entête

An entête is a French term meaning "header" or "heading." In various contexts, it refers to the topmost section of a document, page, or message. The specific content and purpose of an entête can vary significantly depending on its application.

In the context of written documents, such as letters or official papers, an entête often includes sender and recipient information, the date, and a subject line. This provides essential details for identification and context. In web design, the entête, or header, is the top section of a webpage. It typically contains the site's logo, navigation menu, and sometimes a search bar, serving as the primary identifier and navigational hub for the user.

In digital communications like emails, the entête, also known as the header, contains technical information about the message's transmission, including sender and recipient email addresses, the path the email took, and timestamps. This technical entête is crucial for troubleshooting and understanding email delivery. Similarly, in data processing and programming, an entête can refer to a block of data at the beginning of a file or data stream that describes the content or format of the subsequent data. The term emphasizes its position at the beginning and its role in providing introductory or identifying information.
