Hi Nageswar,
The link provided by crossland answers all of your questions. If you don't mind please refer the manuals and the post your questions(i mean doubts). I know you are new and I am new to this too. I have been reading the manuals and that's helping me a lot. All these guys are already irritated with the stupid questions of the newbies. So please limit your "How to's". Also you cannot learn everything in one day .
