What is REST?

REST (Representatonal state transfer) introduced by Roy Fielding in the 2000 defines web standards based architecture and uses HTTP Protocol for data communication. It revolves around resource where each component is a resource and a resource is accessed by a common interface using HTTP standard methods.

In REST architecture, a REST Server provides access to the resources and REST client accesses and presents these resources. Here each resource is identified by URIs/ global IDs. REST uses various representations formats like text, JSON and XML. JSON is the most popular format being used in web services nowadays.
