What are the component categories defined by the OpenStack architecture, and what do they do?

What will be an ideal response?

OpenStack architecture defines a number of components that can be divided into Control, Compute, Network, and Storage categories. OpenStack Compute components define the standards for the Hypervisor and associated modules need to run virtual machines. The control components are responsible for managing the configuration and authorization in the OpenStack environment. Storage components are used to store virtual machines, images, databases, and message files. The network components are used to connect internal components as well as provide gateways to external networks.
