Are dapps and smart contracts the same?

Decentralized applications are blockchain-powered websites, whereas smart contracts work as API connectors that connect DApps with blockchain. In decentralized applications, backend code runs on the decentralized program; on the other hand, a smart contract is a piece of DApp in the form of small code. In simple words, DApp utilizes smart contracts to function and directly connects a member with a provider. In brief, decentralized applications are the technical combination of smart contracts and front end working as a complete computer program. On the other hand, smart contracts are a small portion of DApps.
