Application Layer protocol define all of the followings EXCEPTAnswer :Message SyntaxMessage SemanticRules IP Address

Understanding the Options

1. Message Syntax: This refers to the structure of the messages in the protocol, including how data is formatted and organized.

2. Message Semantics: This focuses on the meaning of the messages, describing how the data is understood and what actions should be taken based on it.

3. Rules: This entails the guidelines or conditions that define how the protocol operates in different situations.

4. IP Address: This is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It does not fall under the application layer protocol definition.

Analysis

The first three options—Message Syntax, Message Semantics, and Rules—are directly related to how an application layer protocol defines the communication between applications. They cover how messages are formed, what they mean, and the regulations for their transmission.

In contrast, an IP Address is related to the network layer of the OSI model, which deals with the routing of packets across different networks, rather than the details of application-specific communication.

Final Answer

The correct answer is IP Address. This is not defined by the application layer protocol.
