Which statement best describes the issue of distributed data processing (DDP)?a. The centralized and DDP approaches are mutually exclusive; an organization must choose one approach or the other.b. The philosophy and objective of the organization’s management will determine the extent of DDP in the firm.c. In a minimum DDP arrangement, only data input and output are distributed, leaving the tasks of data control, data conversion, database management, and data processing to be cen- trally managed.d. The greatest disadvantage of a totally distributed environment is that the distributed infor- mation processing unit locations are unable to communicate and coordinate their activities.e. Although hardware (such as computers, database storage, and input/output terminals) can be effectively distributed, the systems development and maintenance tasks must remain centralized for better control and efficiency.
