What is Internet?

7 mins read

Imagine you’re in a large city filled with buildings, each representing a computer. Now, imagine there are roads connecting all these buildings, allowing people, who represent information, to move freely between them. That, in simple terms, is what the internet is: a vast network of computers from all around the world, connected by virtual roads that allow information to travel.

The internet has transformed the way we live. It’s like a giant, worldwide library that holds a massive amount of information and is always open. Whether you want to read the latest news, watch a movie, send an email, shop for clothes, or learn a new skill, the internet makes it possible.

How does this work? When you type a website address into your browser, the internet, like a speedy postman, fetches the webpage you asked for and delivers it to your computer screen. It does this by breaking down the information into tiny pieces, called ‘packets’, sending them through the network to your computer, and then reassembling them for you to see.

The internet started as a way for scientists to share data and has grown into a global infrastructure that influences nearly every aspect of our lives. From small beginnings, it’s become the world’s most extensive platform for sharing information and connecting people. The internet doesn’t belong to anyone in particular, and every computer that connects to it helps make it what it is.

It’s like a global jigsaw puzzle that keeps growing as we add more and more pieces to it, making the world a smaller place, one click at a time.

History of Internet

  1. In the beginning, there was ARPANET (1960s-70s): It all started with a project by the U.S. Department of Defense. They created a network called ARPANET (Advanced Research Projects Agency Network) to allow different computers to communicate with each other. Imagine it as a tiny town where a few houses were connected by small roads.
  2. Enter the World Wide Web (1980s-90s): A scientist named Tim Berners-Lee came up with a brilliant idea while working at CERN, a research center in Switzerland. He invented the World Wide Web, an easy way to access documents and information on the internet. It’s like the town grew into a bustling city, with more houses (computers) and a new set of roads (links or URLs) connecting them all.
  3. Dot-com Boom and Bust (1990s-2000): The World Wide Web opened up opportunities for businesses to sell products and services online. This was the start of the dot-com boom. Companies built flashy digital storefronts (websites), and people were buying into the excitement. But eventually, this bubble burst because many of these businesses were not making enough money to justify their high costs. It’s like a city facing economic downturn after a period of rapid growth.
  4. Web 2.0 and the Rise of Social Media (2000s): The next phase saw the internet becoming more interactive. Now, it wasn’t just about reading information, but also about sharing and collaborating. This era also marked the rise of social media platforms like Facebook, YouTube, and Twitter. Imagine the city turning into a lively place where everyone is not just a visitor but also a contributor.
  5. Mobile Internet and the Internet of Things (2010s): With the rise of smartphones and mobile apps, the internet became portable. Now, you could carry the entire city in your pocket, accessible anytime, anywhere. And it wasn’t just about people anymore; devices started to communicate with each other over the internet, giving birth to the Internet of Things.
  6. The Present and Future (2020s and beyond): Today, the internet is an integral part of our lives. It’s like an ever-growing mega-city where billions of people live, work, and play. And the future? Well, with advancements in technologies like 5G, AI, and quantum computing, the possibilities are boundless. The city is set to grow even larger, become smarter, and more connected.

Who Controls The Internet?

The internet, in its global expanse, is not regulated by any single entity. It’s a bit like a vast city with neighborhoods governed by different sets of rules, but without a single mayor or city council overseeing everything. However, there are organizations that play key roles in its operation, maintenance, and standardization.

  1. Internet Service Providers (ISPs): These are the companies that provide you with access to the internet. They’re like the gatekeepers, controlling the speed and quality of your internet connection. They are usually regulated by national telecommunications authorities, which can enforce rules about things like pricing, competition, and net neutrality (the principle that all internet traffic should be treated equally).
  2. Internet Corporation for Assigned Names and Numbers (ICANN): ICANN is a non-profit organization that oversees the allocation of IP addresses and domain names, making sure that every device and website has a unique identifier. This is essential for the smooth functioning of the internet, ensuring that when you type a web address, you reach the correct destination.
  3. World Wide Web Consortium (W3C): This is an international community that develops open standards to ensure the long-term growth of the web. They set the guidelines and standards for how websites and web technologies should work to make the internet accessible and useful to everyone.
  4. Internet Engineering Task Force (IETF): The IETF develops and promotes voluntary internet standards, particularly the standards that comprise the internet protocol suite (TCP/IP). It’s a bit like a group of architects and engineers who design and update the blueprints for the city.
  5. National Governments: Governments around the world exert control over certain aspects of the internet within their jurisdictions, setting rules about things like content, data protection, and cybercrime. Some governments impose significant restrictions and censorship, while others promote a more open and free internet.
  6. Global Internet Governance: On an international level, there’s an ongoing discussion about how the internet should be governed. Various stakeholders, including governments, businesses, civil society groups, and technical experts, participate in forums like the Internet Governance Forum (IGF) and the International Telecommunication Union (ITU) to shape global internet policies.

Every computer on the Internet is identified by a unique IP address, comprised of four numbers, each ranging from 0 to 255. To make the system more user-friendly, Domain Names were introduced as human-readable alternatives to IP addresses. For instance, an IP address for www.google.com is, a combination not so easy to remember!

Reasons For The Growth of Internet

The astronomical growth of the internet over the past few decades can be attributed to several significant factors:
