What is mean by web services

Question

anybody give clear explanation about web services.pls

Answer 1

Web services define how internet applications/programs connect and communicate using standards and protocols.
In simple terms, let's say you develop a business solution accessed over the internet. You write a PHP program that returns certain information about a particular branch of the organization in a protocol like XML. Such that another program in another branch can receive that over the web and utilize the information. In this case, the PHP program is a web service.
