That is how some language scientists describe the special lingo of electronic communications and computing professionals. In simple English, what the scientists mean is that users, network engineers and others of the computing profession communicate by means of a carefully constructed shorthand. Supposedly, this unique speech is understood by everyone in the communications and computing community because they are all on the same wavelength, figuratively as well as literally. To expedite communication, the computer industry is laded with acronyms, special words and clipped phrases. The phrase ethernet is often used when 10baseT would be more appropriate.
Every professional discipline has special clipped terminology.
Become an expert in yours. The whole body of science we call semantics is devoted to the study of words and the significance of their meaning. Words are symbols that take on a special sense according to our own personal experience. Thus, people use words very differently. A common error is to assume that you are understood merely because you have said something directly to the other person involved, or that you think you are the most important, the most ranked, or the most controlling person in the communication chain or system.
