Answer
Header, Payload, Signature. Frame the concept in practical terms so you can explain it during interview discussion.
A JWT (JSON Web Token) consists of three parts: the Header, which specifies the signing algorithm used; the Payload, which contains claims or user data; and the Signature, which ensures the token's integrity. For example, in an e-commerce application, the payload might include the user's ID and roles, while the signature verifies that the token has not been tampered with.
