The origins of Internet dating from the early 60s of XX century, where the first theoretical studies launched the idea of connecting computers by sending blocks of digital information (binary code), resulting the first network interconnected in history when the first computational link between the University of Stanford University and Ucla was created.
In the late 60s and early 70s the United States Department of Defense developed the first large global network of communication between computers known as Arpanet, Arpanet was the origin of Internet and worked under the first communication protocols that were developed specifically, these protocols were based for the development of modern TCP / IP used in the current network.
In the late 80s and early 90s were developed the necessary tools (hardware and software) as HTML code, servers to host websites, web browsers ... that technology allowed to the general public access and manage Internet with a simple mouse click, thanks to these and other tools thousands of new enterprises have been creating a new business model based on the net, Google, Facebook, Yahoo, eBay, Wikipedia .... are among other corporations and foundations whose origin and sense are based on Internet.

To avoid these problems are currently being developed laws and global actions to minimize and / or eliminate the harmful effects of the disadvantages mentioned above.
