Information Technology

Information technology (IT) is the application of computers and telecommunications equipment to store, retrieve, transmit and manipulate data, often in the context of a business or other enterprise. The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several industries are associated with information technology, such as computer hardware, software, electronics, semiconductors, internet, telecom equipment, e-commerce and computer services.

In a business context, the Information Technology Association of America has defined information technology as “the study, design, development, application, implementation, support or management of computer-based information systems”. The responsibilities of those working in the field include network administration, software development and installation, and the planning and management of an organization’s technology life cycle, by which hardware and software are maintained, upgraded and replaced.

Infrastructure

Information technology infrastructure is the integrated framework upon which digital networks operate. This infrastructure includes data centers, computers, computer networks, Database Management devices, and a regulatory system. In information technology, and on the Internet, infrastructure is the physical hardware used to interconnect computers and users. Infrastructure includes the transmission media, including telephone lines, cable television lines, and satellites and antennas, and also the routers that transfer data between disparate transmission technologies. In some usages, infrastructure refers to interconnecting hardware and software and not to computers and other devices that are interconnected. However, to some information technology users, infrastructure is viewed as everything that supports the flow and processing of information. Infrastructure companies play a significant role in evolving the Internet. They influence where the interconnections are placed, where data is made accessible, and also how much information can be carried, and how quickly.
