can anyone explain..?

Answer 1

The dApp uses a smart contract to handle the voting. Therefore the data resides within the Ethereum blockchain and inside the smart contract. Physically the data is "replicated" across the entire network to all its nodes (thousands).

You should check the Ethereum White Paper https://github.com/ethereum/wiki/wiki/White-Paper (and possibly also Yellow Paper) for more details on how the Ethereum network works.
