Internet Global Connection
Wireless Internet Connection:
Let's understand this by taking an example as shown below in figure-
Now, narrow our focus to the essentials of our daily life: our home, our Wi-Fi connection, and how this connection brings the vast world of the Internet into our reach.
But for now, let's just focus on the fact that we have a home and we have Wi-Fi and this Wi-Fi essentially gives us Internet from the router.
You can see this little person at the bottom right corner working with a router next to him and this router is connected all the way to something called a modem.
This router is our gateway to the digital realm, but it's not alone in this journey. It's connected to something called a modem. If you've ever signed up for Internet service or switched providers, you've likely had someone install this mysterious device in your home.
This box (modem), serves as the link between your home and the Internet Service Provider (ISP) — that massive building we've seen before. The modem is like the bridge between your personal network and the vast expanse of the internet.
Inside this modem, there are signal towers that transmit requests for websites like Google.com. These signals travel back and forth along the wire connecting your home to the ISP.
Here want to point out something fascinating: while we often think of Wi-Fi as a magical wireless connection, at its core, everything is interconnected by cables.
Cables are the Internet Backbone:
Let's say we're in India and we want to access Google.com. From our home, through Wi-Fi, the connection flows to our router, then our modem, and finally to our ISP, which we'll position here.
Now, imagine that Google's servers are located in the USA. The request for Google's IP address and its files will traverse a physical undersea cable, known as a submarine cable. Yes, you heard that right! There are actual cables lying on the sea floor, connecting countries and continents.
This cable carries your request from India to the USA, where Google's servers reside. They respond by sending the requested files back through the ISP, retracing the cable's path all the way to your home.
Isn't it mind-boggling that there are tangible cables stretching across oceans, weaving together the Internet? Sometimes, disruptions like cable damage can temporarily interrupt our Internet service.
