Internet comes from "interconneted networks"(" interconnected networks "): basically these are millions of computers connected to each other in a worldwide 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. This format gives rise to one of the paradoxical virtues of the Internet: its state of permanent anarchy, that is, the impossibility of a single central regulation of the sustained flow of information that transits between the different terminal points that comprise it.
The communication protocols employees to make up the Internet belong to the family TCP / IP, these represent forms of "talk"and to 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 of the Earth in the As access to information by the population 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" an important part created in 1990: the set of Web pages (or Web sites) that can be reached from anywhere. The service most used by users around the world is probably e-mail, which has replaced more than 50% of conventional postal mail and which enables outstanding connectivity between people at remote points, as well as the exchange of information in the world. framework for 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. Back then 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 an 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 the resources used for connectivity between equipment, it was possible in the first instance to accelerate the transmission of information (from the use of telephone modems in the beginning to the current wireless and satellite resources) and, secondly, the possibility of achieve 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 through voice over IP (VoIP), television over IP (IPTV), remote access to other computers via Telnet or SSH and NTTP bulletins.
All this infrastructure was gradually passing from the universities, state agencies and large companies to the 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 and 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 adverse comments: the lack of "training" to deal with such a volume of "information", on the one hand , and the copyright implications of numerous patented works, on the other. However, the own Internet seems to slowly improve these deficiencies. Thus, the number of online courses and training modules on the most varied topics is increasing, aimed at training users to make correct use of information. In the same sense, numerous universities and scientific associations include distance 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 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.
