IT spans a wide variety of areas that include but are not limited to things such as processes, computer software, computer hardware,
programming languages, and data constructs. In short, anything that renders data, information or perceived knowledge in any visual format whatsoever, via any multimedia distribution mechanism, is considered part of the domain space known as Information Technology (IT).
IT professionals perform a variety of functions (IT Disciplines/Competencies) that range from installing
applications to designing complex
computer networks and information
databases. A few of the duties that IT professionals perform may include
data management, networking, engineering
computer hardware, database and software design, as well as management and administration of entire systems. Information technology is starting to spread farther than the conventional
personal computer and network technology, and more into integrations of other technologies such as the use of cell phones, televisions, automobiles, and more, which is increasing the demand for such jobs.
In the recent past, the
Accreditation Board for Engineering and Technology and the
Association for Computing Machinery have collaborated to form accreditation and curriculum standards
[3] for degrees in Information Technology as a distinct field of study as compared
[4] to
Computer Science and
Information Systems today. SIGITE
[5] is the ACM working group for defining these standards. The Worldwide IT services revenue totaled $763 billion in 2009.
