Internet and how it changed the world

 

🌐 Early Beginnings (1960s–1980s)

The internet’s roots trace back to the Cold War era. The U.S. Department of Defense funded a project called ARPANET (Advanced Research Projects Agency Network) in 1969. Its goal was to create a communication system that could survive disruptions, such as a nuclear attack.

• ARPANET connected a small number of universities and research centers.
• It introduced packet switching, a method of breaking data into pieces and sending them across networks efficiently.
• In the 1970s, scientists like Vint Cerf and Bob Kahn developed TCP/IP, the core communication protocol still used today.

On January 1, 1983, ARPANET officially adopted TCP/IP—often considered the “birth” of the modern internet.

🌍 The World Wide Web (1990s)

The internet became widely accessible thanks to the creation of the World Wide Web in 1989 by Tim Berners-Lee.

• He introduced HTML, URLs, and web browsers.
• The first website went live in 1991.
• By the mid-1990s, browsers like Netscape Navigator made the internet user-friendly.

This era saw the rise of early websites, email, and search engines. Businesses and individuals began going online.
