For a simple paradigm, the easiest way to explain this is to use the “Iceberg Model”. Ok - with the history lesson out of the way, we’ll get back to the underlying purpose of this article, which is to reveal the three “layers” of the internet. To make this easier to understand (hopefully), I’ve put together the below diagram Out of this new model came, effectively, three layers of the internet. This method also gave content owners a mechanism to charge users for access to content - referred to today as a “Paywall”. However, over time, the internet model changed as a result of various sites wishing to remain outside of the reach of search engines such as Google, Bing, Yahoo, and the like. The icing on the cake came in 1990 when Tim Berners-Lee created the World Wide Web (www as we affectionately know it) - effectively allowing websites and hyperlinks to work together to form the internet we know and use daily.
In 1983, ARPANET began to leverage the newly available TCP/ IP protocol which enabled scientists and engineers to assemble a “network of networks” that would begin to lay the foundation in terms of the required framework or “web” for the internet as we know it today to operate on. Both TCP and UDP use a principle of “ports” to create connections, and ultimately each connected device requires an internet address (known as an IP address which is unique to each device meaning it can be identified individually amongst millions of other inter connected devices). It’s an enormous collection of networking components such as switches, routers, servers and much more located all over the world - all contacted using common “protocols” (a method of transport which data requires to reach other connected entities) such as TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). The internet itself isn’t one machine or server. Department of Defense, and used early forms of packet switching to allow multiple computers to communicate on a single network - known today as a LAN (Local Area Network). The product was initially funded by the U.S. The first workable version came in the late 1960s and used the acronym above rather than the less friendly “Advanced Research Projects Agency Network”. The “internet” as we know it today in fact began life as a product called ARPANET.
Let’s first understand the origins of the Internet However, how well do we really know the internet and its underlying components ? When you think about the internet, what’s the first thing that comes to mind ? Online shopping ? Gaming ? Gambling sites ? Social media ? Each one of these would certainly fall into the category of what requires internet access to make possible, and it would be almost impossible to imagine a life without the web as we know it today.
