In most places, for residential, no. For commercial, most jurisdictions require a contractors license for anyelectrical work. Where I live, there is a low-voltage license that is less than a full-blown electrical license that is used by fire alarm, security, and telecommunications contractors. The NEC and most jurisdictions define low voltage as less than 30 volts. Check with your local building department to be sure!
An electrical conduit is a system for routing and protecting electrical wiring. A cable conduit can be found wherever electrical wiring is needed. This includes wiring in appliances or in the walls of a home.
In conduit is way better option. Protects the cable from people digging around it. At least will hit conduit before hitting the wire. Also protects the cable from whatever is placed in the hold when backfilling
No, the electrical code requires that the mineral insulated cable be strapped at proper intervals and not be piggy backed on to other conduit structures.

For cable not in conduit and intended to be installed without conduit, such as NM cable, yes. You must provide some form of connector that will hold the cable in place. A clamp is not the only kind of connector that will do this but is the most common.

The outer casing of an Ethernet cable does not have a UV rating and will deteriorate under the summer sun. Pull the cable into a conduit and if possible bury the conduit underground. This will give you a safe and secure link.

If the voltage is supplying any current through the cable, i.e. if there is any 'load' at the end, then the voltage will drop through the cable.
It will decrease the voltage drop.
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
Voltage Grade of cables specifies the safe voltages which the insulation of the cable can withstand.
The advantage of using armoured cable over rigid conduit systems is the flexibility of the cable. There are some situations where conduit can not be bent into the shade needed to make a proper connection to a device. Because of the flexibility if the armoured cable it can be used instead to make a presentable looking job.
