What Is the Internet and How Does It Actually Work?
A simple, easy-to-read guide that explains what the internet is and how it actually works behind the scenes.
The internet is a massive, physical global network of connected computers, servers, cables, and routers that share data using standardized rules called protocols. It works by breaking information down into tiny chunks called packets, sending them through a web of physical wires and airwaves using unique IP addresses, and reassembling them at their destination.
Everyone uses the internet daily. From sending emails to streaming videos, from purchasing things on the internet to doing homework, reading books, working, communicating with friends and relatives in other countries, the list goes on and on. But the vast majority of people do not think of asking the most basic questions, such as what exactly the internet is and how it operates. We all just open the application or the website we need and, in a matter of seconds, get our results, without any thoughts about what the path of the requested information was. The truth is, the internet is one of the greatest inventions humans have ever made. It connects millions of devices and sends tremendous amounts of information each second using principles that are quite simple. In this article, we will give a clear explanation of what exactly the internet is and how it has evolved and what really happens when you send a letter or stream a video online.
What Is the Internet?
The easiest way to explain what the internet is would be to describe it as a gigantic network that consists of a number of smaller networks connected together. The term "internet" actually stands for "interconnected networks." The internet is not a single huge computer that exists somewhere on Earth but millions of devices, such as computers, servers, routers, cables, and even satellites, which operate according to certain common protocols.
Consider the internet in much the same way as the postal service that is used globally. Just as a letter may originate in one country and transit through numerous post offices before getting to the destination address, the information that is transmitted through the internet will go through a number of different places before arriving at the user's cell phone or computer. The postal service does not really mind what is in a letter and all that it does is transport the letter from point to point. The internet does something very similar. It is indifferent to whether the information is in text form, a picture, a video, or even a transaction.
Also useful to remember is the fact that the internet and "the web" are two different things despite the fact that the terms are frequently used to refer to the same thing. The internet is the actual infrastructure and technology, which includes the cables and the connections between the devices. The web is just one of the many services, which is provided by the internet and consists of the websites and web pages accessed through a browser. Video calls, email, and online gaming are other services provided on the same internet.
A Short History of How the Internet Began
However, the internet did not suddenly emerge out of nowhere. The process of its development started several years ago with the emergence of a limited connection between several computers used mainly for scientific and military research purposes. At that time, very limited connections were made, and the notion of an average person being able to use the internet from their own home seemed to be completely unrealistic. With the development of technologies, the limited and closed system gradually evolved into something else.
Today, the internet links millions of people together and an enormous number of websites, and is expanding daily because of more and more people connecting to it each day. This idea that once began as just a small test with just a few computers has turned into the biggest network constructed by mankind and plays an important role in many aspects of our lives today.
