The roots of the Internet go back to the late 1960’s. At the time , a project called the ARPANET was funded by the U.S Department of Defense (ARPA was Advanced Research Projects Agency).The goal of the Arpanet was to connect a number of computing facilities aroud the country.
The late 1960’s was during the cold War, and the U.S.Department of Defense was particularly concerned with the possibility nuclear attack. For this reason, the Arpanet was designed to keep working even if someone dropped a bomb on the part of the network. If some of the communications links are destroyed the rest of the network will still function.
The project to create such technology was successful and throughout the 1970’s and the 1980’s the network expanded and became the internet. At first the internet connected only military and university computers, but gradually more and more companies and individuals joined. Today millions of people around the world have access to the internet –what we network call the NET.
Thus in a single generation, the internet grew from an experimental project to global network that has permanently changed our lives. By any standard the NET has been fabulously successful. But why did this happen and how did it happen so quickly ?. The answer is twofold .
First the original technology developed for the U.S. Department of defense has proven to be highly reliable. Although no one has ever dropped a bomb on the NET it is common for computers and communication lines to stop working temporarily. When this happens the computers that run the internet automatically re-route the flow of information around the broken links until they start working again. So one reason the internet has grown so large is that it is so resilient.
The Second reason the NET grew so quickly has something to do with the nature of the human beings, We are a species that loves to communicate. To participate in the Internet you need a computer but it was not until the mid 1990s that personal computers became both powerful and inexpensive. However once the average person could afford the PC, it did not take long for tens for millions of people to buy a computer and join the NET. The history of 20th century shows us that people have always used the new technologies to communicate faster and better. There is something in our biological blueprint that makes us want to talk to one another and to share information
