What is the internet? Everything you need to know about the internet

Although many of us don't know how it works, we cannot live without the internet. 5,000 domain names are purchased every hour and 250 million e-mails are sent every day. But even the loading of web pages and e-mails falling into our inbox seems a bit magic to us. The internet system, which looks extremely mysterious, actually works with an extremely easy to understand mechanism.

Internet essentially means 'inter-network communication' and defines the possibility that all telecommunication networks give an individual to communicate with another individual.

In other words, the internet is 'networks of networks'. In other words, it provides information transport between networks. The term information highway can also be used to describe the internet. Because of these definitions, many people see the interior as a concept or abstraction. In fact, this belief is more or less correct. Professor Milton Mueller, who runs the intergovernance.org site, described the Internet as 'more a process than an object' in an article he wrote for Time magazine in 2014.

But engineer Tony Li, the creator of the routing protocols that provide the internet, says that the current state of the internet consists of physical and metaphysical components. To a question asked on the question and answer site Quora, Li said, “Yes, the internet exists physically. The internet is a team; It is a combination of many different components. Yes, these components are individually owned and operated with their respective autonomous systems. But the fact that they are committed to creating the internet in terms of function is indisputable. '' Li also suggested 'leaving the master router' at the feet of those who doubt their physical existence, giving examples such as data centers, fiber, coaxial cables and routers.

There are cables even in the oceans, and these cables are extremely surprising. Installation of submarine communication cables is carried out by special ships. The thickness of these cables is the width of a soda bottle and a felt tip pen. Cables are thousands of kilometers long and can be expressed in material value in millions of dollars. International disruptions on the Internet are caused by the ships cutting these cables.

The most important point you need to realize in the information mentioned here is that the internet is not in the sky or in the clouds, but here on Earth, and is visible.

How does the internet work?

Although many people connect to the internet wirelessly, internet connections necessarily need a cable. Even if you are connected to the internet with wireless internet (Wi-Fi), the connection will necessarily revert to a router. Routers connect to cable networks. In smartphones, the wireless connection is connected to a base station connected to the cable network by cable. Whether it is fiber optic or copper, cables tied under the floor or to electric poles are connected by a network of Internet cables.

There are servers and clients in the internet world. Servers are machines that provide services to other devices and are directly connected to the internet. There is an email server, web server, and data server, and each server has a static internet protocol IP address that never changes. IP addresses allow computers to find each other.

The laptops you use in your home are not a server but a client. Because home computers are directly connected to the internet by the internet service provider (ISP). To connect to the internet from your home, you connect to the Wi-Fi connection provided by the internet service provider. The internet service provided by the internet service provider connects you to the server's IP address. Web pages and e-mails are files located on the server's hard drive.

How does information sent over the Internet know where to go?

Every time you send an image, file or message over the Internet, the computer divides the information into smaller sections. This is called a packet (data). Packages revert to their original state as soon as they are received by the server.

To make sure the information reaches the correct destination, servers send files to an IP address. Your IP address as a client depends on your location and how you connect to the internet. IP addresses are also used by internet service providers to detect illegal criminal activities.

What is a router?

The router intersects two or more devices anywhere to connect with the internet service provider. Routers take the task of helping packages reach their destination on the Internet. It allows you to take 10 to 15 routers packages from your computer every time you visit a website anywhere.

How computers connect to wireless internet (Wi-Fi)?

Wireless internet works just like Bluetooht technology. It uses radio frequencies to transmit signals between devices. A computer with wireless internet capability connects to the internet with the signals it receives from the wireless router over the Gigahertz range. The word Wi-Fi stands for wireless internet connection, Wireless Fidelity, and it means wireless connection and is synonymous with wireless local area network WLAN (wireless local area network).

Who owns the internet?

The answer is simple; No one! Basically, everyone pays in one way or another to benefit from internet service. There is no person or institution that owns the Internet. When you buy a domain name, you actually pay for part of the internet infrastructure.
