Prelim 1-3 Flashcards
the science and
practice dealing
with the effective
collection, storage,
retrieval, and use of
information.
Information science
The energy and raw material transformed by the
system
Input
The process used by the system to convert raw
materials or energy from the environment into
products that are usable by either the system
itself or the environment.
Throughput
The product or service, which results from the system’s
throughput or processing of technical, social, financial and
human input
Output
Information about some aspect of data or energy
processing that can be used to evaluate and monitor the
system and to guide it to more effective performance.
Feedback
A system which is a part of a larger system. They can work
parallel to each other or in a series with each other
Subsystem
Neither system elements nor the system itself changes much over time
in relation to the environment
Static system
Dynamic system
The system constantly changes the environment and is changed by the
environment
Fixed, automatic relationships among system components and no give
or take with the environment.
Closed systems
Interacts with the environment trading energy and raw material for
goods and services produced by the system. They are self- regulating,
and capable of growth, development and adaptation.
Open systems
The overall purpose for the existence or the desired outcomes. The reason for being.
Currently, many organizations put their goals into a mission statement.
Goal
The line or point where a system or subsystem can be differentiated from its
environment or from other subsytems. Can be rigid or permeable or some point in
between. Systems or subsytems will engage in boundary tending.
Boundary
The tendency for a system to develop order and energy over time
Entropy
Objectives can be
achieved with varying
inputs and in different
ways
equifinality
The activities and processes used to evaluate input, throughput and output in order to
make corrections
Control or
cybernation
those forces that counter the driving forces. They
hinder change because they push the patient in the opposite direction. They
cause a shift in the equilibrium that opposes change.
restraining forces
The tendency of system to lose energy and dissolve into chaos
Negentrop
