Which HTTP method in a RESTful web service is typically used to replace a resource completely?

Explanation:
PUT is used to replace a resource completely. In REST, this method targets a specific URI and replaces the existing resource at that location with the full representation you send. If the resource exists, it gets overwritten with every field, making the operation idempotent—sending the same request multiple times yields the same result. If it doesn’t exist, PUT can create the resource at that URI with the provided data. Contrast this with PATCH, which applies partial updates to a resource rather than replacing it in full, and POST, which is generally used to create new resources or submit data for processing rather than to replace an existing one. For example, to update a user profile fully, you would send the complete user object to the user’s URI, and the server would replace the stored representation with what you provided.
