Web vs. Internet Overview

Study Notes

The web (World Wide Web) is an interconnected network of web pages accessed using links.
The Internet is a vast connection of networks linking millions of computers globally, enabling communication between them.

The first website went live on August 6, 1991, with the address http://info.cern.ch/hypertext/WWW/TheProject.html.
It contained links to the WWW project, a description of hypertext, information about creating web servers, and links to other web servers.

Tim Berners-Lee invented the Web (WWW) in 1989 while at CERN.
His idea was to combine computers, data networks, and hypertext into a powerful and simple global information system.
He wrote his first proposal in March 1989 and the second in May 1990.
The WWW software was available to colleagues at CERN in March 1991.
By August 1991, the project was announced on Internet newsgroups, leading to global interest.
By the end of 1990, the first web server and browser were running at CERN using a NeXT computer.
To prevent the server from being accidentally shut down, Berners-Lee put up a label in red ink stating "This machine is a server. DO NOT POWER IT DOWN!!"
Berners-Lee had to recruit more developers to support the growing demand.
In 1993, NCSA released versions of the web browser for PC and Macintosh, which significantly increased the popularity of the World Wide Web.

The Internet relies on physical cables such as copper telephone wires, TV cables, and fiber optic cables.
Wireless connections, like Wi-Fi and 3G/4G, are also networks because they depend on these physical cables for access.

ARPANET was decommissioned in the 1990s.
Berners-Lee and his colleagues at CERN developed HTML (Hypertext Markup Language) and the URL (Uniform Resource Locator), which formed the first version of the World Wide Web.
In 1995, Microsoft launched Windows 95.
Online businesses like Amazon, Yahoo, and eBay emerged.
Java was created, enabling animations on websites and fueling new internet activity.
