The Digital Age of Education
The Future of the Internet
Why did the Internet happen?
With everything the Internet has given us, it still has room for improvement. It has the potential to make a bigger presence in international affairs, the educational system, and society in general. It will have even more information available in the future, faster, and more reliable.
Websites Through Time
The biggest benefit of the Internet
Educators supplement textbook material with updated news and visual images or audio.
Students learn the collaborative process: crowd-sourcing
Digital Humanities: how to integrate the "old ways" in a "new school" kind of way.
Benefits of the Internet
Vast amount of information.
Revolutionizes technology: Apps, Cellphones, and Computers all have Internet.
Communication and information is faster and easier to access.
Online shopping, banking, schooling makes everything convenient.
Not only local commerce, but international!
Employment: Web Designers, Computer Techs & Programmers. Also, housewives and the disabled have greater opportunities.
First user friendly web browser. Everyone could search and see the same websites. This revolutionized the Internet because it began company websites and e-commerce.
Scientist and military experts were concerned about Soviet missile destroying nation's telephone system. In 1962, a scientist from M.I.T. named J.C.R. Licklider proposed a solution to this problem: a “galactic network” of computers that could talk to one another. Such a network would enable government leaders to communicate even if the Soviets destroyed the telephone system.
In 1965, another M.I.T. scientist developed a way of sending information from one computer to another that he called “packet switching.” Packet switching breaks data down into blocks, or packets, before sending it to its destination. That way, each packet can take its own route from place to place.
How did it all happen?
Most of the web's information is buried far down on sites, and standard search engines do not find it. Examples are government databases and libraries. Surface web is websites and info that standard search engines can find. Estimated that deep web is 400 – 550 times larger than surface web and growing exponentially. Estimated that 0.03% of information is on surface web and the rest is on the deep web.
The Deep Web
Four computers were connected to the ARPAnet. In the 70s, packet-switched computer networks multiplied, however, it became more difficult for them to integrate into a single worldwide “Internet.”
Tim Berners-Lee introduced the World Wide Web: an Internet that was not simply a way to send files from one place to another but was itself a “web” of information that anyone on the Internet could retrieve. This is Internet we know today.
By the 1970s
A computer scientist named Vinton Cerf developed a way for all of the computers on all of the world’s mini-networks to communicate with one another. He called his invention “Transmission Control Protocol,” or TCP. (Later, he added an additional protocol, known as “Internet Protocol.”
Birth of the
