[Applause] [Music] oh no kitty we have lost the internet connection oh no hmm don't worry i think it will get back in a while hey friends kitty and i are sending our halloween pictures to our friends but unfortunately we lost our internet connection and i'm sure you already know how it feels when that happens as it's difficult to imagine our lives without the internet nowadays wait a minute that's an excellent topic to explore hello friends have you ever wondered what the internet exactly is and how it works i'm sure you did so by the time
the internet reconnects let's search the world of the internet and learn how it works zoom in well when i was young i believed that the internet was some magic trick created by a secret group of magicians which makes it float through the clouds [Music] but when i came across its actual definition i understood that it is a network that connects millions of computers worldwide but the important question still remains the same how does this magic happen imagine you and your friend want to share a picture or some other essential document with each other and to
do so the first thing you both will need are computers that are connected in a network with the help of the internet then once you establish this connection you visit the website using a browser log into your account type your message or attach the file you wish to send and finally when everything is done you press the send button and voila it's done sounds easy right well what looked so easy at first glance has a complex system working behind it yes my friends the messages you send are actually enormous in size and it's very hard
for the internet to carry such a massive packet to its destination so to make it easier this huge packet is broken down into smaller packages and then they are moved further to the receiver with the help of an essential device called the router and what is a router a router is a networking device that helps in the transfer of data packets between computer networks in other words from a sender to the receiver but how well it does with the help of an internet protocol or an ip address oh no now what's an ip address so
many technical terms but let me explain just like you have your home address every server has its unique address called the ip address that allows a system to be recognized by other systems connected via internet protocol when the packets are received by the router the router reads the ip address information mentioned on the package and then sends it to the correct path to reach its destination by following certain rules yes my friends just like we have traffic rules to protect us from any accidents the internet has some rules and regulations as well called the tcp
tcp is a set of protocols developed for the internet to get data from one network device to another and by following these protocols the data gets delivered in the best possible way to its destination without any problem and issues when these packets finally arrive at the receiver's router they are put together according to the instructions and that's how your friend's computer receives your message and believe me all this happens within just a fraction of seconds isn't it really magical friends trip your time did you know the first ever email was sent in 1971 also it
is estimated that four billion out of the seven billion people on earth are already online and thanks to the internet you can see your most favorite show called the doctor binock show hope you enjoyed today's episode until next time it's me dr by nox zooming out [Music] ah never mind hey kids you liked my videos didn't you before you go don't forget to click on the subscribe button and the bell so you won't miss out on my latest videos see you
