How does the internet work?

The information or video you are looking for on the Internet has come thousands of miles from the Google Data Center to reach the reach of people. The question is, how did the video come from such a distant data center on a mobile or laptop?

How is information or video spreading all over the world, how is the Internet working, and what is the process of ensuring the personal safety of users?

Internet key

First of all, what is the Internet or the Internet? It is basically a network interconnected between countless computers and devices in different parts of the world. The Internet is a combination of many computer and device networks that are widespread, interconnected around the world, with a networking system open to all. Vinton Gray Curf is said to be the father of the Internet. Then its name was 'Arpanet'.

How are all the computers in the world connected via the internet?

A kind of strong cable is used to connect all the computers in the world to each other. The Internet connects the whole world with about 8 million kilometers of optical fiber cable extending under the sea like a net. This fancy communication system was first invented in the United States. A company called Milnet began using the Internet to prevent communication between the United States and the Soviet Union from shutting down after World War II. However, internet usage started in Bangladesh in 1993.

Internet address

Each computer connected to the Internet must have its own address, known as IP. This means Internet Protocol. Each is different for computer connection.

Networking infrastructure

Suppose a sender sends his message to the recipient. What he will do is first write a letter, then write the address to which he will send it in the envelope and go to a post office with the address he will send on the envelope. The post office will then deliver the letter to the recipient at that address through a postman. This is how the internet works. How? What is written in this letter is data. The sender who posted the letter from the post office is his IP or the sender's address. The postmaster delivered the letter from the post office to the recipient's address mentioned in the envelope and this postmaster is the internet and the address to which the letter was received is the IP address or address attached to the sender.

How the internet works

The Internet is a means of exchanging a variety of data and media between a wide range of interconnected devices around the world. The Internet works using packet routing networks, connected via Internet Protocol ( IP ) and Transport Control Protocol ( TCP )। TCP and IP simultaneously ensure that the Internet can be used seamlessly on any device from any center of the world। Data is sent in the form of packets and messages via the Internet। Data sent via the Internet is called a message, which is turned into small parts or packets before being sent। These messages and packets travel from one source to another using IP and TCP। IP is basically some of the rules of some systems that monitor when sending data from one computer to another.

In order for the Internet to work properly, it must be connected to its own global network through any one of its kind or wireless। It then collects various data and information by connecting with the various computers involved in the global network through its own computer routers and servers। This is how the internet works.

Access to the Internet

To use the internet you need to access the internet first. The question is how can I access the internet? Basically it is possible in two ways.

First, through optical cable. I.e. WiFi, modem, dial up etc., which are mainly connected to different countries through submarine cable. About 99 percent of the devices are connected to the Internet.

There is also another way, via satellite. In its process, 1 percent of devices are currently connected to the Internet. 3 devices are required for the Internet to work। A device, where Internet usage will continue.

Internet service provider or IP, from which Internet services can be received. Another web browser or application. Such as Google Chrome, Mozilla, Firefox etc. And this browser connects to all the computer networks in the whole world through internet connection.

Is the internet a blessing or a curse?

At present, the use of the Internet has increased so much in people's lives that many people compare the closure of the Internet to suffocation. Many again consider the right to use it as a human right. The Internet is undoubtedly a blessing for mankind.
