Whois & Analysis for vinylengine.com

The phonograph is a device invented in 1877 for the mechanical recording and reproduction of sound.

In its later forms it is also called a gramophone (as a trademark since 1887, as a generic name since c.

1900).

The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record".

To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound.

In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones.

In later electric phonographs (also known as record players (since 1940s) or, most recently, turntables), the motions of the stylus are converted into an analogous electrical signal by a transducer, then converted back into sound by a loudspeaker.

Information is that which informs.

In other words, it is the answer to a question of some kind.

It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts.

As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.

An image (from) is an artifact that depicts visual perception, for example a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.

Knowledge is a familiarity, awareness or understanding of someone or something, such as facts, information, descriptions, or skills, which is acquired through experience or education by perceiving, discovering, or learning.

An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages.

They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived.

Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes visible.
