Description: A high-level protocol is a set of rules and conventions that operates at a higher layer of the OSI model, specifically in the application, presentation, and session layers. These protocols are fundamental for communication between applications and services on a network, as they provide services to application processes, facilitating interaction and data exchange. Unlike low-level protocols, which deal with data transmission across the network, high-level protocols focus on the semantics and structure of the data being exchanged. This includes aspects such as data encoding, session management, and information presentation. The relevance of these protocols lies in their ability to abstract the complexity of the network, allowing developers and users to focus on application functionalities without worrying about the technical details of data transmission. Examples of high-level protocols include HTTP, FTP, and SMTP, which are essential for web browsing, file transfer, and email sending, respectively.
