Have you
ever wondered what happens when you type www.google.com in your browser and hit enter?
Are you curious about what happens when you hit the enter
key?
If you were curious, this article is going to simplify that.
When you hit enter, there are a lot of things that go on at
the back, and finally you get the output in a very few microseconds.
Let me be brief about what happens in those few seconds.
1)
Your computer needs to be connected to the ISP (Internet
service provider).
Why ISP? ⇾An ISP is required to connect
to the internet.
2)
After this, your computer sends a request to DNS
(Domain name service). DNS sends back the IP address of the server that stores
the information on google.com.
DNS:
is like the phone book of the Internet. That stores the all-Domain names
with their IP address, which allows the browser to get the website’s IP address.
3)
After knowing the IP address, the computer
establishes a connection with the server through this IP address. The most frequently used connection type is TCP (Transmission control protocol).
TCP: is a communication standard that
enables application programs and computing devices to exchange messages over
the network.
4)
After establishing a connection, the browser now
sends a request for a web page, through some protocols to ensure a secure
connection.
Examples for the types of protocols are SSL
(secure socket layer), TLS (Transport layer security)
5)
The Server receives the request and sends a
response back, which includes HTML, CSS and JS that makes up the home page that
you searched for and then hit enter.
6)
And then, finally, the browser will render the page
and display to you.
