"From Non-Tech to Tech: How I Finally Understood What Happens When You Type Google.com"

Day 1: Demystifying the Internet - A Non-Tech Background Journey

Hello everyone! 👋 This is my first post here, and I'm excited to share my learnings from my tech journey.

Being from a non-tech background, understanding "What is the Internet & how does it work" was challenging. Thanks to my mentor @trainwithshubham, these concepts are now clearer. I'll be sharing daily insights I've learned!

🌐 What is the Internet?

Think of the internet as a global postal system - it's a massive network of connected computers worldwide that can communicate with each other.

🔑 Key Internet Jargon:

A. Servers & Clients:

  • Your laptop/phone is a client (requests information)
  • Computers storing websites are servers (serve information)
  • Servers live in Data Centres (like Google's and Amazon's massive server buildings)

B. Protocols (TCP/IP):

  • The "rules of the road" that computers follow to understand each other

C. DNS (Domain Name System):

  • The "phonebook of the internet" translates google.com into numerical IP addresses

🚀 How the Internet Works: The Google.com Journey

1. The Request

I open my laptop (client) and type "google.com"

2. DNS Lookup - Finding the Address

My laptop asks: "Where is google.com?" The DNS server responds with Google's IP address.

3. Local Travel - ISP & Routers

My request (with my IP + Google's IP) goes through my Internet Service Provider's routers.

4. Internet Backbone - The Highway

The request travels through fibre-optic cables under oceans and across continents.

5. Arrival at Google's Server

Google's server receives my request and prepares the homepage.

6. The Return Trip

Google's data packets find their way back to me, possibly taking different routes.

7. Display Magic

My browser reassembles all packets and displays Google.com!

💫 Conclusion

The internet is a cooperative ecosystem of devices, ISPs, routers, and servers, all following shared rules to move data at light speed. Next time you load a webpage, remember this incredible journey!
