Information technology (IT) is a general term that describes any technology that helps to produce, manipulate, store, communicate, and disseminate information.
Information technology, as the name suggests, are systems comprising of a number of components that work in conjugation to process information. The information to be processed can arise from within the organization or external elements that it deals with.
Technology can be thought of as the application of scientific knowledge for practical purposes. From the invention of the wheel to the harnessing of electricity for artificial lighting, technology is a part of our lives in so many ways that we tend to take it for granted. As discussed before, the first four components of information systems hardware, software, network communication, and data, are all technologies that must integrate well together.
Two Parts of Information Technology
There are two parts of information technology, they are described as thus:
Computer technology one of the parts of information technology is used to serve and connect people in the modern world. Desktops, laptops and mobile devices network the world together and perform multiple operations at once; however, this industry includes more than these machines. Individuals, communities, government and organizations rely on computer technology to produce or innovate the majority of things in their lives, such as food, services, entertainment, care, communication, education and transportation.
A computer is a programmable, multiuse machine that accepts data raw facts and figures and processes, or manipulates, it into information. Its purpose is to speed up problem solving and increase productivity. An example of computer technology is the development of a software program that allows people to accomplish work at home which has been automatically assigned from computers at their job location.
Unquestionably you’ve been using communications technology for Communications technology, also called telecommunications technology, consists of electromagnetic devices and systems for communicating over long distances. The principal examples are telephone, radio, broadcast television, and cable TV. In more recent times, there has been the addition of communication among computers which is what happens when people “go online” on the internet. Online means using a computer or some other information device, connected through a network, to access information and services from another computer or information device.
