Internet was started in 1970s as ARPANET.
• In 1970s United States defense ministry setup their network to share military information’s. Later a project called ARPANET was started to explore the possibilities of networking. Then later, US based universities were also involved in the ARPANET and they also started their networking along with US defense ministry. After the successful research of ARPANET, it was dissolved and the global network was called as Internet.
• The Internet of the 1980 was not only used for research purposes, but also for archiving and publication of general information.
• In the 1990, the American Government and commercial organizations were added rapidly to the fast expanding network.
• Now, the commercial possibilities were also introduced in the internet and gradually, it has come up to today’s state. B to B ->Business to Business ->target of businessB to C -> Business to consumerC to C -> Consumer to consumer -> auction sites, ebay.com bazee.com
That growth can also be explained by the user friendly software and of course the commercial side. At this moment there appear to be approx. 1.15.75 million users around the world.
What is Internet?
Internet is the large world wide networks of computers (the global network of different sub network) that facilitate data, communication services, file transfer, electronic mail, the World Wide Web and newsgroup with the common protocols.
Internet Services and ToolsEmail : sending electronic messages.
News : Discussion group on virtually every subject.
Telnet : remote login
FTP : transfer of files from one computer to another
Gopher : a method of searching for various text-based Internet recourses.

CU-SeeMe: a video conferencing system that allows users to send and receive sound and pictures simultaneously over the Internet.
WWW (World Wide Web)
The www is the brainchild of Tim Berners Lee a CERN who had the idea of creating an electronic web of research information. The web is currently the fastest growing Internet information system, with new sources being added regularly. The Web relies on a set of protocols, conventions and software to operate. The web is a distributed system of delivering linked documents over the Internet. It is called a distributed system because information can reside on different computers around the world, yet be easily linked together using hypertext. The Web uses hypertext, to create links from one resource to another. A hypertext link is usually displayed by highlighted and underlined text on the page. A hypertext link or hyperlink can also be graphic that acts as a button lining to another resource.
World Wide Web StandardsHypertext Transfer Protocol (HTTP) it is the standard protocol used
Meta-search Engines
A web meta-searcher is a tool that helps users locates information available via the World Wide Web. Web meta-searchers provide a single interface that enables users to search many different search engines, indexes and databases simultaneously.
Internet access

Extranet
An intranet (Internal TCP/IP Network) that has been selectively opened to a firm's supplier, customers is called Extranet.
Entranet
An Intranet can be defined as a network connecting an affiliated set of clients using standard Internet protocols, esp. TCP/IP and HTTP or as an IP-based network of nodes behind a firewall, or behind server firewalls connected by secure, possibly virtual, network.
Hypertext
The Hypertext allows for the integration of text, graphics, audio and video on a Web page. This can make it very easy to browse and very exciting to view. A web page may have colorful graphics integrated with textual information. Links on a webpage may take you to other web pages, recorded sounds, or digital video clips. A single click on any hyperlink allows you to follow the link to the specified resource.
