what authority this person has to tell me dont ask this question....etc.
this is discussion forum. so I asked what I did not understood. If he dont like my question then no need to answer it. but why he is restricting me.

See below answer.

So, its significance: it's used. By what? That should be your question. But don't ask it. (I don't like open-ended questions .. go research.)

Yamini,

Don't worry about it. Sometimes people respond like that in order to hide the fact that they don't know the answer, or do not read your question carefully.

Just take it easy.

Sometimes, people may feel questions are duplicated, or asked the same questions many many times without read others.

So, some people may feel uncomfortable.
