whhere do stream come to play?

A vertex is composed of n streams.
A stream is composed of m elements.
An element is [position, color, normal, texture coordinate].
Still confused where stream come to play.
what relative does it with the mapping of the input vertex elements to the vertex input registers .
The use of streams is not required - it just allows us to more efficiently express some algorithms (e.g. Geometry Instancing). If you're having trouble understanding them, you could ignore them for now.
The runtime/driver composites the necessary streams together such you just get a single, complete, vertex by the time it gets to your vertex shader.
