Information technology can refer to both the organizational unit of a company or organization, or the physical hardware and software and information that is used by a company to perform its functions. In this age of computers and the internet, it is simply not an option to operate a business without information technology in one form or another. Computers, networks, databases, e-mail, and websites are all forms of hardware and software that aid in producing, manipulating, storing and disseminating information. That information is necessary to maintain an edge against competition, help to advertise a business, and maintain adequate documentation about the company, its customers and it’s processes.
