Shielded welding needs a gas to shield the weld from the atmoshere air. Unshielded uses a flux the burns when welding to shield the weld from the atmoshere air.
Sorry, there is no "ground wire" for a microphone. Commercial microphones have shielded symmetric wiring. Cheers ebs
It simply means that the ground wire is not grounded. There are two HOT wires and the unshielded copper ground wire which should be connected some how to the earth (ie. grounded)
The key is the protection of the wires. If you are using single wires you will need a conduit of some sort. Don't just run the single wires in the wall. Multi wire Romex or metallic shielded cable are used to provided added protection to the encased conductors.
The form of radiation shielded by atmosphere is Ultraviolet. The Ultraviolet is a part of radiation released by our star sun.
No
the shielded speaker is better

Shielded cable, when the shield is properly grounded, will minimize the amount of EM noise that reaches the shielded conductors.
Ethernet cable being shielded or unshielded twisted pair or CAT 5.
UTP is unshielded. Cheaper. STP is shielded.. more expensive.
Twisted pair wire is placed inside a thin metallic shielding, similar to aluminum foil, and is then enclosed in an outer plastic casing. The shielding provides further electrical isolation of the signal-carrying pair of wires. Shielded twisted pair wires are less susceptible to electrical interference caused by nearby equipment or wires and, in turn, are less likely to cause interference themselves. Because it is electrically "cleaner," shielded twisted pair wire can carry data at a faster speed than unshielded twisted pair wire can. The disadvantage of shielded twisted pair wire is that it is physically larger and more expensive than twisted pair wire, and it is more difficult to connect to a terminating block.
That would be STP versus UTP. STP provides more protection from interference, due to the shielding. "S" stands for "shielded" in this case. "U" means "Unshielded".That would be STP versus UTP.

UTP Is unshielded and STP is shielded UTP generally being bulkier and more expensive.
A type of unshielded wiring used in fire alarm systems sometimes called securex
RJ-45
It improves performance It maintains strong signals over longer distances It reduces electromagnetic interference and emissions
