Router Definition

The router is the Spanish translation of the English word router , although surely you have also seen it written on a page written as a router, router or similar. The router is the device responsible for connecting two computers together . Inside it contains the appropriate instructions and protocols to allow sending and receiving information packets between them, so that it reaches its destination and does not get lost, always using the most appropriate route at all times. It may seem complex, but in reality it is very simple. Assume an example in which a router wants to send service provider networking solutionsinformation from one server in Spain to another in Argentina. Try sending it directly, but the shipment fails. Then calculate that the best route is to use an English intermediary server. The router in Spain will send the information to the English router, and it is, knowing that the final destination is the Argentine server, sends it to an American server, which sends it to another in Brazil, who finally sends it to its goal. Each router calculates when the information arrives which is the best way for the information to arrive correctly, and also check the information received to verify that it has arrived correctly. And that at every step.Thus, as its name suggests, it gives you a route (and forgive the repetition) to the information you must follow to send it from one computer to another correctly. For this, it uses, as we have said, certain instructions, commonly called routing protocol , and that are inside. This protocol will vary according to the type of network. In Ethernet, for example, the protocol is the so-called IP , which identifies each computer with its own number, to avoid confusion, but they can vary. There are routers that allow several protocols, but currently most are very specific, as they have been optimized for use with a single protocol.

The router can also work by receiving information from a network to which it is connected and then transferring it to computers in its scope of use. This is the typical operation of, for example, wireless routers . These have been connected to the Internet , and within its coverage, any computer can access the network by connecting directly to the router, who will give an IP address to that device and serve as an intermediary to connect to the Internet. There are also private routers for closed networks (such as companies), which operate at the local network level. These routers that create a home network are commonly connected with the acronym of SOHO (which comes from the English wordsSmall Office-Home Office ), although in large companies and multinationals the internal network can become considerable and require more sophisticated routers.
