Elements of system:
A system’s objectives are expressed
in terms of output is needs to produce, the inputs are the data which are
processed while the output i.e. information are the outcome of the process.
In addition there are two more
components
i.
Control
It
makes the system to operate within tolerable performance levels. Control of the
system is the decision maker that controls the activities of accepting input,
process & producing the output.
ii.
Feedback
It
is the information on how well a system is performing & it is essential for
system modifications.
System
may use feedback for control the information generated by comparing results
with acceptable level of performance (standards) and informing the control
elements of the difference is termed as feedback.
In
feedback control the output is fed back to input. It allows to be majored
against some standards and making adjustment in the processing accordingly.
