Information and informaticsDef (information): profit and increase of knowledge, decrease of uncertainity (SH Atlas Informatics)

Def (informatics): discipline of systematic and automatic processing and transmission of information primarily by computers (SH Atlas Informatics)

Information content, unitsDef (information content): if one of n possible messages (x1,x2,..,xn) must be transmitted, and the probability of sending ith message is pi, then the average information content of the message is (Shannon):

Units of measurement:Bit Byte (B) kB MB GB TB PB
