Cable

Meaning of Cable

Cable is a term with various meanings and uses. It may be the cord that has different conductors isolated from each other and protected by some type of sheath.

According to DigoPaul, the electric 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 made up of the conductor (the element formed by one or more wires that conduct electric current), the insulation (which covers the conductor so that the electric current does not circulate outside the cable), the filler layer (an insulating material that allows to preserve the circular shape of the set) and the cover (the materials that protect the cable from the sun, rain, etc.).

The coaxial cable on the other hand, is one that has two concentric conductors and can carry signals electrical high frequency. The conductors are separated by an insulating layer known as the dielectric.

The term cable is also used to refer to 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 entails installation) and pay a monthly fee, unlike so-called open television (whose channels are usually freely accessible through an antenna).

The popularity of cable has declined in recent years, in part due to the increasing amount of entertainment available over the Internet and, unfortunate as it may sound, thanks to piracy. Although more and more countries begin their fight against the exchange of illegal content through the Internet, it is still possible to download movies, series and music without paying a single penny to their creators.

Needless to say, not all free content on the Internet is illegal; on the contrary, thanks to the monetization system that is based on advertising, artists from all over the world can offer their creations without directly asking their followers for money. 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 are sustained 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 for color television and £ 49 for black-and-white transmission, which must be paid for each television owned at home. This tax is required of anyone who wishes to watch live programs, for which those who use the device to play games (connect them to consoles or computers) and to watch program replays, among other well-detailed cases, are exempt.

The provision of the 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 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 doing without the cable entails a certain loss of speed and affects reception, the great comfort that it represents weighs more for most users.

Lastly, the notion of diplomatic cable makes mention of the type of communication issued by an embassy or a consulate to the foreign minister of your country. The word cable refers to the fact that, some time ago, these communications were sent through submarine cables.
