Concept:

The Type of the system is the number of poles present at the origin.

The Order of the system is the total number of poles.

Ex: Transfer function 

The number of poles present at the origin = 2

So the type of the system = 2

And since the total number of poles = 3

So, the order of the system = 3

 

Analysis:

 

∵ there is one pole at the origin, the type of the system is 1.
