The frets don't nessicarily make the noise, but the tension on the frets as you get higher on the fretboard is what makes the noise.
It's the strings that make the sound. They vibrate when you pluck them producing a sound. The sound is amplified in the body of the guitar(acoustic guitar). The frets enable you to vary the length of the strings thus making them produce a different sound.
the frets make the guitar string make a different sound.
The neck of a guitar as no other name than that -- the neck. This is the part of the guitar that connects the body to the head of the instrument. Located on the neck are the frets and the fretboard. In addition, all of the guitar strings rest slightly above the fretboard. In short, "the neck" is already a technical term. It doesn't have a special name to make it sound fancier.
The fear of playing badly. Ok I will try to explain this as good as I can. Each dot on the guitar represents a fret. The first dot is the 3rd fret, the second dot is the 5th fret, the 3rd dot is on the 7th fret and so on. Guitars have 22-24 frets on the fretboard. Count them, start from the very top... was that helpful? The frets are the strips of wire across the neck of a guitar. When you press a string against a fret you change the strings length and so it vibrates at a different frequency and produces a different sound.
it may be a few different things, but its probabley that you have the strings too close to the frets. for example, if you play up on the 12th fret or so, and the strings are extremley close to the frets, the string might be resting on two frets, so no sound comes out. it also could be that you arent pushing hard enough on the fret or not holding the fret down in the correct spot. hope this helps!
Not all guitars have frets, however, it is probably best to learn using frets.
Because it is not a guitar
If your finger is just lightly held over a guitar or bass string it is called a "muted note". In order to produce a sound on a guitar or bass you must either have you finger placed firmly on one of multiple frets. When no frets are held that is called an open note, or string.

The guitar produces a sinusoidal wave referred to as a tone. The pitch of the tone can be adjusted by pressing different frets and plucking different strings.

Yes but metal frets will let the string resonate better
