Study Notes

Hyperlinks and the Web

Hyperlinks are connections from one HTML page to another, facilitating navigation on the internet.
Tim Berners-Lee developed the Hypertext Transfer Protocol (HTTP) and the Universal Resource Identifier (URI) system in 1990.
URI, or URL, is the unique address used to access web pages.
HTML documents are communicated via HTTP, enabling browsers to interpret and display content.
Berners-Lee's vision was to create a universal space for sharing information through hyperlinks.

Introduction of Web Browsers

Nicola Pellow created a simplified browser that could operate on any computer, working alongside Berners-Lee at CERN.
In 1993, Marc Andreessen launched Mosaic, the first user-friendly web browser from the National Center for Supercomputing Applications.
Mosaic allowed point-and-click browsing and was notable for displaying images alongside text.

Internet Protocols

Bob Kahn and Vint Cerf proposed a method for sending data packets in a digital 'envelope' called a datagram in 1974.
Only the intended recipient can open the datagram; the address is readable by all devices.
The Internet Protocol (IP) was developed alongside Transmission Control Protocol (TCP) to ensure proper data routing across the internet.
Every internet-connected device has a unique IP address.

Domain Name System (DNS)

DNS, developed in the early 1980s, translates complex IP addresses into easily memorable names, like a phone book for the internet.
Paul Mockapetris and Jon Postel invented DNS at the University of Southern California, aiding the growth of the World Wide Web.

Differences Between the Internet and the World Wide Web

The internet is the physical infrastructure connecting devices, while the World Wide Web is a system for accessing information via hyperlinks.
Tim Berners-Lee conceptualized the "web of information" in 1989, emphasizing document connectivity.

Evolution of Digital Technology

Digital technology has rapidly advanced from 1940 to 2020, merging physical and virtual realms.
The current digital era prioritizes transforming information storage from physical to digital formats.

Impact on Society

Digital technology influences various societal aspects including:
- Enhanced communication and connectivity
- Greater access to information
- Economic growth and increased efficiency
- Improvements in healthcare and medicine
- Advances in environmental sustainability
- Education and lifelong learning opportunities
- Facilitation of scientific research and innovation
