Why do we need them? And, what makes them different?

ERC tokens are native to the Ethereum blockchain. Each token has a different use case. An ERC-20 is the standard token and allows for fungible and indistinctive tokens. That contrasts with an ERC-721 which is unique and non-fungible. The final ERC token, ERC-1155, combines fungible and non-fungible tokens in a single standard.
