Molitor, "The Information Society: The Path to Post-Industrial Growth," Edward Cornish (ed.), As an individual and societal resource, information has some interesting characteristics that separate it from the traditional notions of economic resources.Unlike other resources, information is expansive, with limits apparently imposed only by time and human cognitive capabilities.refers to facts and opinions provided and received during the course of daily life: one obtains information directly from other living beings, from mass media, from electronic data banks, and from all sorts of observable phenomena in the surrounding environment.A person using such facts and opinions generates more information, some of which is communicated to others during discourse, by instructions, in letters and documents, and through other media.
On the commercial side, the information service industry has become one of the newer industries worldwide.
Its expansiveness is attributable to the following: (1) it is naturally diffusive, (2) it reproduces rather than being consumed through use, and (3) it can be shared only, not exchanged in transactions.
At the same time, information is compressible, both syntactically and semantically.
An abstract model of an information system features four basic elements: processor, memory, receptor, and effector ().
The processor has several functions: (1) to carry out elementary information processes on symbolic expressions, (2) to store temporarily in the processor’s short-term memory the input and output expressions on which these processes operate and that they generate, (3) to schedule execution of these processes, and (4) to change this sequence of operations in accordance with the contents of the short-term memory.Information organized according to some logical relationships is referred to as a body of knowledge, to be acquired by systematic exposure or study.
