Internet|Explain of Internet
People who haven't heard the word internet can't be found. And now we all use the internet more or less. But how many people know about this internet? Although everyone uses the internet, most of them do not know the meaning of the internet. And most people will not be able to answer this question. So today we will learn about this internet.
The Internet is used all over the world in just two ways. One is via fiber submarine cable and the other is via satellite.First of all, we get internet through a huge amount of fiber optic cable lying on the bottom of the sea. And one thing we all need to know is that 99% of the internet we get is through fiber optical cable located at the bottom of this ocean.And the second medium is satellite.
What is Internet?
The Internet is a global computer network. It is a network through which we can share and exchange any video or data with each other. And the network through which we can create a world-class communication system is the Internet.
Simply put, if you connect your two computers together via a cable, it will be an Internet. But in this case you will not have any cost. And it doesn't really cost anything to use the internet. But where is the cost? In fact, the cost is only for the installation of the Internet and the maintenance of the cable that is connected to the seabed.
And the distance of this submarine cable is very big and it is very expensive. As a result, its management is very expensive. So to put it simply, the cost we incur for internet usage is actually the cost of management of that submarine only.
How Internet works?
We already know that the Internet is the name given to connecting multiple computers together. So in this case there are different means to connect one computer with another computer. One of them is only medium and the other is radio medium. Cables include copper cable or optical fiber cable and another is wireless medium. The source of wireless media is satellite based communication medium. Some advanced versions of Wireless include technologies such as Wifi, LiFi & 5G.
But we have already compared the internet to the postal system. Now how does this postman with internet name find your or your friend's address? And the answer is that every device that uses the Internet has its own unique address. This address is called Internet Protocol Bok IP Address. And with the help of this IP Address the sender and the recipient are identified. And one thing to keep in mind is that in the case of data transfer the computer does not understand which is the file, image, video or audio. The computer only knows the code. So in order to transfer any data, the computer first converts it to some specific code. The codes for each image or video are much larger. And transporting so much big data in one way can cause traffic jams on the internet. As a result, communication will be very slow. So to solve this problem, those codes are first broken down and sent to the IP address of the customer in different ways. And the little codes that come with these different roads go to your friend's computer and all of them come together again to form a complete video.
