What happens when you enter Google/any URL on the browser?

??DNS Resolution

When you type Google(.)com into your browser, the first step is to resolve the domain name to an IP address. Your computer checks its local DNS cache to see if it has the IP address for Google(.)com stored. If found in the cache, it can skip the DNS server query and directly use the cached IP address, reducing the need for a DNS lookup.

??DNS Query

If the IP address for Google(.)com is not found in the cache or if the cached entry has expired, your computer sends a DNS query to a DNS server, requesting the IP address associated with the domain name Google(.)com

??DNS Server Response

The DNS server, which may be operated by your Internet service provider (ISP) or a public DNS service, responds with the IP address for Google(.)com This response is then cached on your local machine for future use.

??Establishing a Connection: With the IP address in hand, your computer initiates a connection to the Google server at that IP address, using the Internet and the specified protocol, such as HTTP or HTTPS.

??Sending a Request

Your browser sends an HTTP(S) request to the Google server, specifying the desired webpage. This request includes information about the webpage, your browser, and other relevant details.

??Processing the Request

Google's server receives the request and processes it, identifying the requested page, in this case, the Google homepage.

??Generating a Response

Google's server generates an HTML response for the Google homepage, including all the content that makes up the page, such as text, images, links, and more.

??Sending the Response

The server sends the HTML response back to your computer over the internet.

??Rendering the Page

Your web browser receives the HTML response and starts rendering the Google homepage. This process involves interpreting the HTML, loading and displaying images, and executing any JavaScript code included on the page.

??Displaying the Page

Finally, your web browser displays the Google homepage on your screen, allowing you to interact with it, perform searches, and navigate the web.

As previously mentioned, the DNS cache plays a crucial role in optimizing the process, as cached entries can reduce the need for repeated DNS queries, which helps improve performance and reduce latency in browsing.
