 The information's Quantitative properties are defined by the static and syntactical laws of encoding, while its qualitative properties are defined by the semantic and pragmatic laws.
-**Statistical approach** examines the measurability of the information.
+==== Different approaches / levels ====
+**1.) Statistical approach** examines the measurability of the information.
 This level deals with the quantitative aspect of information. It focuses on the measurement and transmission of data, emphasizing the volume, redundancy, and entropy in a communication system. This approach is highly relevant in fields such as information theory (e.g., Shannon's theory), where the goal is to determine the efficiency of information encoding, transmission, and storage without considering the content or meaning of the data.
-**Example**: Measuring how much data can be transmitted over a communication channel while minimizing errors.

+**2.) The Syntactical approach** examines the formal qualities using the theory of coding and language theory.
+The syntactical level concerns the formal structures and patterns used to represent information. This includes rules governing how symbols, letters, or words are combined according to a predefined set of grammar or syntax rules. The focus here is on structure rather than meaning, making this layer important in language theory and coding theory.
-**Syntactical approach** examines the formal qualities using the theory of coding and language theory as well.
+//Example//: Correctly encoding a message into a sequence of bits following a defined protocol.

+**3.) Semantic approach** examines the meaning of the so-called informational primitives according to given semiotic and signal theories.
+At this level, the focus shifts to the meaning of the information. The semantic layer is concerned with interpreting the symbols, determining their relevance, and understanding the relationship between them and what they represent. This is critical for communication theory, linguistics, and semiotics, where the meaning carried by the message must be extracted and understood.
+//Example//: Understanding the meaning of a sentence based on the relationship between words and what they represent in the world.

+**4.) Pragmatic approach** seeks the effect of information according to the results/reactions and the related behaviours.
+The pragmatic level evaluates how the information affects the receiver's behavior or decision-making process. It concerns the usefulness of the information, analyzing how the receiver reacts or changes based on the conveyed message. This is relevant in decision theory and behavioral sciences.

+**5.) The Apobetical approach** seeks the sender's intended purpose and the receiver's results. It has less meaning from an engineering point of view.
+The apobetical level focuses on the intent behind the transmission of information and the desired outcome. It examines the purpose for which the information is sent and how effectively it fulfils the sender's goal. Although less prominent in engineering, this level is significant in communication design and strategy.
