Hello my dear students and friends, in today's blog, what is internet? You will get information about different types of devices and some terms associated with it. So let's know without delay -
The Internet is a network of networks. If said in very simple language, the Internet is such a bunch of wires spread all over the earth, through which innumerable computers can be connected to each other, and they can exchange information among themselves.
In today's modern era, it is such a means that all the people of the country and abroad connect with each other.
Internet facility in India is provided by Bhartiye Sanchar Nigam i.e BSNL (BSNL), but many such companies have also come which can give you internet service in your city itself through your computer. Such companies are called Internet Service Providers. It is also called DNS for short. These companies provide you internet service by charging you a service fee. Like - Jio, Airtel, BSNL, Idea etc.There are many companies that provide internet service.
how internet works:-
Do you know how the internet works? It runs through the optic cable or marine cable laid in the sea and not by any special type of satellite. These three companies run together, the first is the company that reaches the optic fiber cable under the sea to the whole world. Since the Internet is absolutely free, only the money that is spent in the maintenance of this cable and buying the cable is taken only for that money. The speed of this cable is 100-200 gbps.
If we talk about its landing point cable in India is located at places like Mumbai, Chennai, Cochin etc. If you want to see better this laid cable then you can see through this web site https://www.submarinecablemap.com/ That it is spread like a net all over the world.
Second, the company that provides us internet service such as Jio, Airtel, BSNL, Idea etc. Since Reliance Jio has laid its own optical fiber cable i.e. Samarin Cable between Asia and Europe and even it has been laid all over India so it provides us the cheapest internet service.
Jio, Airtel, Idea etc. All of them have their offices in Mumbai or Bangalore or Delhi, which have their own servers. This server is connected to the tower installed in the country and we use it in our mobile or laptop or computer. Since their internet speed is like 100 gbps and if the number of users is more then the speed of the internet also becomes less ie slow and we say that the net is running slow especially this problem happens during the day. But at night, as many users are not running the internet, so it gives very good speed.
