,This is the fundamental protocol for communication over the internet. Web services
often use HTTP methods like GET, POST, PUT, and DELETE to perform operations
on resources. - ✔✔HTTP

____ is a markup language used to structure data, while ___ is a protocol for
exchanging information in ___ format. ____ messages typically contain an envelope,
header, and body, which define the structure and content of the message. - ✔✔XML
and SOAP-

This XML-based language is used to describe the functionality of a web service,
including the operations it supports, the parameters they accept, and the data types
they return. This allows other applications to understand and interact with the
service. - ✔✔WSDL (Web Services Description Language)-

•Sends requests to the service and processes the responses. - ✔✔Service Requester-

•Optional component that stores information about available services.

•Helps service requesters find and discover services. - ✔✔Service Registry-

A popular architectural style that leverages HTTP methods (GET, POST, PUT,
DELETE) to interact with resources. - ✔✔REST (Representational State Transfer)-
