Define Information Technology:
IT is a term used to describe several aspects: the task of gathering data and
processing it into information, the
ability to disseminate information using technology, the technology itself
that permits these tasks, and the
collection of people who are in charge of maintaining the IT infrastructure
(the computers, the networks, and
the operating systems). Generically, we will consider IT to be the technology
used in creating, maintaining, and
making information accessible. In other words, IT combines people with
computing resources, software, data,
and computer networks.
Information technology
describes the technology infrastructure that may support information
systems,
although Information Technology could also support many other types of
systems (e.g., telecommunications
systems). Information Technology includes hardware, software, networks,
and databases that work together to
allow an organization to manage data and information.
