 Client and Server:

Request and Responses:

    When you  types a website address into your browser, your browser sends a request to the server, asking for the website's content.

HTML, CSS, and, JavaScript:

    The server responds by sending back the website's code which includes:

• HTML: This is the foundation of the webpage, defining its structure and content.
• CSS: This controls the visual presentation of the webpage such as, colors fonts and layout.
• JavaScript: This adds interactivity and dynamic behavior to the webpage, allowing it to respond to the user actions.

Browser Rendering:

     Your browser receives the code and the other resources from the server, then interpts and displays them as a webpage.

Domain Name and IP Address:

     Your type a domain name like "www.emp.com" into your browser, which is then translated into an IP address (a numerical value) that identifies the server hosting the website.

Protocols:

     The internet uses protocols like HTTP and TCP/IP  to facilate the exchange of data between the client and server.
