can someone help me telling what is
RESTful and difference with `web Service'? i tried to search but i get confused between it and web service can anyone help ?
It's name clearly state its meaning that services provided on the web are called a web service
web service has two type REST API and SOAP API
RESTful Web Services are basically REST Architecture based Web Services. In REST Architecture everything is a resource. RESTful web services are light weight, highly scalable and maintainable and are very commonly used to create APIs for web-based applications.
SOAP (Simple Object Access Protocol) is a messaging protocol that allows programs that run on disparate operating systems (such as Windows and Linux) to communicate using Hypertext Transfer Protocol (HTTP) and its Extensible Markup Language (XML).
