The document discusses the history and components of the Internet. It provides an overview of how the Internet developed from early research networks in the 1970s to becoming a global, commercial system by the mid-1990s. It also describes important aspects like the TCP/IP protocol, the invention of the World Wide Web in 1989, and popular applications and search engines used on the Internet today.

4. Introduction to
Internet
• The Internet is the global system of interconnected computer networks that use
the Internet protocol suite (TCP/IP) to link billions of devices worldwide.
• It is a network of networks that consists of millions of private, public, academic,
business, and government networks of local to global scope, linked by a broad
array of electronic, wireless, and optical networking technologies.
• The Internet carries an extensive range of information resources and services, such
as the inter-linked hypertext documents and applications of the World Wide Web
(WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.

5. History of
• Early international collaborations on the ARPANET were rare.
• European developers were concerned with developing the X.25 networks.
• In 1982, the Internet Protocol Suite (TCP/IP) was standardized, which permitted worldwide
proliferation of interconnected networks.
• Access to the ARPANET was expanded in 1981 when the National Science Foundation
(NSF) funded the Computer Science Network (CSNET). In December 1974, RFC 675
(Specification of Internet Transmission Control Program) by Vinton Cerf, Yogen Dalal, and
Carl Sunshine used the term internet as a shorthand for internetworking and later RFCs
repeated this use.
• Notable exceptions were the Norwegian Seismic Array (NORSAR) in June 1973, followed in
1973 by Sweden with satellite links to the Tanum Earth Station and Peter T. Kirstein's
research group in the United Kingdom, initially at the Institute of Computer Science,
University of London and later at University College London.
• TCP/IP network access expanded again in 1986 when the National Science Foundation
Network (NSFNet) provided access to supercomputer sites in the United States for
researchers, first at speeds of 56 kbit/s and later at 1.5 Mbit/s and 45 Mbit/s. Commercial
Internet service providers (ISPs) emerged in the late 1980s and early 1990s.. By 1995, the
Internet was fully commercialized in the U.S. and then whole world.

6. WORLD WIDE WEB
• The World Wide Web (WWW) is an information space
where documents and other web resources are
identified by URLs, interlinked by hypertext links, and
can be accessed via the Internet.
• The World Wide Web was invented by English
scientist Tim Berners-Lee in 1989. He wrote the first
web browser in 1990 while employed at CERN in
Switzerland.
• It has become known simply as the Web. The World
Wide Web was central to the development of the
Information Age and is the primary tool billions of
people use to interact on the Internet.

7. Google
• Industry : Internet, Computer
software.
• Founded : September 4, 1998; Menlo
Park, California.
• Founders : Larry Page, Sergey Brin.
• Headquarters : Googleplex,
California, U.S.
• Key people : Sundar Pichai (CEO)
• Number of employees : 57,100 .
• Slogan : Don't be evil .

10. The Internet protocol suite is the computer networking
model and set of communications protocols used on the
Internet and similar computer networks.
It is commonly known as, because its most important
protocols, the Transmission Control Protocol (TCP) .
The Internet Protocol (IP) were the first networking
protocols defined during its development. It is
occasionally known as the Department of Defense (DOD)
model, because the development of the networking model
was funded by DARPA, an agency of the United States
Department of Defense.
TCP/IP provides end-to-end data communication
specifying how data should be packetized, addressed,
transmitted, routed and received.

11. The ideal telecommunication network has the following
characteristics: Broadband
Multi-media,
Multi-point,
Multi-rate, etc.
It is also economical implementation for a diversity of
services (multi-services).
The Broadband Integrated Services Digital Network
(B-ISDN) was planned to provide these
characteristics. Asynchronous Transfer Mode (ATM)
was promoted as a target technology for meeting
these requirements.

12. A local area network (LAN) is a computer network that interconnects
computers within a limited area such as a residence, school,
laboratory, university campus or office building and has its network
equipment and interconnects locally managed. By contrast, a wide
area network (WAN), not only covers a larger geographic distance,
but also generally involves leased telecommunication circuits or
Internet links.
Ethernet and Wi-Fi are the two most common transmission
technologies in use for local area networks. Historical technologies
include ARCNET, Token ring, and AppleTalk.
Wi-Fi or WiFi is a technology that allows electronic devices to connect
to a wireless LAN (WLAN) network, mainly using the 2.4 gigahertz
(12 cm) UHF and 5 gigahertz (6 cm) SHF ISM radio bands. A WLAN is
usually password protected, but may be open, which allows any
device within its range to access the resources of the WLAN network.

13. Applications of Internet
• Communication : whatsapp, hike.
• Research : google, wiki, exploring the
world.
• Education : topper v , meritnation.
• Financial Transaction : banking.
• Online Shopping : amazon, flipkart .
• Entertainment : latest movies, games.
