How the Internet works

For individuals all across the world, the Internet is becoming an increasingly crucial aspect of their daily lives. It is difficult, if not impossible, to picture a world without the Internet today. Even though this is a relatively new technology, it has quickly pervaded every part of our existence. We use the internet not just on our computers and cellphones, but also on our refrigerators and other household equipment. For all these things to work properly you need a reliable internet connection as well. You can only rely on the best internet services providers. Xfinity is one to name. Xfinity bundles offer customers fast and reliable connectivity services so your work, entertainment, or communication never faces any kind of delay.

Internet Basics

The term “internet” is commonly used to refer to becoming online. In reality, the Internet is just a standard computer network. It is easily comparable to your home’s LAN, which is essentially a “little internet.” All of the devices linked to your router, which is connected to the internet, make up your local area network. In this example, the internet refers to a vast network of interconnected computer networks.

These computer networks are all linked together through hardware. High-speed cables running beneath city streets outside your home, enormous cables at the bottom of the oceans, and satellites orbiting the Earth are examples of this infrastructure.

What does It Do?

The Internet’s job is to move digital information, often known as data, from one location to another. All of the information handled by the machines that make up the Internet is treated in the same way. In this way, the Internet is similar to the postal service. Letters are simply transported from one location to the next, regardless of who sent them or what messages they contain. The mail service’s purpose is to move letters from one location to another, not to worry about why people write letters in the first place; the Internet is the same way.

The Internet’s simplicity, like the mail service, allows it to manage a wide range of information, allowing individuals to perform a variety of tasks. It isn’t designed to handle emails, Web pages, audio calls, video calls, chat messages, or anything else; all data is treated equally and forwarded in the same way. People can readily utilize the Internet to run new applications or new things that operate on top of the fundamental computer network because it is designed so simply.

It’s critical to remember that the Internet is a global network of physical links, including copper telephone wires, fiber optic cables, and television cables. Even wireless technologies such as Wi-Fi and 3G/4G have physical cords to connect to the Internet.

How Does The Data Travel?

Packets: Packets of data travel across the internet. A maximum of 1,500 bytes can be carried in each packet. A wrapper containing a header and footer surrounds these packets. The wrapper’s information tells computers what kind of data is in the packet, how it fits together with other data, where the data came from, and where it’s going. When you send someone an e-mail, the message is broken up into packets and sent across the network. The paths of different packets from the same message do not have to be the same. That is one of the factors that contribute to the Internet’s robustness and speed. Packets will be passed from one machine to the next until they arrive at their final destination. The computer receiving the data assembles the packets like a puzzle, recreating the message as they arrive.

This idea underpins all data transmissions via the Internet. It aids network traffic management by allowing packets to pass through an alternate path if one becomes congested. This differs from a standard phone system, which uses a sequence of switches to create a dedicated circuit. All information passed back and forth between dedicated links on the previous analog phone system. The call would be terminated if that connection was lost.

Internet Protocols

Each computer must have a numerical address, according to the Internet Protocol. Messages are transferred between computers using their Internet Protocol (IP) addresses. A message is the transmission of data between IP addresses. Messages are broken down into smaller bits, known as packets, for transmission. The entire communication is split into sections and sent separately, to be reconstructed when it is received. The IP address is then used to transport these packets from the sender’s end to the receiver. A unique, numeric IP address can be assigned to each computer or device. IP addresses are made up of numbers rather than words.

Routers and IP

Computers use a packet routing network to send and receive messages using the Internet Protocol addresses as well as the Transfer Control Protocol. Computers can share data via the internet by sending messages back and forth across a wide, complex network.

The technology responsible for handling this communication is a Packet Routing Network. This is why, in most cases, using the internet involves the usage of a router. A router is hardware that connects multiple computers to build a network. The router is an important piece of equipment that directs packets to their relevant destinations.


This was a simple walk-through of how the internet works behind the scenes. Having a rudimentary grasp of what goes on behind the scenes can demystify some of the magic and help us appreciate the internet, which we’ve grown to rely on for pretty much everything. Although the first router for the internet was set up back in the 1960s only for military purposes today it is a global phenomenon and life cannot be imagined without it.
