WSDL is used to describe the availability of service.
8. What are the advantages of Restful web services?
These are listed advantages of Restful web services:-
1. Language Independent
2. Platform Independent
3. Fast
4. Use SOAP
5. Allows different data format
9. What are the advantages of SOAP web services?
There are some advantages of SOAP, which will be given below :-
1. Language Independent
2. Platform Independent
3. WS Security
10. What is Synchronicity?

2. Modularity
3. Interoperability
4. Cheaper Communications
5. Perfect Protocol for every application program
14. What is Interoperability in web service?
It is helpful to make easier communication with each other and share data even also services. While other applications can also use web services. Like, a VB or .NET application.
15. What is RPC?
