Introduction of Internet
INTRODUCTION TO INTERNET
1. Internet is a vast network of computer networks. Born in 1964, the internet is a brain child of Paul Barren of the US Defence Research "Laboratory, is a standards based network of networks that enables diverse computers working in varying system environments, to communicate with each other. The real power of internet came to the fore when Tim Berner Lee created an internet application called world wide web (WWW) based on Hyper Text Markup Language (HTML) in march 1989 at European Particle Physics Lab in Germany, which supports
graphic and interactive content.
2. Types of Internet connections : (a) Email connectivity. (b) Dial-up shell account connectivity.
(c) Dial-up complete connectivity (also called TCP/IP connectivity.
(d) Leased line connectivity.
5. Components of Internet :
(a) Computer.
(b) Modem Modulator & Demodulator. Modem is one of the most important devices, which determines how fast or slow your Internet connection will be. This is a device used for connecting a device to a telephone line. It translate the computer language to that of the phone and also other way round.
(c) Software. The only other software required on the computer besides Window 95 is a Web browser, any popular browser like Internet explorer or Netscape navigator will do. All other software

4. Agencies and Functions.
(a) lnternetAssi ned Numbers Authorit IANA . Based at the University of southern California's Information Sciences Institute, IANA is the in charge of all unique parameters of the internet, including IP addresses. Each domain is associated with a unique IP address, a numerical name consisting of four blocks of upto three digits each. example 204.146.46.8, which systems use to
direct information through the network.
(b) Internet En ineerin Task Force IETF . The IETF is a large open international community of network designers, operators, vendors and researchers concerned with the evolution of the internet architecture and the smooth operation of the internet. It is open to any interested individual. The IETF is the protocol engineering and development arm of the Internet. The actual technical work of the lETF is done in its working groups, which are organized by topic into several areas (eg. routing. transport, security etc). Much of the work is handled via Mailing list. The
IETF holds meetings three times per year.
(c) National Information Centres N/Cs . There are a number of Nle located through out the Internet to serve its users with documentation, guidance, advice and assistance. As the Internet continuos to grow internationally we need for high quality NIC
functions increases.
World Wide Web WWW
5. Internet resources are managed and downloaded by World Wide Web servers. The web is a distributed hyper-text based information system developed at CERN by Tim Burners-Lee in 1989.

World Wide Web WWW
5. Internet resources are managed and downloaded by World Wide Web servers. The web is a distributed hyper-text based information system developed at CERN by Tim Burners-Lee in 1989.
6. The web refers to the information on the Internet. lt allows you to obtain information. It is based on the concept of hypertext and hypermedia, in which servers exist solely to link users to documents and multimedia files. Hypertext is a computer information containing text that can be linked with selected phrases. The links point to other documents or files. It basically the same as regular texts, but it contains connections within the text or other documents. The links in the text are called hyperlinks. Hypermedia takes hypertext another step to include images, sounds, and video with links that can be selected and viewed.
7, The web allows an easy interchange of hypermedia between networked environments. The web works under the client-server model. A web server is a program running on a computer whose only purpose is to serve documents to other computers when asked to. Information can be downloaded and uploaded to the web Hypertext Markup Language (HTML) is the language the web uses to create and recognise hypermedia documents.
Internet Connectivit Architecture
8. lnte-rated Services Di-ital Network lSDN. As the analog transmission and switching components were rendered obsolete by superior digital ones, a new set of protocols was needed to allow their full potential to be realised. lSDN provides framework for the development of these components and protocols. lSDN represents a iogical migration of the voice oriented IDN (integrated Digital Network) toward a network that serves multiple purposes voice, data, video, facsimile, and all other forms of electronic communication, regardless of the source.
lSDN can be Characterised in Two Wa s :
(a) As a bundle of services offered for the transmission of voice, data, and other forms of communication via the switched telephone networks of the world.
(b) As a set of protocols that defines a standard interface to the network, allowing many vendors to supply both hardware and software that take advantages of the services offered.
9.Remote Access services (RAS).
Ras connects remote or mobile machines to corporates machines.
Ras supports WAN connections, protocols, and security features.
