Communication Technology

Communication is a process that allows beings - in particular humans - to exchange information by one of several methods. Communication requires that some kinds of symbols from a kind of language are exchanged. There are auditory means, such as speaking or singing, and nonverbal, physical means, such as body language, sign language, para language, touch or eye contact.

Communication happens at many levels (even for one single action), in many different ways, and for all beings, and some machines. Many or all, fields of study dedicate some attention to communication, so when speaking about communication it is very important to be sure about what aspect of communication one is speaking about. Some definitions are broad, recognizing that animals can communicate with each other as well as human beings, and some are more narrow, only including human beings within the parameters of human symbolic interaction.

The beginning of human communication through artificial channels, i.e. not vocalization or gestures, goes back to ancient cave paintings, drawn maps, and writing.

Our indebtedness to the Ancient Romans in the field of communication does not end with the Latin root "communicare". They devised what might be described as the first real mail or postal system in order to centralize control of the empire from Rome. This allowed for personal letters and for Rome to gather knowledge about events in its many widespread provinces.

The adoption of a dominant communication medium is important enough that historians have folded civilization into "ages" according to the medium most widely used. A book titled "Five Epochs of Civilization" by William McGaughey (Thistlerose, 2000) divides history into the following stages: Ideographic writing produced the first civilization; alphabetic writing, the second; printing, the third; electronic recording and broadcasting, the fourth; and computer communication, the fifth. The media effects what people think about themselves and how they perceive people as well. What we think about self image and what others should look like comes from the media.

While it could be argued that these "Epochs" are just a historian's construction, digital and computer communication shows concrete evidence of changing the way humans organize. The latest trend in communication, termed smartmobbing, involves ad-hoc organization through

Electronic media

In the last century, a revolution in telecommunications has greatly altered communication by providing new media for long distance communication. The first transatlantic two-way radio broadcast occurred on July 25, 1920 and led to common communication via analogue and digital media:

  • Analog telecommunications include traditional telephony, radio, and TV broadcasts.
  • Digital telecommunications allow for computer-mediated communication, telegraphy, and computer networks.

Communications media impact more than the reach of messages. They impact content and customs; for example, Thomas Edison had to discover that hello was the least ambiguous greeting by voice over a distance; previous greetings such as hail tended to be garbled in the transmission. Similarly, the terseness of e-mail and chat rooms produced the need for the emoticon.

Modern communication media now allow for intense long-distance exchanges between larger numbers of people (many-to-many communication via e-mail, Internet forums). On the other hand, many traditional broadcast media and mass media favor one-to-many communication (television, cinema, radio, newspaper, magazines).


Mass media

Mass media is a term used to denote, as a class, that section of the media specifically conceived and designed to reach a very large audience (typically at least as large as the whole population of a nation state). It was coined in the 1920s with the advent of nationwide radio networks and of mass-circulation newspapers and magazines. The mass-media audience has been viewed by some commentators as forming a mass society with special characteristics, notably atomization or lack of social connections, which render it especially susceptible to the influence of modern mass-media techniques such as advertising and propaganda.


Who

Communication in many of its facets is not limited to humans or even primates. Every information exchange between living organisms, a transmission of signals involving a living sender and receiver, can count as communication. Most of this, necessarily, is nonverbal. Thus, there is the wide field of animal communication that is the basis of most of the issues in ethology, but we also know about, Cell signaling, Cellular communication (biology), chemical communication between primitive organisms like bacteria and within the plant and [[fungi|fungal kingdoms. One distinctive non-intrinsic feature of these types of communication in contrast to human communication is allegedly the absence of emotional features, and a limitation to the pure informational level.
