Q:What is "Information Technology"

A:信息技術或資訊科技(英語:Information Technology,簡稱IT),是主要用於管理和處理資  訊所採用的各種技術總稱。它主要是應用電腦科學和通訊技術來設計、開發、安裝和實施資訊系統及應用軟體。它也常被稱為資訊和通訊技術(Information and Communications Technology, ICT)。


      Information technology (IT) is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware", according to the Information Technology Association of America (ITAA).IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information.

      Today, the term information has ballooned to encompass many aspects of computing and technology, and the term has become very recognizable. IT professionals perform a variety of duties 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 the 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.
     When computer and communications technologies are combined, the result is information technology, or "infotech". Information technology is a general term that describes any technology that helps to produce, manipulate, store, communicate, and/or disseminate information.
     In recent days ABET and the ACM have collaborated to form accreditation and curriculum standardsfor degrees in Information Technology as a distinct field of study separate from both Computer Science and Information Systems. SIGITEis the ACM working group for defining these standards. The Worldwide IT services revenue totalled $763 billion in 2009.
