Google. We can say it is the best friend or best teacher of us, if any dout is there or some questions are there in mind we can freely ask to google and within few second we get the answer it also depend on your internet speed that within sec. We will get ans. Or will take some time. But anyway google is best, if we have some persnal douts or persnal questions that we can't ask to friends or can't ask to family doctor or even can't ask to family member then at that time we can freely take help of google we can ask persnal douts because no one is seeing you.
On google every information we can get about history of any country or anything you want all will be on google so thats why it also known for search engine. So I just love google it is the best way to clear your all douts.
