Electronics have a profound impact on various aspects of modern society and culture, such as communication, entertainment, education, health care, industry, and security. Information technology (IT) is the use of computers to create, process, store, retrieve and exchange all kinds of data[1] and information. IT forms part of information and communications technology (ICT). 2. An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users, and an IT project usually refers to the commissioning and implementation of an IT system.
