In my Excel 2010, in DATA tab ---> From Other Sources ---> I have Microsoft Query.

I read from the internet, there is something else with the word "query", but the name is Power Query.
I cannot find this Power Query in my Excel 2010, and from the internet
I learnt that it seems I have to download first then install the Power Query to my Excel.

My question:
What is the difference between Microsoft Query and Power Query ?

Any kind of respond would be greatly appreciated.
Thank you in advanced.
