    - Web service uses three styles of use: SOAP, REST and XML-RPC for communication whereas   API  may be exposed in multiple ways.

   -  Web service needs a network to operate but APIs don’t need a network to operate.

 30. What is REST?

- REST (Representational State Transfer) is an architectural style for developing web services which exploit the ubiquity of HTTP protocol and uses HTTP method to define actions. It revolves around resource where every component being a resource that can be accessed through a shared interface using standard HTTP methods.

- In REST architecture, REST Server provides access to resources and client accesses and makes these resources available.

 
- Each resource is identified by URIs or global IDs, and REST uses multiple ways to represent a resource, such as text, JSON, and XML.
