Controller node vs Computer Node


I am fairly new to the OpenStack, and am trying to set up a simple network using Neutron. I dont understand the difference between a controller node and a compute node. Can anyone please help me out with this?

1) What is the function of both?

2) Do we always need both of them?

Thanking in anticipation.
