The term telephone refers to the telecommunication device specially designed to transmit acoustic signals through electrical signals, with geographical distance being the main issue that is solved and simplified with the invention of this device.. In other words, with the telephone communication between people who are at a distance was made possible, and of course from its creation it became one of the most outstanding communication modalities that were created to solve this issue.
Importance of the phone
Even today, the telephone continues to be a hyper popular medium when it comes to communicating, there are even many who are reluctant to abandon it in pursuit of the new options that new technologies bring.
On the phone we have to thank him for coming to improve the communication issue, he streamlined it, he installed it as the means par excellence to communicate at a distance.
And we must also thank him for the impact he has had in helping us to solve and conclude business with people or companies that are not geographically close. And not to mention the help that he brought so that we can intensify the affective relationships with our loved ones who, due to a situation, had to settle in some part of the world distant from ours.
History and controversy of the invention
Surely, many of you like me grew up believing, because that is how we had been taught in school, that the inventor of the telephone was the British scientist Alexander Graham Bell.
Nevertheless, In 2002 and after a long investigation that proved it, it was learned that Bell was actually the first to patent it, but in reality the invention was due to Antonio Meucci, who due to an economic impossibility could only present a brief description of his invention but not formalize it before the United States Patent Office, a fact that ostracized him and into the background and that Graham Bell knew how to take advantage of ... As they say speaking badly and soon, Meucci lacked the dollars that Bell had left at that time and then he could not be responsible for making the telephone recognized and massive, a fact that Bell did achieve. So who was given all the flowers and laurels went to Bell
Towards the end of the 19th century, the telephone became the main means of communication that people used to communicate with each other over a distance, thanks to the fact that a set of devices and conductive systems transmit sound as an electromagnetic signal at a distance.
Basic operation and technological improvements achieved
Basically, the telephone is made up of two circuits that always work together, the conversation circuit on the one hand, which is what is called the analog part and on the other hand the dialing circuit, which will take care of the dialing and the call. . The dialing circuit formed by the dial, which when it goes back, will activate a switch according to the number of times the digit in question is dialed, while the bell is connected to the line through a hook, which will be activated when going off-hook.
Obviously, from its advent to the present, the different successive improvements that were being printed and introduced to the invention are innumerable and practically infinite in order of course to improve transmission: the carbon microphone, pulse dialing using the dial dial, dialing. by tones, the condenser microphone, the connection of the fixed telephony with a central by means of metallic conductors, the DSL or Broadband techniques, among many others.
And a separate paragraph deserves the appearance of the mobile or cell phone that today makes it easier for us to carry telephony on our feet, wherever we move, from work to home, from home to a friend's, we can continue to be connected by phone with whoever we want to do it.
Meanwhile, and in that fabulous universe opened by technology, many more features were added to the mobile phone to the simplest and most recognized way of talking on the phone. Today, we can choose from a variety of incredible mobile phone designs, we can send and receive images and files through the phone, we can surf the internet, as if we had a mini computer in hand.
