The web

• Web was started by Tim Berners-Lee:
  • began as a way to distribute data on “cards” that were linked with “hyperlinks”
  • was instituted later as the “World Wide Web”
  • the language of webpages is HTML
  • HTML is input as a plain text document that is then interpreted and converted into web content for visual consumption
    • when we write HTML we put it inside of a file with the extension .html
    • so, web browsers are basically just “HTML readers”
  • URLs can be thought of as paths to HTML files:
    • http:// (protocol) + example.com (server) + /magic-cake.html (path to an HTML file)
    • Browser uses URL to request HTML file from server and then display the HTML
