+**Information** is one of the basic concepts of 20th century science.
 According to our scientific physical world view, the material particles and objects in our world are constantly exchanging energy in the four-dimensional space-time continuum while their order changes.

-Information carries both quantitive and qualitative. Information is the characteristic of those groups which carry statical and structural meaning (and are constantly reacting to each other).

+Information can be used to achieve an individual's goals by enhancing that person's knowledge.
+====== The properties of information form a hierarchical structure ======
+There are usually between 3-5 levels in this structure, according to the researchers of this area.
+The most widely accepted structural layout is the 4-layer structure but if you take a look at the following model you may see 5 layers.

+The multi-level model of information is suitable for several kind of analyses (according to different aspects).
+The quantitative properties of the information are defined by the static and syntactical laws of encoding.
+The qualitative properties of the information are defined by the semantic and pragmatic laws.
+The statistical approach examines the measurability of the information.
+The syntactical approach examines the formal qualities with the use of theory of coding and language theory as well.
+The semantic approach examines the meaning of the so-called informational primitives according to given semiotic and signal theories.
+The pragmatic approach seeks the effect of the information according to the end results/reactions and the behaviors related to them.
+The apobetical approach seeks the sender's intended purpose and the results on the receiver's side.
+It has lesser meaning to the engineering point of view.
