A hub is a device that makes it possible to concentrate and expand the wiring of a network.
The concept of hub is not part of the dictionary of the Royal Spanish Academy ( RAE ). The term, however, is frequently used in different contexts.
In the field of computing , a device that is used to concentrate the wiring of a network and expand it is called a hub or concentrator . The hub can work at the media access layer in a TCP/IP model or at the first layer (the physical layer) of an open systems interconnection ( OSI ) model.
How a hub works
Upon receiving an incoming packet, the hub transmits it to a different port. Since you can use any other port beyond the input port, collisions can occur that affect the flow of data traffic. Generally, these devices are able to detect when excessive collisions occur.
Currently hubs are not widely used, since switches are preferred. In this case, the switch manages to connect different sections of the network to merge them into the same network .
An airport that functions as a connection or distribution center is called a hub.
The term in the transport sector
In the field of transportation , on the other hand, a hub is a distribution center or transit connection for goods or people. In aviation, for example, a hub is an airport that an airline uses as a reference point .
In these types of hubs, various air connections can be made to reach multiple destinations. That is why many flights stop at the hub, allowing the exchange of planes according to the passenger's needs.
Hub linked to TV and communications
A satellite hub , likewise, is a station that is used to retransmit data, voice and television services. These are nodes that connect satellites with terrestrial communications networks.
In the same way, we cannot ignore that the word in question is used to give the title to a channel. Specifically, the television channel responds to the name of The Hub, which is of American origin and which began broadcasting in 2010 and was finally replaced by Discovery Family in 2014.
The content of the aforementioned channel was aimed at children between the ages of 6 and 12, which is why it broadcast programs and series for children of those ages such as “My Little Pony: Friendship is Magic”, “Adventure Camp”. or “The Wonders Years.”
Other uses of the notion
Likewise, it should be mentioned that there are different populations throughout the world that also use the term we are addressing. A good example of this is Hub, from the province of Balochistan (Pakistan). It is a city that has almost 65,000 inhabitants and is located 24 meters above sea level.
In the same way, in California there is also another city that responds to that name.
Finally, we have to indicate that the term in question in capital letters, HUB, are the initials by which the Belltvige University Hospital is also known, which is located in the Barcelona town of Hospitalet de Llobregat and is publicly owned. . Its construction began in the 1970s and it provides all medical specialties except pediatrics and obstetrics.
