This depends on the signal and the type of cable. Standard definition digital video signals can be run for 1000 feet or more with low loss broadcast standard cable. HD is limited to around 400 feet with the same cable. However, there are always lower loss cables available to extend the maximum distance. In the home, co-ax cables are often good for in excess of 100 feet although it depends very much on the signal source, the receiver and the cable itself.
It depends on the surround material, temperature, type of cable, and what you mean by "maximum current rating". Typically a maximum load current rating will be specified, such as 15A; this means you can push 15A through that cable nonstop without damaging it (it won't overheat). You might have a short time rating as well, such as a 4 hour rating, where the cable can handle runing 22A for 4 hours if the surrounding temperature is kept to some value, though this may slightly degrade the insulation. There's also a fusing current rating for many cables. At this current, the cable will eventually melt (like a fuse).
The NM represents the type of sheath on the cable. NM stands for Non Metallic sheath cable..
ACT has thermoplastic insulated wires. AC is old MC is the modern cable.

The BNC (Bayonet Neill Concelman) connectoris a very common type of RF connector used for terminating coaxial cable.There is no predetemined maximum length for the coax cable. The maximum length of cable is going to be governed by determining the input signal level, the minimum output signal level, and the signal loss based on the length of the cable between the input and minimum output.
50 feet is quoted as a maximum cable length for RS232 but that limit has been extended in practical applications to far longer distances. The practical limit depends on the data rate, the type of cable and the environment in which it is installed. RS232 is being replaced by other communication interfaces so although it can be extended further than the strict limit quoted by the standard, long cables will normally use other methods.

Single-Mode Fiber Optics: 20 Miles Multi-Mode Fiber Optics: 3000 Feet This is the maximum length you can have for each type of cable without using something such as a hub to continue the signal.
It depends on the type/speed. For 100 mbit/s twisted-pair (CAT5/6), it's 100 metres, for 1000 mbit/s - 1 gBit/s it's also 100 m *with the correct cable* and no sneaky tight bends/ overdone cable ties. The older coaxial cables gave 185 m, 500 m, but these are obsolete. The longest total length for ethernet is 100m, or just a bit over 300 feet. That is for pure cable lengths between any device that would regenerate the signal, such as a switch or hub. The problem is if the signal is to degradded by the time it reaches the device it can't be regenerated properly.
That depends on the type of cable and which one you bought.
10BASE2 is a variant of Ethernet that uses thin coaxial cable. The 10 comes from the maximum transmission speed of 10 millions of bits per second, The BASE stands for baseband signaling, and the 2 supposedly refers to the maximum cable length of 200 meters.
It depends on the TYPE of interface, meaning, if it's a USB cable it can only be a MAXIMUM of 5 Meters long. However, USB repeaters can be bought for about $20 that extend that cable 16ft. You can piggyback the repeaters but this is expensive. 36ft cables A-B also exist for about $45. In extreme cases you can also buy a USB over CAT5 adapters that will send that signal up to 350ft! These retail around $80 and your average CAT5 cable is $20-40 for a 100ft to 350ft length. IEEE1284 DB25 to Cenntronics (Old Style) cables come in 100ft lengths however there are 5 standards of communication SPP, ECP, EPP etc... the higher speeds dont like being extended past 25ft but this varies due to cable impedance and controler output. It may be wise to use a USB over CAT5 extender and then a USB to Centronics adapter if this needed to be longer then 50ft. I have been selling these solutions for the past 15years and know I am right. =)
