Functions
Input Function accepts the input data from
outside the system.
Storage Function retains input data and
retrieves stored data.
Processing Function calculates and in other
ways manipulates the input and stored
data.
Output Function produces results of
processing for use outside the system.

How Users Use Information
Systems
Users may use an information system directly
by pressing keys on a computer keyboard or
by operating a piece of equipment that sends
input data to a computer.
A user may use an information system
indirectly by having someone else enter the
data and receive the output which is then
given to the user.
