A vector can be represented as a product of unit of a vector and its magnitude.
All parallel vector will have the sane unit vector.
Naturally, the unit vector = vector/magnitude

basically, they need to have the same direction. (meaning that it can be along same direction or exactly opposite direction).
Furthermore, one can be expressed as a product of another with a scalar quantity. ex. xvec = constant * yvec
Also, it is possible for both to have the same unit vector as well.
Basically, what we consider parallel in case of straight lines is considered, but with slightly more conditions.
Let me know if this helps.

Parallel vectors have the same direction, but not necessarily the same magnitude. <1,1,1> is parallel to <2,2,2> but their length is not the same.

they can be expressed as a=kb where a and b are notations of vectors and k is a constant. they also can be in opposite or same directions. they can be connected end to end.
