Have you ever wondered how the internet is built? How data travels across the globe using the internet?
In this article, we will discuss the physical infrastructure of the internet, which makes it possible for data to travel worldwide.
- Submarine Cables:Submarine cables are fiber optic cables that travel under seas and oceans. Countries and continents connect to each other via submarine cables, allowing global internet connectivity. These cables often span multiple continents, with several countries connected by the same cable. Ownership is typically shared by investors from multiple countries.
- Landing Stations:When a submarine cable reaches a country’s shore, landing stations connect the cables to the country’s network infrastructure.
- National Fiber Network:This is the internet backbone within a country, managed by both government-owned and private companies.
- Underground Fiber Optic Cables:Underground fiber optic cables travel within a country, distributing internet connectivity nationwide.
- ISP (Internet Service Provider):ISPs are organizations that provide internet as broadband or mobile data to users. They may connect to the National Fiber Network or Internet Exchange Points (IXPs) to enable users to access the internet. ISPs make it easier to distribute internet to users in cities and rural areas.
- Wi-Fi and Network Towers:Finally, users can access the internet by connecting through Wi-Fi or network towers.
There are also satellite internet providers, who enable internet connectivity through satellites, ground stations, and satellite dish antennas.
