Using cross product to determine if vectors are parallel

[aero_zeppelin]

My question is simple:

I understand that if u x v = 0 , then u and v are parallel, but what does that 0 mean?
You can't obtain 0 by crossing two vectors. By 0, does it mean (0,0,0)?

Yes, it means the zero vector, (0,0,0) .
