Trying to understand vectors a bit more.

What is the need for normalizing a vector?

If I have a vector, N = (x, y, z)

What do you actually get when you normalize it - I get the idea you have to divide x/|N| y/|N| & z/|N|. My question is, why do we do this thing, I mean what do we get out of this equation?

What is the meaning or 'inside' purpose of doing this.

A bit of a maths question, I apologize, but I am really not clear in this topic.

According to "Introduction to Neural Networks with Java By Jeff Heaton", the input to the Kohonen neural network must be the values between -1 and 1.
