this week I learnt about Information Technology (IT) which defined as any computer-based tool that people used to work with information and information-processing needs of an organisation.
IT has been divided into IT architecture and IT infrastructure. IT Architecture is to ensure the alignment of information and communications technology to business strategy. it is also used to explain and guide how an organization’s IT and information management elements work together to efficiently accomplish the mission of the organization.
On the other hand,IT infrastructure is the physical hardware used to interconnect computers and users including the transmission media, telephone lines, cable television lines, and satellites and antennas and also the routers, aggregators, repeaters, and other devices that control transmission paths. It also includes the software used to send,receive and manage the signals that are transmitted.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.
The advance of IT made the globalization happened. Globalization is defined as the integration and interdependence of economic,social,culture, and ecological facets of life. globalization 1.0 start from 1492-1800, globalization 2.0(1800-2000) and globalization 3.0(2000 to the present).
