9. C. Web 3.0: (Read-write intelligent web)
•Uses AI, blockchain, and decentralized networks
to provide a more intelligent and personalized
experience.
•Data is more secure and user-controlled,
reducing reliance on big tech companies.
•Focus on smart applications that understand user
intent (e.g., AI-powered assistants).

13. The internet as we know it doesn’t exist until much
later, but internet history starts in the 1960s.
➢ In 1962, MIT computer scientist J.C.R. Licklider comes up with the idea for a
global computer network. He later shares his idea with colleagues at the U.S.
Department of Defense Advanced Research Projects Agency (ARPA).
➢ Work by Leonard Kleinrock, Thomas Merrill and Lawrence G. Roberts
on packet-switching theory pioneers the way to the world’s first wide-area
computer network.
➢ Roberts later goes on to publish a plan for the ARPANET, an ARPA-funded
computer network that becomes a reality in 1969. Over the following years,
the ARPANET grows.

14. • 1973: Robert Kahn and Vinton Cerf develop TCP/IP, enabling multiple
networks to connect while maintaining stability.
• Ethernet: Robert Metcalfe at Xerox creates a cable-based data transfer
system, initially called Alto Aloha.
• Hypertext & Unix: Ted Nelson proposes hypertext for organizing
network data, and Unix gains popularity for TCP/IP.
• USENET: Tom Truscott and Steve Bellovin create a Unix-based dial-up
system for data transfer over phone lines.

15. ➢Dave Farber develops a low-cost dial-up network project.
➢1981: 3Com (founded by Robert Metcalfe) launches Ethernet
products, enabling LANs.
➢1982: PhoneNet connects ARPANET and Telenet, expanding
global internet access and email communication.
➢Domain Name System (DNS) is created by Paul Mockapetris, Jon
Postel, and Craig Partridge to manage growing internet users.
➢1985: The first domain, symbolics.com, is registered.

16. ➢ In 1990, ARPANET is decommissioned. Tim Berners-Lee and his colleagues at CERN
develop hypertext markup language (HTML) and the uniform resource locator (URL),
giving birth to the first incarnation of the World Wide Web.
➢ A watershed year for the internet comes in 1995: Microsoft launches Windows 95;
Amazon, Yahoo and eBay all launch; Internet Explorer launches; and Java is created,
allowing for animation on websites and creating a new flurry of internet activity.
➢ In 1996, Congress passes the Communications Decency Act in an effort to combat the
growing amount of objectionable material on the internet. John Perry Barlow responds
with an essay, A Declaration of the Independence of Cyberspace.
➢ Google is founded in 1998.
➢ In 1999, the music and video piracy controversy intensifies with the launch of Napster.
The first internet virus capable of copying and sending itself to a user’s address book is
discovered in 1999.

17. ➢ 2000 sees the rise and burst of the dotcom bubble.
➢ While myriad internet-based businesses become present in everyday life, the Dow
Jones industrial average also sees its biggest one-day drop in history up to that
point.
➢ By 2001, most publicly traded dotcom companies are gone. It’s not all bad news
➢ 2000s see Google’s meteoric rise to domination of the search engine market. This
decade also sees the rise and proliferation of Wi-Fi — wireless internet
communication — as well as mobile internet devices like smartphones
➢ In 2005, the first-ever internet cat video. (YOUTUBE)

18. • On March 21,2006 Twitter was founded.
• In 2007, Tumblr is created.
• In 2008, NASA successfully tests the first deep space communications network
modeled on the Internet. Using software called Disruption-Tolerant
Networking (DTN), dozens of space images are transmitted to and from a
NASA science spacecraft located about more than 32 million kilometers from
Earth.
• In 2009, Internet for mobile phones was widely used. The boom of social
networks.
• In 2010, Instagram was founded.
• Online petitions were made to pass a bill for anti-piracy.
