MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Web services are XML-based information exchange systems that use the Internet for direct application-to-application interaction. These systems can include programs, objects, messages, or documents. A web service is a collection of open protocols and standards used for exchanging data between applications or systems.

Detailed explanation-2: -Web services receive requests and send responses using widely used protocols such as HyperText Transfer Protocol (HTTP) and Java Message Service (JMS).

Detailed explanation-3: -A key feature of web services is that applications can be written in various languages and are still able to communicate by exchanging data with one another via a web service between clients and servers. A client summons a web service by sending a request via XML, and the service then responses with an XML response.

Detailed explanation-4: -XML is the data format used to contain the data and provide metadata around it, SOAP is used to transfer the data, WSDL is used for describing the services available and UDDI lists what services are available. A Web service is a method of communication between two electronic devices over a network.

Detailed explanation-5: -The aim of the Web Service protocols is to provide a means of describing data and behavior in a machine-processable way. Web Services use XML to describe metadata for discovery purposes and to define behaviour, and in general presume that XML documents will be the payload of the messages exchanged.
