I Internet: Internet is generally defined as the global network of networks. The networks that are part of this network can communicate with each other through a protocol called TCP / IP (Transmission Control Protocol / Internet Protocol). 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. ICQ ( ‘I Seek You ): A program that allows you to find friends and contacts that you’re online.Lets you send messages and files, make chat establish voice and video connections, etc. IEEE: Institute of Electrical and Electronics Engineers, important technical and professional association, based in the United States. Founded in 1884 and in 1998 was approximately 320,000 members in 147 countries. It promotes research in diverse fields such as aerospace, computing, communications and biomedical technology. 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. The infrared technology plays an important role in wireless communications. ISDN: Integrated Services Digital Network: telephone transmission system to digital. With an ISDN line and an ISDN adapter can surf the Web at speeds of 128 Kbps, if the ISP also has ISDN. ISO: International Organization for Standardization. Founded in 1946, is an international federation to unify standards in a hundred countries. One is the standard OSI reference model universal communication protocols. ISP: Internet Service Provider.Input (data entry): This refers to information received or the process of receiving information. Is the information produced by the user with the purpose of controlling a computer program. The user interface determines what kinds of input accepts the program (eg written text, mouse clicks, etc). The entry may also come from networks and storage devices.
