The Internet and the World Wide Web
The Internet is the largest wide area network (WAN) comprising a vast number of interconnected networks, and it enables users to share information and resources across the world.
History of Internet Introduction:
In 1968 DARPA started the project ARPANET for defense labs and Universities. The underlying protocol for the communication was NCP. With period of time the network became congested and in 1973 it was decided to merge the networks and a common protocol for communication in 1981 as the standard emerged known as TCP/IP. Then in 1984 a merged network of networks called CSNET emerged. Later ARPNET and CSNET network and other network were merged in late 80’s and TCP/IP was communication protocol.
Reason for Internet Establishment:
Internet was established to enable two computers to communicate with each other. It helped in establishing an environment where research labs, defense labs, government departments can communicate at fast rate during the live environments of world war. It helped people in exchanging information using file transfer protocol. But with period of time as more and more users start joining the network, each network started getting congested, so the reach of the network and better performance of the network was increase by merging the networks and the network was known as Internet.
Underlying technology for Internet:
The underlying technologies for internet is TCP/IP for communications, HTTP based websites helps in enabling in writing the websites in common text and media format. Java based applets URL’s can be launched from the browser which are system independent.
Relationship between WWW and Internet:
The World Wide Web or WWW is the single largest and populist sub network of the Internet which also known as The Web and it was born in 1989 and it was supported by HTTP. So people can view web pages that may contain text, images, videos, and other multimedia and navigate between them using hyperlinks with the help of browsers. There are over 30 billion public web pages on the Web.
Key factors for WWW growth:
Support of URI based websites which could be accessed by using web browsers of Mozilla, Internet Explorer etc. It supports network protocol (HTTP) used by native W3 servers giving performance and features not otherwise available. It supports markup language (HTML) which every W3 client is required to understand, and is used for the transmission of basic things such as text, menus and simple on-line help information across the net;
