Answer to Question 1

Service-oriented architecture (SOA) aims to compose applications from platform-independent services of virtual components. SOA envisions an application as a loosely coupled cooperation between services that can be rendered and consumed transparently across a network, regardless of specific platforms that the nodes implement.
A virtual component is a component that relieves its consumers from the issues of its physical identity and complies with universally accepted standards instead of following proprietary protocols. The technology choice for virtual components has generally come down to Web services. A Web service is a virtual component that offers its services via standard Web protocols.
The adoption of Web services is gaining momentum. It offers one great benefit: it allows utterly disparate system to communicate with each other over the existing Internet by using standard Web protocols. However, besides performance penalties associated with any distributed scheme, Web services are stateless. As a result, it is the responsibility of the clients to keep state and ensure the integrity of transactions.

Answer to Question 2

FALSE
