Let's start by describing briefly what is internet in rather simple terms, then we know some of these personalities.

Right now, a lot of information is displayed and transported to your computer through internet. It consists of two main parts: a software and hardware. One allows the physical connections that facilitate contact (hardware) as cables, servers and more, and the other allows the encoding and decoding of information (software), such as programs, browsers and others.

All this works in a way that is decentralized communication networks interconnected by TCP / IP protocols, enables operation as a logical network that spans the globe, connecting billions of computers globally a huge joint system. To all this we call internet.

}Internet has revolutionized the world. Today is 40 years old and has reached more than 2.4 billion users. since 1969 the first connection between computers at Stanford and UCLA was performed when ARPANET was also born.
