protocols at each layer of OSI model The OSI (Open Systems Interconnection) reference model is a conceptual framework used to understand network interactions in seven distinct layers. Each layer has specific protocols that facilitate communication and data exchange. Let’s dive into the OSI model and explore the protocols that operate at each layer. Application layer It’s responsible for providing an interface for the user to interact with application services or network services. Ex- Web browser (HTTP), Telne Presentation layer It’s responsible for defining a standard format to the data. The major functions described at this layer are: - Encoding-Decoding Ex- AVI-(video), WAV-(voice), JPEG (graphite), ASCII (text) Encryption-Decryption Session layer It’s responsible for establishing, maintaining, and terminating the sessions. Session ID is used to identify a session or interaction. Ex- Remote procedural call, Apple talk session protocol. Transport Layer It provides data delivery me
