yH5BAEAAAAALAAAAAABAAEAAAIBRAA7 - Internet: - Browsers - How Internet Works

How it really works:

We already have clear the fundamental parts that participate of the process we begin to explain how it works.

Internet is governed by protocols, are ways to encode and decode information, for example browsers can read programming languages ​​like HTML, Java, Flash, PHP, and many more. Then, any site that works with compatible protocols can be read by a normal computer. They are called transmission control protocol (TCP).

Another information to take into account are the IP addresses, you may have already heard about them. These are the addresses assigned to each of the Internet terminals, by which we mean that each computer, each smartphone and each server has its own IP, unique and unrepeatable.

This way it is so easy to track a computer to send information and also receive it.

With this we want to explain that the Internet is not a heap of information in a super bag, it is a network of computers interconnected among them around the world. Millions and millions of computers sharing your second-to-second information

When we click:

Now, each time we click on a notice, or enter an address to enter a site, our browser encodes that order so that it enters a packet of information (which would be unreadable to us).

This packet of information is sent via the internet cable to our internet service provider (ISP). This internet provider in turn transmits this packet to the domain name server (DNS).

For example if you want to enter to, Your provider will send the information to the DNS, which will look for the server where the site is hosted and send the package to it.

The server is like another great computer, this counts with its physical part (its hardware) and its virtual part (its software). The server has a physical sector where it has stored the information of the site, and a virtual sector which serves to decode the package that was sent.

Once the packet is decoded, the requested information is sent, again in a packet encoded by the DNS to the Internet Service Provider (ISP). This in turn sends it to your computer and your browser decodes this same package in order to show you LuisiBlog as you see it.

The Internet is a large chain that encodes and decodes code at high speed. In a matter of seconds our information travels to its destination in another part of the world bringing new information in turn.
