In this chapter, we will see what is Internet and Intranet, as well as discuss the similarities and differences between the two.
It is a worldwide/global system of interconnected computer networks. It can be defined as a global network of over a million computer networks. It uses the standard Internet Protocol (TCP/IP). Every computer in Internet is identified by a unique IP address. IP Address is a unique set of numbers (such as 220.127.116.11) which identifies a computer’s location. Any information on any subject can be obtained easily on the Internet.
A special computer DNS (Domain Name Server) is used to provide a name to the IP Address so that the user can identify the location of a computer by a name. For example, a DNS server will resolve a name https://www.wisdomjobs.com to a particular IP address to identify uniquely the computer on which this website is hosted.
Internet is accessible to every user all over the world.
Intranet is the system in which multiple PCs are connected to each other. These are not available to the world outside the intranet. This is helpful in individual organizations where it has its own Intranet network and members/employees of that organization can access the computers through their intranet.
Each computer in Intranet is also identified by a unique IP Address among the computers in that Intranet.
