Key 6 Steps in the Work of the Internet
If you only know about the Internet that there is a lot of information and you can find/watch/buy anything, then this article will probably come in handy for you.
As a result, you will learn something about the Internet, how it works and how it gets to your screen.
Step 1
You have a device – a desktop, laptop, tablet, smartphone, or something else like that. At first, it is autonomous, i.e. you cannot access the world wide web from it. To do this – you need to establish a connection through an Internet provider. They can give you access via satellite, cable, and even a phone line (sounds crazy, but someone still offers this type of connection). By the way, if you are connected to a neighbor’s Wi-Fi, the neighbor is not considered an Internet provider. Although, if you call him that, there is a chance that he will be pleased. And then it will set the password.
When your computer has Internet access, you can finally surf.
The Internet, the World Wide Web, or simply the Network, are computer networks connected to each other, the Internet network throughout the world, designed to store and transmit data.
The Internet is based on the World Wide Web (World Wide Web, commonly known as WWW) and other information transmission systems. According to the latest data, there are 3.4 billion registered Internet users in the world.
Step 2
To go to any site you use a browser. There are many browsers at the moment, but in Ukraine 4 top browsers are used on 94% of computers and tablets: Chrome, Firefox, Opera, and Internet Explorer.
Step 3
So, if you are the owner of OS Windows, you will most likely want to download some other browser via Internet Explorer or Edge. To do this, you need to enter the domain name (i.e. address) of the desired site into the address bar.
Step 4
Now, if you want to get to some site, you need the help of DNS servers.
DNS – Domain name system – domain name system. A DNS server is like a telephone directory – you ask it for a domain name, and in return, it tells your computer what IP address the requested page is located on. This makes web surfing much more convenient because it is easier for us to remember some alphabetic address than a sequence of numbers, say, 78.46.145.62
IP address, IP address – Internet Protocol Address, Internet protocol address – a unique network address of a node in a computer network.
Each device on the network has its own unique IP address. It consists of four groups of decimal numbers from 0 to 255, separated by dots. For example, 175.0.217.21.
Step 5
The DNS server returned a unique number to your computer, and now the browser can connect to the server where the site you are looking for is located.
Step 6
When the web server receives a request from your browser, it displays the page you requested. So many letters, but it happens in the blink of an eye.
A few more words about domains
A domain name is used to identify and address Internet sites and web resources located on them in a digestible form. There are currently over 250 million registered domains, and if you want to create a website with a nice, short name, chances are it’s already taken. It sounds sad, but if you imagine for a second what it will be like for our descendants, then it’s more fun, right?
A fully qualified domain name consists of the domain name itself and then the names of all the domains it belongs to, separated by dots.
For example, “mail.google.com” refers to the third-level domain “mail”, which is part of the second-level domain “google”, which is part of the top-level domain “com”, which in turn is part of the unnamed root domain “.”. Here is such a domain that Jack built)
TLD – top-level domain, top (first) level domain, the highest level after the root
Root domain – the root domain, the highest level domain. This domain is served by root DNS servers, which are located in different parts of the world. It is displayed as a dot at the end of the address, although the dot is often omitted when entering.
There are many top-level domains, but the purpose of most of them is easy to understand from the name.
The bottom line
Now you know how the Internet works. It would seem that everyone uses it every day, but only a few know how it works.
