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
