I am very much excited to say that internet made our lives simpler. In early ages machines have been part and parcel of our lives. But Internet been so revolutionary that every tech giant will surely use internet for some or other purpose. Today I am going to show how internet works. This is going to be really interesting and worth a read. Let’s go!
Basic components that involved in our discussion
- DNS and ISP
Deep dive in to working of internet
When I asked my colleague about this wonder. He said internet is simply a wire. I was shocked! I am sure everyone can guess about this. He further continued that it is a flow of data. That makes some sense right. Understanding what actually internet is! makes this blog a complex one. Let’s keep it simple and interesting. We are going to discuss only the basic beautiful things.
Let’s take our journey through a real time experience to make this a amazing learning. When you open your internet browser and request your browser for this url (Uniform Resource Locator) let it be https://www.google.com. After few seconds you see that your browser shows up the website you wanted. Between your request and loading of the website takes internet to do its job. Here comes the word CLIENT which is nothing but the computer or the browser which is requesting internet to load some website. This flows in the form of data packets. Here we are going to discuss about two amazing things called MODEM and ROUTER. They are completely different in their own way. Look at the below picture
Modem by its name acts as a modulator and de-modulator. Modem is used to communicate with internet. Modem changes signals between analog and digital. Computer information is stored digitally but while transformation need to converted in to analog. If your question is why Check this out
Did you ever hear something like wifi-router from others. Yes your near to the vicinity of understanding what a router does! Router will have provision for ethernet cable so that you can connect this ethernet cable to your computer. But most used are wifi-Routers which transmit through free space without any cables required.
So you can tell router and modem have great difference.
ISP or Internet service providers are used to get internet access to your locality. Now you should be using ISPs like Beam, Airtel , Jio and so many. These simply charge from the user and give access to the internet.
DNS or domain name system does what it’s name really specifies. It works on a systematic way of searching for the domains and converting those domain names (Human understandable) into their corresponding IP(Internet protocol) addresses so that the internet can do its job of requesting data from the server.
In this way if every component of this system does it’s job perfectly then finally your website shows up successfully on your web browser. Already sweating of typing heavily. We haven’t gone in depth and only had a very basic overview of how internet works. Feeling hyped reminding myself about many amazing things through out the blog.
