Benefits of Extranet Introduction to Internet • The Internet is the global system of interconnected computer networks. • The Internet carries an unlimited range of information resources and services, such as the inter-linked hypertext documents and applications of the Web, electronic mail, telephony and file sharing. • The Internet becomes the main method in exchanging cultures and transferring knowledge between people. History of the Internet • The internet started off with research into what was then known as packet switching as early as the 1960s. • Packet switching was thought of as a better and faster method to transfer data than the hardware solution to the problem, the circuitry. • The package switching technology was essential to the development of ARPANET by the United States Military. • ARPANET is considered the first known group of interconnected computers the internet. This system used to transfer confidential data between the Military. What do we need to connect to the Internet? • To connect to the Internet we need the following 04 thing: Computer Modem Telephone line ISP(Internet Service Provider) • The computer is essential.

You access the IPS over the phone line and the IPS will connect you to the Internet. Internet Terminology • Asymmetric Digital Subscriber Line (ADSL) Broadband Internet connection who’s download and upload speeds differ. • ARPANET The acronym stands for Advanced Research Projects Agency Network. It became the world’s first packet switching network. Internet is the successor of ARPANET. • Browser Special software designed to read web pages. Often referred to as a Web Browser. Google Chrome, Safari, Mozilla and Opera are the most popular browsers. • Common Gateway Interface (CGI) A facility on your host’s server for running server- side scripts etc. • Domain Name The unique name that identifies an internet based web site.
