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 uses the standard Internet Protocol (TCP/IP). Every computer on the 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.
A special computer DNS (Domain Name Server) is used to provide a name to the IP Address so that the user can locate a computer by a name.
The Internet is accessible to every user all over the world.
The intranet is the system in which multiple PCs are connected to each other. PCs in the intranet are not available to the world outside the intranet. Usually, each organization has its own Intranet network and members/employees of that organization can access the computers in their intranet.
Each computer in Intranet is also identified by an IP Address which is unique among the computers in that Intranet.
Similarities between Internet and Intranet
Intranet uses internet protocols such as TCP/IP and FTP.
Intranet sites are accessible via the web browser in a similar way as websites on the internet. However, only members of the Intranet network can access intranet hosted sites.
In Intranet, own instant messengers can be used as similar to yahoo messenger/Gtalk over the internet.
Differences between Internet and Intranet
The Internet is general to PCs all over the world whereas the Intranet is specific to a few PCs.
The Internet provides wider and better access to websites to a large population, whereas Intranet is restricted.
Internet is not as safe as Intranet. Intranet can be safely privatized as per the need.
