The Internet, which has become an essential part of today’s living and working environment, has completed 40 years of its existence.
Pioneered by Len Kleinrock and his team at UCLA, Internet’s beginnings occurred on September 2, 1969 at the ARPANet. The concept and practice grew with extensive research and paved the way for social networking and spurred the growth of YouTube, Facebook and the World Wide Web and other such facilities.
The Internet did not become a household word until the 1990s, though, after a British physicist, Tim Berners-Lee, invented the Web, a subset of the Internet that makes it easier to link resources across disparate locations
Though there is a lot of room for innovation today, artificial barriers threaten to constrict its growth. Spam and hacking attacks force network operators to erect security firewalls. Authoritarian regimes block access to many sites and services within their borders. And commercial considerations spur policies that can thwart rivals, particularly on mobile devices like the iPhone.
