Computer cables are often made of copper.
My PC speaker cables have a copper wire, as well as a insulated (white) copper wire. The headphones (Sony) appear to have 3 wires in them - green, red, and orange. The links you posted are more for car/home theater speaker wire.
It depends on what kind of hub you mean. Some useful cables could be power cables, CAT 5e cables, fiber optic cables, etc.

Yes, If you have a Monitor and the cables to go with it, the cables can attach to the TV screen and you'll have a PC on a TV. But not on DVD, but the TV itself.
No you cant. I tried it and it didn't work. Sorry, pal.
Cables carry the electrical signals necessary to transfer data from one system to another.
No, internal PC wiring colors do not correspond to the standard AC wiring colors. Computer power supplies provide direct current to the computer and peripherals. When using direct current, the black wire is the ground wire. The red wire to the peripheral supply cables are 5 volt, and the yellow wire is 12 volt. Some SATA power connectors have an orange wire that is 3.3 volt.
Peripherals
You can't using telephone cables. Telephone cables use 4 wires, but none of the wires are twisted, so there will be problems with crosstalk. Also, telephone cables use an incorrect connector (RJ-11) for a NIC card in a PC, which needs RJ-45 connectors.
3 types of ribbon cables found in a PC are, a 34-pin floppy drive cable with twist, a 40-pin IDE cable with 40 wires, and a 40-pin IDE cable with 80 fine wires(80 conductor cable)A floppy drive cable, an IDE cable, and a CD or DVD drive cable

Yes as long as you have the right cords or cables.
