The question has already been answered, but I wanted to post this pic I found in Wikipedia of a rig with FOUR, count 'em, four trailers.

If you had a trailer that had wheels both in the front and rear, then the entire load would be supported by the trailer and none of the load would be supported by the truck pulling it. Semi trailers are called that because they only have wheels in the rear, so only half the weight of the load is supported by the trailer; the other half rests on the truck pulling it, the semi tractor.
So a trailer designed with no front axle is called a semi trailer; a truck designed to pull a semi trailer is a semi tractor.

Semi- is a prefix to a verb, noun, or adjective meaning "half
The entire vehicle is the truck half plus the trailer half

It means they are half (semi) of the whole truck. The semi refers to the cab or tractor section only.
The other half is the trailer.

No idea, but I could guess.
We call them artics in GB (articulated lorries).
