Who invented internet, how it connected globally

post-title

The internet wasn’t invented by a single person—it was developed over time by multiple scientists and organizations.

  • The foundation began with Vint Cerf and Robert E. Kahn, who created the TCP/IP protocol, the core communication system of the internet.
  • Earlier, the concept of networking computers came from projects like ARPANET, funded by the DARPA in the late 1960s.
  • Later, Tim Berners-Lee invented the World Wide Web (WWW) in 1989, which made the internet user-friendly and accessible to the public.

The global connection of the internet happened in stages:

1. Early Network (1960s–1970s)

  • Computers were first connected in limited networks like ARPANET.
  • These networks allowed researchers to share data over long distances.

2. Development of TCP/IP (1970s–1980s)

  • TCP/IP became the standard communication protocol.
  • It allowed different networks to connect and communicate—forming a “network of networks.”

3. Expansion Worldwide (1980s–1990s)

  • Universities, governments, and companies worldwide started connecting.
  • Fiber-optic cables and satellite communication enabled long-distance connections.

4. Birth of the World Wide Web (1990s)

  • Tim Berners-Lee introduced websites, browsers, and hyperlinks.
  • This made the internet easy for ordinary people to use.

5. Modern Global Internet

  • Today, the internet connects billions of devices through:
    • Undersea fiber-optic cables 
    • Satellites 
    • Wireless networks (Wi-Fi, mobile data)
