There are cables that allow electricity to be conducted.
Cable is a term with several meanings and uses. It may be the cord that has different conductors isolated from each other and protected by some type of casing .
The electrical cable is one whose purpose is to conduct electricity . It is usually made of copper (due to its level of conductivity) or aluminum (which is cheaper than copper).
These cables are composed of the conductor (the element formed by one or more wires that conduct the electric current), the insulation (which covers the conductor so that the electric current does not circulate outside the cable), the filling layer (an insulating material which allows the circular shape of the assembly to be preserved) and the cover (the materials that protect the cable from the sun , rain, etc.).
coaxial cable
Coaxial cable , on the other hand, is one that has two concentric conductors and can transport high-frequency electrical signals . The conductors are separated by an insulating layer known as a dielectric.
The term cable is also used to name cable television , a service that allows consumers to access television signals through coaxial or fiber optic cables. To contract it, you must request registration (which involves installation) and pay a monthly fee, unlike so-called open television (whose channels are usually accessible for free through an antenna).
An Internet connection can be established through fiber optic cables.
Illegal content
Cable's popularity has declined in recent years, in part due to the increasing amount of entertainment available over the Internet and, unfortunately as it may seem, thanks to piracy. Although more and more countries are beginning their fight against the exchange of illegal content over the Internet, it is still possible to download movies, series and music without paying a single cent to their creators.
Needless to say, not all free content on the Internet is illegal; On the contrary, thanks to the monetization system based on advertising, artists from all over the world can offer their creations without asking their followers for money directly. Just as open television does not usually require users to pay a subscription, countless singers, actors and teachers (among many other professionals) share their art and teachings with the world, and sustain themselves thanks to the advertisements that accompany their presentations.
It is worth mentioning that in England you do have to pay to access open television (also called public); This is a fee of 145 pounds for color television, and 49 for black and white transmission, which must be paid for each television owned in a home. This tax is required from anyone who wants to watch live programs, which is why those who use the device to play games (connect them to consoles or computers) and to watch program replays are exempt, among other well-detailed cases.
cable internet
The provision of Internet can be done through different means: the main ones are 3G, 4G, fiber optics and ADSL, some of them with their variations. The last two require a wired connection that goes from a central office to the address where the service is contracted.
Once there, it is possible to use a wireless router to avoid the physical connection of the devices that will connect to the Internet. Although going without the cable entails a certain loss of speed and affects reception, the great convenience it represents outweighs for most users.
A diplomatic communication
The notion of diplomatic cable , finally, refers to the type of communication issued by an embassy or a consulate to the chancellor of its country.
The word cable refers to the fact that, once upon a time, these communications were sent through submarine cables.
