<P> Precise technical terms and their definitions are formally recognised, documented, and taught by educators in the field . Other terms are more colloquial, coined and used by practitioners in the field, and are similar to slang . The boundaries between formal and slang jargon, as in general English, are quite fluid . This is especially true in the rapidly developing world of computers and networking . For instance, the term firewall (in the sense of a device used to filter network traffic) was at first technical slang . As these devices became more widespread and the term became widely understood, the word was adopted as formal terminology . </P> <P> Technical terminology evolves due to the need for experts in a field to communicate with precision and brevity, but often has the effect of excluding those who are unfamiliar with the particular specialized language of the group .

Differences in jargon also cause difficulties where professionals in related fields use different terms for the same phenomena . </P> <P> With the rise of the self - advocacy movement within the disability movement, jargonised language has been much objected to by advocates and self - advocates .
