In march 1946, a short story was published in the \textit{Astounding Science Fiction} magazine, the author, Murray Leinster, whose real

name was actually Will F. Jenkins, tells the story of Joe, a ``Logic'', which resembles a modern computer. During the plot, Joe develop

some kind of conscience and ambition, and being connected with other Logics around the world, Joe proceeds to cause all sort of events

which make this piece of literature an excellent reading material. Back in the day, this reality was set in the science fiction scenary,

but in the later 1950's a network of computers begin to take shape in several Computer Science labs in the United States, France and

United Kingdom. Initially it was meant to be used as a tool to exchange scientific knowledge, although, in the 1960's the US

department of defense sees the military potential of this newborn technology and starts to fund the research, given origin to the ARPANET,

the first computer network to uses the Internet Protocol (which everyone knows today as the IP address), a message sent from the computer

science lab of Professor Leonard Kleinrock, at University of California, to a computer located in the Stanford Research Institute set the

milestone for the development of the modern day internet. From then the network only grown, in our days there is more interconnected computers

and information being exchanged than the first pioneers could ever imagine.\\

Before the internet, communication between long distances could be tricky, telephone did not always work, and to exchange bigger

amounts of information one would have to rely on printed paper. Information, this vague concept rules the modern world
