The Internet
The Internet is a global network of interconnected computer networks that has fundamentally transformed communication, commerce, and access to information since its emergence in the late 20th century.
The Internet's origins trace back to ARPANET, a project funded by the U.S. Department of Defense in 1969, which connected a handful of university and research computers using a new method called packet switching.
The development of standardized protocols, particularly TCP/IP in the 1980s, allowed different computer networks to connect and communicate, gradually forming the global network known today.
The Internet's growth accelerated dramatically after Tim Berners-Lee's invention of the World Wide Web in 1989, which made the network accessible and useful to the general public, transforming nearly every aspect of modern life.
