- 🤔 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.
