How the Internet works Summary

Browsing the Internet is so common that most of us do not go a day without visiting a web page. However, the network is relatively recent and there are many people who still do not know the basics of how it works. If you are one of them, in this post we briefly explain how the Internet works.The Internet network has two main components:

Hardware: would be the “physical” component of the Internet, and includes all the devices that make up the network of networks: devices that can be divided into three large essential categories:

End points: computers, smartphones and in general any device with which the user can browse the Internet.
Servers: the machines that store the information we search for on the Internet.

How internet service works

Transmission lines: They can be physical, as in the case of cables and optical fibers, or they can be wireless signals from telephone list satellites, cell phones or 4G towers or radios.
Protocols: These are sets of rules that machines follow to complete various tasks. Without a common set of protocols, communication between all the machines that make up the Internet would be completely impossible.

Types of protocols
Two of the most important protocols are Transmission Control Protocol and Internet Protocol . They are usually named together as TCP/IP protocol. At their most basic level, these protocols establish the rules for how information passes over the Internet.

The TCP protocol allows two machines that are communicating to control the status of the transmission. For its part, each device connected to the Internet has an IP address. This is how one machine can find another over the massive network.

The web pages you visit have your IP address

It would be difficult for Internet users to remember it an IP is a series of numbers. That is why each website has a domain name associated with its IP, which is the one used to access it through browsers.

How information travels on the Internet
When you type a web address into your browser, your computer sends an electronic request to your Internet Service Provider. The ISP routes the request to a domain name server that will look for a match for the domain name you typed for example.If it finds a match, it will direct the request to the appropriate server’s IP address.

The request will eventually reach a web server. The server will respond by sending the requested file in a series of packets. Packets are parts of a file that range between 1,000 and 1,500 bytes. Packages have headers and footers that tell computers what is in the package and how the information fits with other packages to create a complete file.

When the packets arrive at your computer, it assembles them to create the page you see on the screen. As you may have seen, the entire process is a matter of microseconds.

This process is valid for any information that Book Your List travels over the Internet, from emails to VoIP calls. Of course, the reality is more complex, but we hope we have given you an idea of ​​the general process.
