According to DigoPaul, a connector is something that connects : that is, it allows a connection to be established (a union, a link, a communication). The concept has several meanings depending on the context.
The device that connects different electrical circuits is called a connector. There is a large number of electrical connectors, each with its own characteristics and peculiarities. At a general level, it can be said that most connectors consist of a base (the female part) and a plug (the male part).
There are connectors that establish a temporary connection, while others allow the development of a permanent connection. While some connect easily, there are also connectors that require tools to achieve assembly.
The RCA connector, for example, is a kind of connector that enables connection between a television and a DVD player. It is the typical cable that has a red connector, a white connector and a yellow connector: the first two allow to connect the sound in stereo and the yellow one, the video signal.
The USB connector, for its part, is usually associated with the one used to connect a camera, a cell phone (mobile) and other equipment to a computer (computer), although since the creation of the Universal Serial Bus, in 1996, various connectors have been launched that respond to this communication specification, each with new possible uses.
A few decades later, the USB connection standard continues to be very useful in all technological fields thanks to its great versatility : it not only offers us the possibility of communicating computers and peripherals, one of its basic functions during its first years on the market., but also allows the battery charging of mobile devices (such as phones, tablets and portable consoles) and the transmission of audio and video data in high definition.
In this context, it is important to distinguish between standards (such as USB itself) and connectors. For the same standard, there can be many connectors and, although it is not usually the case, the opposite could also occur (although this would generate great confusion in the market). Broadly speaking, we can list the USB connectors of type A, B, C, mini and micro; There are differences between them both physically and in capacity, such as the form and amount of electricity they are capable of transmitting.
It should be noted that even the plugs whose plugs are inserted into an outlet to allow the passage of electrical current are connectors.
In the field of linguistics, on the other hand, a connector is a unit that relates fragments of a text, sentences or syntactic groups semantically and logically. An example of a linguistic connector is but : “I would like to stay with you but I have to go”, “Those pants are very expensive but I will buy them anyway”.
It is also known as a discursive or textual connector, and its existence is essential for our communication, since it allows us to amalgamate ideas and make messages clearer. It is important not to confuse this concept with that of grammatical nexus, a particle, morpheme or word that has the function of joining two sentences, phrases or words together, in a purely grammatical way.
Among the disjunctive connectors, expressions that serve to separate ideas within a text, we find “either that” and “whether”. The causal, on the other hand, allow to introduce a reason or cause to a given effect; the most used are “for this reason, therefore, then, therefore, that is why” and “since”. Other of the most relevant are locatives, thanks to which we can indicate a reference site: “there, here, above, next to” and “below” are just some exponents.
