• Clients are software that access webservers.
  • Browsers are clients.
    Browsers send a request to a webserver, and the webserver responds by sending back html code to the browser.
    The browser uses the html code to construct and display the webpage.
  • Clients can be "desktop" clients, or "browser" clients.
    Desktop clients are sofware that are installed directly onto your computer.
    Browser clients are software you load from some internet site by conecting to it with your browser.
• A webserver is software that sends/delivers html code to your browser/client
  that results in displaying a webpage.
  • When you use a browser to connect to some internet site, whatever.com,
    that site is a webserver, and will send an html file back to your browser. The browser will use the html to build/display the webpage.
  • Webservers can be located and accessed on the internet, or they can be local on your personal computer.
    • A local webserver can be built by creating a LAMP stack.
      is a "stack" that is used to create a webserver.
