title: Understanding of web services; SOAP, REST, JSON, XML
body: <p>Whenever i look for a job advertisement they expect this &quot;Familiarity with web services&quot; or &quot;Understanding of web services&quot; thing.</p>
  <p>So what exactly they expect from us?
  Do they want us being able to use existing web service APIs in our applications  or being able to know how to develop a web service from scratch?</p>
  <p>I am really confused because developing a web service from scratch should be a difficult task especially if you are not working in a company and a student like me. May be its because i haven't needed to develop a web service so far. I just use webservices in my application to show users some information. So i will be appreciated if someone explain this companies expectations i told u above..</p>
  <p>Thanks and Regards</p>
