An ethernet cable is used in computer and internet connections and is available in different lengths and is also called an Ethernet Cable
Would probably depend upon the gauge of the cable, the type of metal used to conduct the electricity, what kind of shielding/jacketing around the wire, and how many breaks there are in the cable i.e. crimped butt connectors if applicable.
That would probably depend on the specific technology, but in the case of UTP or STP, the length limitation is 100 meters.
A cable that links a PC to a TV is often referred to as a VGA/HDMI cable. These cables can be purchased at various lengths from all good electronics stores, such as Amazon.

what type of cable would you used to create a ring topology?
Coaxial, RG-59.
Ethernet cable is typically 8-core category 5 (CAT5) cable with RJ45 plugs on each end, capable of bi-directional network transmission up to 100m. CAT5e and CAT6 are better quality cable for network communications over longer distances.
The first variety is UTP or unshielded twisted pair, often used in LAN's with maximum cable length of 100m. The second one is STP or shielded twisted pair, extensively used for telephones.
decameter (though this is not widely used)

The VGA cable that you would use to connect a laptop to a projector screen is called a PS2 projector cable.
