Everything about Fidelity totally explained
Fidelity is a notion that at its most abstract level implies a truthful connection to a source or sources. Its original meaning dealt with loyalty and attentiveness to one's
duty to a
lord or a
king, in a broader sense than the related concept of
fealty. Both derive from the
Latin word
fidelitas, meaning "faithfulness."
In modern
human relationships, the term can refer to sexual
monogamy. In western culture this often means adherence to
marriage vows, or of promises of exclusivity or monogamy, and an absence of
adultery. However, some people don't equate fidelity in personal relationships with sexual or emotional monogamy. (For example, see
polyamory and
Open marriage.)
Fidelity also denotes how accurate a copy is to its source. For example, a worn
gramophone record will have a lower fidelity than one in good condition, and a recording made by a low budget record company in the early
20th century is likely to have significantly less audio fidelity than a good modern recording. In the
1950s, the terms "
high fidelity" or "hi-fi" were popularized for equipment and recordings designed for more accurate
sound reproduction, while "
lo-fi" music aims for "authenticity" over perfect production. Similarly in
electronics, fidelity refers to the correspondence of the output signal to the input signal, rather than sound.
The computer age has spawned the term
Wi-Fi in reference to certain groups of
wireless electronic devices. While the term
Wi-Fi has been popularly taken to be an abbreviation of 'wireless fidelity',
Wi-Fi is in fact a commercial brand owned by the
Wi-Fi Alliance, and has little to do with fidelity as a concept.
