Information Technology (IT), or in English known as Information technology (IT) is a generic term for any technology that helps humans create, modify, store, communicate and / or disseminate information. IT brings together high-speed computing and communications for data, voice and video. Examples of Information Technology are not just personal computers, but also telephones, TVs, electronic appliances, and modern handheld devices (such as mobile phones). [1] In a business context, the Information Technology Association of America explains
Processing, storage and dissemination of vocal, pictorial, textual and numerical information by microelectronics based on a combination of computing and telecommunications. [2] The term in the modern sense first appeared in a 1958 article published in the Harvard Business Review, in which the authors Leavitt and Whisler commented that "new technology has not had a single name established.We will call it information technology (IT)." Some of the modern and emerging fields of information technology are the next generation of web technologies, bioinformatics, '' Cloud Computing '', global information systems, large-scale knowledge base and others. At the beginning of history, humans exchange information through language. So the language is technology, the language allows one to understand the information conveyed by others but it does not last long because Once the speech is finished, then the information in the hands of the recipient will be forgotten and can not be stored for long. In addition the voice range is also limited.
IT is a field of technology management and covers a wide range of areas including but not limited to things like processes, computer software, information systems, computer hardware, programming languages, and construction data. In short, what makes data, information or perceived knowledge in any visual format, through any multimedia distribution mechanism, is considered part of IT. IT provides businesses with four sets of core services to help run the business strategy: business process automation, providing information, connecting with customers, and productivity tools.
IT performs various functions (IT Discipline / Competence) from installing Applications for designing computer networks and Database information. Some of the tasks IT does may include data management, networking, computer hardware engineering, database and software design, as well as overall system management and administration. Information technology is starting to spread further than conventional personal computers and network technology, and more into the integration of other technologies such as the use of mobile phones, televisions, cars, and more, which increases the demand for jobs.
In the past, the (Accreditation Council for Engineering and Technology) and the Association for computing machines have collaborated to establish curriculum accreditation and standards [4] for degrees programs in Information Technology as a field of study compared [5] with Computer Science and Information Systems. SIGITE (Special Interest Group for IT Education) [6] is the ACM working group to define this standard. Worldwide IT service revenues amounted to $ 763 billion in 2009. [7]
