Information technology (IT) is "the study, design, development, implementation, support or management of computer-based information systems An Information System is any combination of information technology and people's activities using that technology to support operations, management, and decision-making. In a very broad sense, the term information system is frequently used to refer to the interaction between people, algorithmic processes, data and technology. In this sense, the, particularly software applications and computer hardware", according to the Information Technology Association of America The Information Technology Association of America is a leading industry trade group for information technology companies. The Association's membership contains most all of the world's major ICT firms and accounts for over 90% of ICT goods and services sold in North America (ITAA).[1] IT deals with the use of electronic computers A computer is a programmable machine that receives input, stores and manipulates data//information, and provides output in a useful format and computer software Computer software, or just software, is a general term primarily used for digitally stored data such as computer programs and other kinds of information read and written by computers. Today, this includes data that has not traditionally been associated with computers, such as film, tapes and records. The term was coined in order to contrast to the to convert Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways. For example, the computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks. Similarly, the operating system is predicated on, store Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all, protect Data security is the means of ensuring that data is kept safe from corruption and that access to it is suitably controlled. Thus data security helps to ensure privacy. It also helps in protecting personal data, process Computer data processing is any process that uses a computer program to enter data and summarise, analyse or otherwise convert data into usable information. The process may be automated and run on a computer. It involves recording, analysing, sorting, summarising, calculating, disseminating and storing data. Because data is most useful when well-, transmit Data transmission, digital transmission or digital communications is the physical transfer of data over a point-to-point or point-to-multipoint transmission medium. Examples of such media are copper wires, optical fibres, wireless communication media, and storage media. The data is often represented as an electro-magnetic signal, such as an, and securely Classified information is sensitive information to which access is restricted by law or regulation to particular classes of persons. A formal security clearance is required to handle classified documents or access classified data. The clearance process requires a satisfactory background investigation. There are typically several levels of retrieve Information retrieval is the science of searching for documents, for information within documents, and for metadata about documents, as well as that of searching relational databases and the World Wide Web. There is overlap in the usage of the terms data retrieval, document retrieval, information retrieval, and text retrieval, but each also has information Information, in its most restricted technical sense, is an ordered sequence of symbols. As a concept, however, information has many meanings. Moreover, the concept of information is closely related to notions of constraint, communication, control, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, and representation.

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 A computer network, often simply referred to as a network, is a collection of computers and devices connected by communications channels that facilitates communications among users and allows users to share resources with other users. Networks may be classified according to a wide variety of characteristics. This article provides a general and information databases A database consists of an organized collection of data for one or more uses, typically in digital form. One way of classifying databases involves the type of their contents, for example: bibliographic, document-text, statistical. Digital databases are managed using database management systems, which store database contents, allowing data creation. A few of the duties that IT professionals perform may include data management The official definition provided by DAMA or Boucher: "Data Resource Management is the development and execution of architectures, policies, practices and procedures that properly manage the full data lifecycle needs of an enterprise."[citation needed] This definition is fairly broad and encompasses a number of professions which may not, networking, engineering computer hardware A personal computer is made up of multiple physical components of computer hardware, upon which can be installed an operating system and a multitude of software to perform the operator's desired functions, 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 ABET, Inc., formerly the Accreditation Board for Engineering and Technology, is a non-profit organization that accredits United States postsecondary degree programs in applied science, computing, engineering, and technology. Accreditation is intended to certify the quality of these programs. There are over 2,800 programs accredited at over 600 and the ACM The Association for Computing Machinery, or ACM, is a learned society for computing. It was founded in 1947 as the world's first scientific and educational computing society. Its membership is more than 92,000 as of 2009. Its headquarters are in New York City have collaborated to form accreditation and curriculum standards[2] for degrees in Information Technology as a distinct field of study separate from both Computer Science Computer science or computing science is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems. It is frequently described as the systematic study of algorithmic processes that create, describe, and transform information. Computer science and Information Systems Information Systems is historically defined as a 'bridge' anchored between the business world and computer science, but this discipline is slowly evolving towards a well-defined science. Typically, Information Systems (or IS) include people, procedures, data, software, and hardware (by degree) that are used to gather and analyze information. SIGITE[3] is the ACM working group for defining these standards. The Worldwide IT services revenue totalled $763 billion in 2009.[4]
