Takeaways

  • 🌐 A website is a collection of web pages and can be as simple as a single HTML page.
  • 🏠 To make a website accessible to others, it needs to be hosted on the Internet, not just on a local machine.
  • 💻 The first requirement for hosting a website on the Internet is a computer with an Internet connection.
  • 🔄 An additional necessity for making a website available online is a web server.
  • 🤔 A web server is a piece of software that listens and responds to user requests over the Internet.
  • 🏢 The client-server model is fundamental to how websites work, with the client (browser) sending requests and the server (web server) providing responses.
  • 🔑 An Internet service provider assigns a unique IP address to a computer when it connects to the Internet.
  • 🚪 A web server acts as a listener, waiting for and responding to incoming requests, much like someone at home to answer the door.
  • 🌐 The browser, as a client, sends a request to the server, which is identified by an IP address, to access web pages.
  • 🔍 The script introduces the concept of a web server and sets the stage for further exploration in upcoming videos.

  • What is the problem if a web server is not running on a computer hosting a website?

    -If a web server is not running, it cannot listen to and respond to incoming requests, meaning users cannot access the website.

  • How does the browser know where to send a request when a user enters a website's address?

    -The fundamental function of a web server is to listen for incoming requests from clients and respond by serving the appropriate web pages or resources.

  • Why might a website's address be difficult to use if it's just an IP address and file name?
