Information technology (IT) the technology needed to process information using electronic computers to store, retrieve, transmit and manipulate data. IT is increasing the efficiency of human activities by automated data processing. Information technology and communication (IT&C) Information technology + network communications

"content" of the human mind

Data represents formal support of the information that is converted into numbers, letters, symbols, codes. Data has no meaning by itself, should be placed in a certain context to receive value.

Data obtained from the processing of information can act as information for a specific category of users or may remain simple data if they lose the quality of the new semantics.

informare (Latin) = to give shape, form. The significance is related to the transformation of something without form into another something having some form. Perhaps the most widely accepted definition is related to its character of novelty, by the addition of knowledge resulting from the reception of signals. We receive information when we find something that we did not know before.

Any human activity is generating information. (-) If an activity is more complex and dynamic, the volume of information grows and diversifies, so it tends to slow down or even block the decision-making. (+) The information ensures knowledge transfer from one generation to another, ensures access to the most advanced achievements of mankind.

Symbol - current state of some observable signal which persists for a period of time SS - Symbol Space – how many differences per symbol MS - Message Space – number of possible messages How many positions (yes/no questions - SS) we need for:

• 4 Coin flips
• 7 Numerical digits (0-9)
• 10 English letters word 2^SS = MS

Less information → Less surprise Information is as greater as more unlikely. In this sense, information is "improbability". The analogy with explosions - just like information, each explosion is different from the others, even if it is about the same event. Similar to information, explosions can not be stored. We can store only substances that trigger the explosion. We can store only the premises of information - the data

Knowledge is a sum of all information acquired over time in a particular field. Knowledge is something higher quality then data and information. Understanding is aimed at discovery of universal truths. Information → looking the difference as in depth as possible (the difference that makes a difference, the relationship between data). Knowledge → the discovery of patterns.

When knowledge generate beliefs, values that guide behavior of an individual we can speak about wisdom.

- Information: what? - Knowledge: Who, when, where, how? - Wisdom: Why? with what implications?
