On January 1, 2013 Internet turned 30. It was on this day in 1983 when Internet Protocol was launched which replaced vulnerable Network Control Program (NCP) used previously, thereby making sure the network was not susceptible to a single point of failure. This meant a single attack could not bring it down, making it safer and more reliable.
On this day, it was the first time the US Department of Defence (DoD) commissioned Arpanet network fully switched to use of the Internet protocol suite (IPS) communications system.
Later, British computer scientist Tim Berners-Lee used it to host the system of interlinked hypertext documents he invented in 1989, known as the World Wide Web.
