limiting it to only processing information leaves out storage, retrieval and distribution.
Limiting it to only distribution of useful information ignores the processing and storage roles.
Framing it through physical and social science principles describes a discipline, not the technology itself.
The broad definition captures the full information life cycle that IT supports.
This is why IT covers everything from databases to networks and output devices.
