It was conceived in the late 1960s by the Department of Defense of the United States, more precisely, by ARPA. It was called ARPANET and was first designed to perform functions of research. Its use became popular after the creation of the WWW. Today is a public space used by millions of people around the world as a communication tool and information. Intranet: Intranets are corporate networks that use Internet protocols and tools. Its appearance is similar to Internet pages. If this network is in turn connected to the Internet, it is generally protected by firewalls.

Promotes standardization of rules. Inkjet printer: printer works by spraying ink on paper. Dot matrix printer, or matrix: printer that works by a head, pressing an ink ribbon against the paper. Laser printer: fast printer, high resolution using laser technology. When the beam touches the paper, is an electrostatic image which attracts the ink dry. Printer: peripheral that reproduces text and images on paper. The main types are: dot matrix, inkjet and laser.Artificial Intelligence: simulation of human intelligence processes by means of computer systems. Interface: transition element or connection that facilitates the exchange of data. The keyboard, for example, is an interface between the user and the computer. IP: Internet Protocol. IrDA (Infrared Data Association): Organization founded to create international standards for hardware and software used in communication links, infrared.
