Abstract  
 

The relative entropy will be introcuded first in classical information theory and then I move to the quantum setting.
Basic properties of the quantity will be discussed, in particular the monotonicity and application to the strong subbadditivity of the von Neumann entropy will be given.
The role of relative entropy in the hypothesis testing and sufficient coarse-grainings will be treated shortly.
