Internet basically utilizes the convergence of computers and communication technologies are making studies over last thirty years in an unprecedented way.
Communication and the data transfer are increasing exponentially. A major achievement was when the first fibre capable of handling 40,000 telephone calls simultaneously was made operational in 1988 hundreds of gigabytes per second ((GCPs) data rates have now become possible to the fibre links spread all over the surface of earth including the ocean bed. It was in 1990 that APRANET was created into a public network and opened to all citizens. The formal book to Internet was registered when Internet society was chartered in 1992.
So the official age of Internet is 9 years. Internet is great because it found wide spread applications and it provided utility and services to the common man in the society. The first requirement was to develop the capabilities of transferring files and data from one computer to another. For this purpose a worldwide network of computers had to be established in such a way that any computer anywhere in the world could be connected to any of the millions and billions of computers. It is a web woven by the spider. Any pointer on the spider web is connected to all other points through portal either of number of cocentric rings or of spokes—like structure or both.
No wonder than that the Internet infrastructure was christened as World Wide Web (WWW). Internet gave birth to Intranet—a network within a large orgainzation using the same protocols as the Intranet. Intranet enabled the organization to increase efficiency, productivity and quality of product nets and services Intranets. Intranets could easily be connected to Internet since both used standards protocols when one Intranet gets connected to other Internet.
It becomes Extranet. E-mail In 1970 Ray Thomolinson, a programmer made history when he sent the world electronic mail the E-mail was addressed to himself and the body read the message “QWERTUIPO” and testing 1-2-3. Two years later in order to make e-mail easier TCP/IP, the language of internet came to existence. Gradually many contributed to the revolution by adding such features as sending attachment (pictures, sound clip etc.). The development of web browser gave a big boost to the use of e-mail in the e-commerce age. Throughout the 1990s the internet continued to witness a dramatic surge in traffic as people found wide application for mail ranging from messaging to advertising and active interaction between internet group.
Hotmail, the most well known e-mail portal was purchased by Microsoft in Jan 1998. Its success led to the emergence of other free portals such as Yahoo mail etc. Now there is a move in some form to make e-mail a paid service. However e-mail to some extent could dislodge overdependence on telephone and portal department. Lot of innovation is still alongside e-mail, like voice mails, sms, instant, messengers, web enabled services internet telephony etc. Email Growth Path In 1969 the birth of APRANET, the precursor of the present internet in 1971 Ray Tomlinson sends first ever email 1979. Eomoticoms bring life into otherwise boring computer newsgroup in 1982 TCP/IP introduced and Internet birth. In 1984 William Gibson uses the World Cyber space in his book Newsmancer in 1991 WWW is officially created by Tim Berner Lee at CERN Switzerland 1993 first graphical web Browser Mouse released for public use leading to concept of net surfing.
In 1996, 150 countries connected via internet and 40 million people get online in 2000. In the whole world more than 4 million e-mails were sent every day. 7 million new web pages were created on the web E-mail attraction is ever growing as computers are becoming more common and reaches to the interior of the villages.
How E-mail Works (1) Ready Internet connection. (2) E-mail client software installed in your computer. (3) Open the e-mail client which bridges your computer and the email server. The e-mail converts our typed text message into a suitable format that mailing server can understand and protect your e-mail from being intercepted. (4) The typed message is passed along to an SMTP server which scans; once located, the SMTP server sends the mail to the final destination. (5) From your local mail server, the mail is passed along to the recipient’s mail server.
(6) After the server receives the message it is internally transferred. (7) Using the POP3 protocols, the e-mail clients connect with the mail server and down load and store all incoming messages.
