Hey @niteshbaniya,
Bitcoin($btc) is the household brand of crypto-currency, It is created by someone called Satoshi Nakamoto(No one knows his true identity). It is not a physical coin but have been accepted by some bodies as a method of payment.
Ethereum($ETH) is created after Bitcoin and that it has applications beyond being just a crypto-currency. Thus can be considered a generation 2 coin. It is decentralized and allows Smart contracts and distributed application.
Similar to Bitcoin, it can be traded as a digital currencies. Some bodies have also accepted it as a currencies to make exchanges for goods.
The key difference between this two coins is the programing language used. Ethereum uses Turning complete, Bitcoin counts on stack-based languages.
Do note that before you decide to make a purchase of either coin, you should gather more knowledge as you don't want to purchase something you are not familiar with! All the best! (:
