We explain what they are and what are the communication channels. In addition, how they are classified, what they are for and when they are efficient.
A communication channel is the physical medium through which a communicative act is carried out , that is, it serves to exchange information between a sender and one or more receivers.
The presence and availability of this specific environment is only one of the essential elements to the communication circuit is met so effective . It is extremely important, since every act of communication requires the transmission of information through a specific physical element.
For example, right now, the information contained in this text is reaching its readers after it has been transmitted on a computer network , using satellite signals (microwaves), fiber optic cables or radio broadcasts (WiFi). These are examples of communication channels.
However, a frequent use of this term, in the corporate world, refers to the ways available to customers of a business in their communication with those who conduct it: email , phone numbers, message boxes, etc.
In addition to the channel, other essential elements for the communicative act are the code, the sender, the receiver and the message.
Communication channels can be, in broad strokes, of two types:
Another classification of communication channels distinguishes between unidirectional and bidirectional channels , that is, if the sender is always a sender and does not assign the turn to the receiver or receivers (such as radio, for example), or if it is a channel reciprocal communicative, which allows the recipients to be emitters also alternately (such as the telephone).
As said before, the communication channels are the physical support of the communicative act, its material part. Without them it would be impossible to transmit information
. This becomes evident when a communicative channel is indisposed, for example, as occurs when the telephone line is broken and our call is badly heard.A communication channel is more or less efficient , depending on its ability to transmit information reliably , that is, without being lost or adulterated along the way. A simple way to understand this is to remember that game in which the participants are placed in a wheel, and at some point in it a message starts, telling someone in the ear.
That person will say it to the ear the next and so on, until they turn around, without being allowed to repeat or clarify what has been said. Once the message has arrived at the last of the wheel, it must say it out loud, and it will be verified how much has been lost from the original message. That will be an indicator of channel efficiency.
There are many possible channels of communication. Next, we will detail some examples:
