The usual procedure is to remove the old wire and replace it with new wire.
Use the 4 wire if possible. You would only use a 3 wire for an old appliance.You shouldn't if possible. The 3 wire has no neutral wire as the 4 wire does. Som applications require the use of a 3 wire and some don't.
It depends if you mean the telegraph or wiring. The telegraph was invented by Samuel Finley Breese Morse around 1832. If you mean just wire, nobody really knows who invented it. Wire is probably over 4000 years old.
Actually they have 3. A round ground, wide neutral, and narrow hot. If it only has 2 it is an old outlet with no ground wire. If that is the case in your home, I highly suggest you connect a jumper wire from the ground screw to the white neutral wire on the silver screw to provide some protection. Do this at every outlet in the home. Replace all the outlets in your home with new ones if they are so old they do not have a ground connection.
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D

Ground wire to neutral wire.

Just change the switch, The type of wire has no bearing. The insulation will be brittle. If needed wrap the ends in the box with electrical tape. Only other solution is replacing the wire which means ripping out the wall and ceiling to get to the wire.
it depends on how old the wire is and how wet it is but it can be possible

with a standard 1 pole light switch (one switch operating the light) it is black wire to black wire and white to white (non grounded)

If the wires are incorrectly connected the idea is that it will blow the fuse.
