When you type "https://www.google.com" into your browser and press enter, a lot of things happen behind the scenes to bring the Google homepage to your screen.?
Explained in simple terms:
First, your browser sends a request to a special computer called a DNS server, which helps translate the website's name, google.com, into a set of numbers called an IP address. This is similar to how you might look up a phone number in a phone book before making a call.
Next, your browser uses a protocol called TCP/IP to establish a connection with the server hosting google.com. This is like making a phone call to the number you just looked up.
There might be a security system called a firewall in place which checks if your request is allowed to pass through before reaching the server.
Once the connection is established, your browser sends a request asking for the Google homepage. This request is sent over HTTPS, which is a secure version of the normal request protocol, HTTP. This is like having a secret code that only the browser and the server know, to keep your request private.
Before the request reaches the server that actually stores the Google homepage, it might go through a device called a load-balancer. This distributes the incoming requests across multiple servers to make sure no single server gets overwhelmed.
The server that receives the request, called the web server, then sends back the Google homepage in the form of HTML, CSS, and JavaScript code. The application server processes any dynamic requests that the browser makes, like search queries and the database stores the information for the application.
In simple terms, a lot of different technologies work together to translate the website name you typed, fetch the webpage and deliver it to your browser for you to see.
