The faucet use to be called a valve. The valve has been a way of shutting on/off water flow all the way back to the Egyptians, Romans and Greeks. The Romans helped to better the system by running water into buildings. In 1870 JH Davis got a patent on a globe valve.
There is a shutoff valve on the cold pipe going into the H/W tank, if you close it no water will come out of the tank. There should also be a shutoff valve on the wall below each faucet/tap.
No, the nut on the valve needs to be tighten. When you turn off your faucet, pressure in the line is increased and the seal in the valve is not tight enought to hold back the water. The brass or nylon coupling in the water shutoff valve may also be damaged and need to be replaced.
you have to turn off the supply and its usually a valve under the sink. if no shutoff there then turn off the main valve which is usually at the street at the meter box.

Outside Tap? outside faucet?/outside hosebibb?/outside spigot? well in most cases you are referring to the outside faucet that is dripping and I am guessing you have a ball valve or gate valve inside and when you shut of the ball/gate valve your outside faucet is still dripping and this means you have a leaky ball/gate valve which are known to leak slightly over the years and if your outside faucet is shutoff , then you need new seals in your outside faucet too. The easyest way to stop your leak is replace or repair your outside faucet if its a freezeless one. (just make sure your outside faucet has grade to drain the water out after you shut it off)

There are basically 3 precautions. :-1 People who know no better will hang a box containing fibre insulation around their outside faucets. This is next to useless.2 Smarter people install a shutoff valve inside the wall so they can stop flow until they need it. This is better, but a pain if it's installed in the crawlspace.3 Smart people get a 'frost free faucet' which is a faucet on the end of a 12 " tube and the handle outside operates a valve 12" inside the wall.
Flare copper pipe and use a flared shutoff valve. If valve isn't flared, use an adapter fitting between copper flared pipe and valve.

New pressure balance faucet or you can install a pressure balance valve in the water lines behind tub or if you have a crawl space you can install it on the water lines there. But install only too the lines to tub faucet. And they are not easy no matter where you install. I would just tell everyone not to use any water till you are done with shower.
