IT is the area of managing technology and spans a wide variety of areas that include computer software,information systems,computer hardware,programming languages but are not limited to things such as processes, 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 IT domain. IT provides businesses with four sets of core services to help execute the business strategy: business process automation, providing information, connecting with customers, and productivity tools.
IT professionals perform a variety of functions 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, server management, database and software design, as well as management and administration of entire systems.
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[4] for degrees in Information Technology as a distinct field of study as compared[5] to Computer Science andInformation Systems today. SIGITE (Special Interest Group for IT Education)[6] is the ACM working group for defining these standards. The Worldwide IT services revenue totaled $763 billion in 2009.
