Question When to use normalization?

Hi all and Prof. Yaser,
Machine learning practitioners use to say that sometimes the input data should be normalized before an algorithm is trained on it. So, when should we normalize our input data? Put it another way, do all machine learning algorithms require normalization? If not, which ones require? And finally why is there a need for normalization?

Thanks bunches !
