Information Technology: What is it? And how is it changing?

Search Data Centredescribes information technology (IT) as the use of any computers, storage, networking and other physical devices, infrastructure and processes to create, process, store, secure and exchange all forms of electronic data.

The term information technology was coined by the Harvard Business Review, in order to make a distinction between purpose-built machines designed to perform a limited scope of functions and general-purpose computing machines that could be programmed for various tasks.

IT Hardware and Software

IT includes various layers of equipment (hardware), such as desktop computers, laptop computers, smartphones, external hard drives and keyboards. Operating systems, applications and tools (software) are used to perform essential functions.

The information technology profession is extremely diverse: IT workers can specialize in fields like software development, application management, hardware and network architecture. Many businesses seek IT professionals with mixed or overlapping skill sets.
