– This global system consists of a number of public networks, private, business, govt., academic networks both with local and global scope.
– A broad system of wireless, electronic and optical technologies are what that keeps these networks in links with each other.
– A wide range of services as well as information is carried all over the world by the internet.
– The things carried over might include hypertext documents of WWW (i.e., world wide web) and other e – mail supporting infrastructure.
– A number of traditional communications media (includes music, telephone, and television and film etc.) have been redefined and reshaped by the internet.

Differences between Internet and Intranet

– Internet is the global connection while in Intranet only a certain number of internet protocols can communicate.
– Intranet is used where there no interference from outside IPs.
– Usually, the Intranet website can be accessed by the members of the organization who have the legal authorization i.e., the ID and the password.
– The servers and the websites used by an Intranet are often crucial for the IT of the organization.
– Thus, an Intranet lets the members of an organization stay connected to the work no matter where they are and what time it is.
