created by: Alexander S. da Silva
Telecom is a way to extend the reach of normal communications. "Tele" in Greek means "air" and derives from the Latin word communication "Communicare" which means making common share, to confer.
When the destination of the information is close to the source, transmission is direct and immediate, as processes conversation between two people in the same environment.
When the distance between them increases, however, the process of direct communication becomes more difficult.
Then there is the need for a system telecommunications, a set of tools and devices allowing the source and destination to communicate at a distance.
Communication is the process by which a generated information at one point in space and time called source is transferred to another point in space and time called destination.
Telecommunications is the transmission, emission or reception, by wire, radio broadcasting, optical or any other electromagnetic process,
symbols, characters, symbols, writings, images, sounds or intelligence of any nature.
Telecommunications networks are being improved to support the transmission of information with the introduction of new technologies,
affecting both the network equipment, as the means transmission and operation systems for management.
A telecommunications network can be composed of several sub-networks, depending on the type of service is provided to the consumer.
Services used by subscribers are willing into categories. The most common categories are:
Dedicated access is a technical term related to central telephone service or connection type between a computer or terminal to the Internet.
It is the connection between a phone or phone system, as an Automatic Call Distributor
or a company PABX and long-distance carrier or telecommunications services.
The connection is via a line dedicated to connecting the two systems.
The line has all its layers automatically routed to a specific line that leads to the PBX or equipment similar exists in the operating company,
so that calls between offices located in different locations can only be done with the dial a telephone extension, like internal links.
Communication is a field of academic knowledge studying the processes of human communication.
Among the subdisciplines of communication, include information theory, communication intrapersonal, interpersonal communication,
marketing, publicity, advertising, public relations, discourse analysis, journalism and telecommunications.
It also considers communication as the exchange information between subjects or objects.
From this point of view, the communication includes technical issues, biological and social.
Human communication is a process that involves information exchange, and uses the systems as symbolic support for this purpose.
Are involved in this process a multitude of ways to communicate:
two people having a conversation face to face, or through gestures with his hands, sent messages using the global telecommunications network,
speech, writing that allow you to interact with other people and make some sort of informational exchange.
In the process of communication that is involved in some kind of apparatus that mediates the speakers, says that there is a mediated communication.
The study of communication is broad and its application is even greater.
For semiotics, the act of communicating is materialization of thought or feeling in signs known to the parties involved.
These symbols are then transmitted and reinterpreted by the receiver.
Today, it is also interesting to think in new communication processes,
which encompass the collaborative networks and systems hybrids, which combine mass media and personal communication and horizontal communication.
