How did culture find out how to text nouns, and what make nouns be recordable by machines?
also in a more modern vogue..how a voice sound can be stored surrounded by a computer or whatever.
how the heck is nouns made into a file or stored contained by tape? I dont find it.
Answers: Here's a little history how Edison get started with his phonograph experiments.

It have already been discovered that microphones use a moving diaphragm that vary its movement in accordance near the sound top that press on it. The diaphragm causes change in a voltage analogous to the characteristics of the nouns wave. (Hence, the residence Analog, although it wasn't coined at that time.) The larger the movement, the louder the sound representation, and the faster movement exhibited the frequency. In a phonograph dictation, the electric current is applied to a needle which cuts a groove to journal the analog to the sound. The depth of the groove, as all right as the spacing of the ridges, define the loudness and frequency. For playback, the conflicting process is used. A needle rides the groove, picking up vibrations which dispatch an electrical analog signal to a speaker that also has a diaphragm. The diaphragm again moves surrounded by accordance to the signal, forcing volumes of air to move which reproduces the nouns waves.
With IC technology, analog-to-digital (A-D) converters can assign a specific number for respectively nuance of a nouns signal. And with the precision of laser technology, such numbers can be stored surrounded by an incredibly microscopic area. Again, playback newly uses the reverse process requiring a D-A converter.
