I think it’s fair that most of us can’t imagine what it’d be like to live without the internet.How many of us can stay without internet for just one month today? Tough, right? (Yea, I thought so) With the internet as ubiquitous as it is, how many of you have actually wondered what the internet is and how it works? It’s something I’ve wondered about and today in this blog I am gonna tell you about what is internet and how it works..

So, the Internet, sometimes called simply "the Net," is a worldwide system of computer networks -- a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers).

But how it works let's talk about it..

It works by using a packet routing network that follows Internet Protocol (IP) and Transport Control Protocol (TCP) . TCP and IP work together to ensure that data transmission across the internet is consistent and reliable, no matter which device you're using or where you're using it.

Let's learn it by an example.. For example, When you opened your email, your email application sent a request to your email provider (for example, Gmail) through your laptop’s Network Interface Card to your Wireless Access Point (WAP) using your local WiFi. The WAP then sent the request through a wire to the local router. The local router took that request and sent it to another router, which then sent to another router, and another router, all the way through a chain of routers. There, it ended up at a Google data center (because you use Gmail). Google then processed your request to get any new emails that had come in since you last loaded your email. They packaged up your new, unread emails in a digital package called a “response,” and sent that package back to the same address (your laptop) that requested the updates. The data was transferred from the Google data center through multiple lines and reached your home router/modem, which made the data available over your home WiFi.

And that all happened in the blink of an eye. It’s pretty amazing how the internet works, isn’t it? So the next time someone asks, “what is the internet” or “how does the internet work?” hopefully you can use this simple explanation to help them..
