Concept in Definition ABC

Internet comes from "interconneted networks"(" interconnected networks "): basically these are millions of computers connected to each other in a global network.

Its form of operation is decentralized, this means that the information does not necessarily need to pass through a network node, but can take alternative paths as required. East Format gives rise to one of the paradoxical virtues of the Internet: its state of permanent anarchy, that is, the impossibility of a central and sole regulation of the sustained flow of information that transits between the different terminal points that make up.

The communication protocols employees to shape the Internet belong to the familyTCP / IP, these represent forms of "speak"and be understood between different computers and other types of electronic devices. Through unified communication protocols, the logic is homogeneous, so that it is relatively easy to provide an international scope. However, in some nations on Earth in which access to information by the

population It is limited, mechanisms have been put in place that allow governments to prevent the arrival or departure of certain digital content. The paradigmatic example is China, despite the very high number of Internet users in the Asian giant.

The Internet provides several services, among which are the chat via IRC wave world Wide Web, but the latter has been so successful that it is often confused with the network itself, and in truth it is "only" one important part created in 1990: the set of Web pages (or Web sites) that are reached from any point. Probably the service most used by users around the world is the email, which has replaced more than 50% of the conventional postal mail and which allows an outstanding connectivity between people in remote points, as well as the exchange of information within the framework of the dissemination of attachments of all kinds.

The origin of "the network of networks"goes back to year 1969, at which time it was possible to connect university establishments between Utah and California, in the United States of North America. At that time the network was called ARPANET, a name that was largely linked to the idea that the northern country needed to defend against nuclear attacks, and therefore form a communication network that could not be dismantled with the destruction of one of its points.

If the network were serial, with destroying any point in the middle, the communication would be cut off, instead the form, decentralized through ARPANET nodes, really provided a infrastructure capable of withstanding nuclear attacks. It happens that, according to specialists, this was not the only reason for its creation. With the optimization of resources used for connectivity between equipment, it was possible in the first instance to accelerate the transmission of information (from the use of modems telephone lines at first up to the current wireless and satellite resources) and, secondly, the possibility of achieving connection to Internet from non-conventional equipment (cell phones, laptops, video game consoles, smart TVs).

Other Internet services They are: the transmission of files via P2P or FTP, the sending of mail via SMPT, communication by means of voice over IP (VoIP), television over IP (IPTV), remote access to other computers via Telnet or SSH and newsletters NTTP.

All this infrastructure was gradually passing from the universities, organisms state and large companies towards popularization that is lived today, becoming established as an article of mass consumption, "engulfing" other media such as radio, TV, cinema, newspapers, magazines or encyclopedias. Internet is, in a way, the great tower of Babel of the XXI century, with billions of people accessing and modifying its content in blogs Y wikis, establishing daily conversations through chat, watching and uploading videos, music and other materials to share with peers. This shocking dissemination of information has motivated a great positive change in terms of the dissemination of knowledge, but has warned the experts two comments adverse: the lack of "training" to deal with such a volume of "information", on the one hand, and the repercussions on the copyright of many patented works, on the one hand, the other. However, the own Internet seems to slowly improve these deficiencies. Thus, the number of online courses and training modules is increasing. training on the most varied topics, aimed at training users to make correct use of information. In the same vein, numerous universities and scientific associations include remote content for their students and for those who choose to train in this new way. On the other hand, the authors and artists themselves have warned of the importance of Internet for the dissemination of their works and they have begun to warn that micropayment systems and other related resources allow them to obtain a fair return for their creations, without preventing their digital dissemination and at the same time allowing them to act independently of publishers and record companies.

A) Yes, Internet constitutes a revolutionary change in communication between human beings in constant change, growth and novelty.
