1) What is REST and RESTful web services ?
this is the first REST interview question on most of interviews as not everybody familiar with REST and also
start discussion based on candidates response. Anyway REST stands for REpresentational State Transfer (REST) its a relatively new concept of writing web services which enforces a stateless client server design where web services are treated as resource and can be accessed and identified by there URL unlike SOAP web services which were defined by WSDL.
