Evolution of the Internet

A Brief History

The internet, a fundamental part of modern life, has a rich and fascinating history that spans over five decades. From its humble beginnings as a military communication network to its current status as a global, ubiquitous entity, the internet has revolutionized the way we communicate, access information, and conduct our daily lives.

Early Years (1960s-1980s)

The internet's precursor, ARPANET, was born in 1969 as a project of the United States Department of Defense's Advanced Research Projects Agency (ARPA). Developed by Vint Cerf and Bob Kahn, ARPANET aimed to create a network that would facilitate communication between government and academic researchers.

In the 1980s, the Internet Protocol (IP) was developed, allowing different networks to communicate with each other. This marked the beginning of the modern internet.

The World Wide Web (1990s)

In 1989, Tim Berners-Lee invented the World Wide Web (WWW), making it easy for users to access and share information using web browsers and hyperlinks. The first website was launched in 1991.
