Hi Abhishek,
There are a lot of Tarot web-sites which cover the history of Tarot. I believe they usually explain the correspondance between current day playing cards & the ancient symbols of Tarot. One theory is that Tarot cards came from ancient Chinese currency. The Chinese had a game where they used their currency in gambling games & the money had symbols on it & was actually used like we use playing cards today. Other theories are that Tarot came from the Gypsies in Persia, Turkey & India And then moved west into Europe. Another theory claims that the very oldest & first Tarot cards were from Egypt. No one knows for certain.
Here is a link on the history of Tarot:

I believe there is information about the suits in regular playing cards & how they related to Tarot. The main difference between regular playing cards & that of Tarot is that playing cards of today do not have the 22 major arcana or trump cards. The only surviving member from that group into the modern game card playing deck is the Joker who I guess is either the Fool or Magician from Tarot.
If this link will not open then you should be able to copy it into your browser in order to view the article. Actually it's a book written by the (I think British) occultist S.L. MacGregor Mathers. If you search Dogpile or Google you can find a lot of information on Tarot's history & the connection to playing cards. You may even do a search to find a site which is solely about using playing cards as a divination tool. I am certain someone must have creted a site for playing cards.
If you are interested in a recent book about Tarot may I recommend, The Tarot : History, Symbolism, and Divination by Robert Place:

If you have trouble with this link you can easily find the book information on Amazon by searching via book title or author's name.
