    Hi Suniti,

    JSON: JSON is a simple data format used for communication medium between different systems
    JSONP: It is a methodology for using that format with cross-domain ajax requests while not being affected by the same origin policy issue.

    Thanks.

    JSONP is a simple way to overcome browser restrictions when sending JSON  responses from different domains from the client. But the practical implementation of the approach involves subtle differences that are often not explained clearly. Here is a simple tutorial that shows JSON and JSONP side by side.

    JSON
    {"name":"stackoverflow","id":5}

    JSONP
    func({"name":"stackoverflow","id":5});

     

    Thanks

    Hi,

    To make it more simple -

    JSONP is JSON with padding, that is, you put a string at the beginning and a pair of parenthesis around it. For example:

    //JSON
    {"helps":"old","age":55}
    //JSONP
    onOff({"helps":"new","age":65});

    Hope this helps.
