Browsing the web
Enter Google.com, who's this google.com
This question gets asked all the the the the same as the the the the same as the Internet Service Provider. ve Internet.
ISP get the request and send them to DNS (Domain Name server) server, it's like a phone book.
It has the list of all these URLs like google.com and have the address of them
DNS send off the request back through ISP
Web browser like Google Chrome in the case gets 172.217.7.23
We recevie IP address
Anything that's connected to the Internet have it own address (each laptop work now have IP address)
This Ip address allows the Internet to work
Once we know the IP address, the browser sends off another request to Google Server
Google Server say, oh np let me give you my HTML, CSS, JS
Then HTML, CSS, JS would is sent to the browser
Then browser would show the formal Google page
For the above three steps,
If we can skip the first step
Send the IP address directly to Google Server in the second step?
You can also get the third step of formal Google page

Develper Tools via View-Developer

IPS is connected to Internet backbone
All the files would go through this submarine cable (physical cable goes the bottom of see floor)
