Final answer:
A physical data flow diagram provides a detailed representation of a system's internal processes, including implementation specifics, and can help identify bottlenecks, while logical data flow diagrams are preferred for easier communication among stakeholders.
Step-by-step explanation:
The advantage of a physical data flow diagram (DFD) compared to a logical data flow diagram (DFD) is that the physical DFD focuses on the implementation details of the system, such as how, where, and by whom the system processes are carried out. This contrasts with a logical DFD, which focuses on what the system does rather than how it is done, emphasizing the data flows and the functional requirements without incorporating the physical system elements. While a physical DDF might help in identifying potential bottlenecks and inefficiencies by providing a detailed representation of the system's internal processes, the aspect of allowing for easier communication and understanding among stakeholders is typically attributed to the logical data flow diagram since it abstracts away from the physical constraints and focuses on the overall system's functionality.
The advantage of a physical data flow diagram (DFD) compared to a logical DFD is that it provides a detailed representation of the system's internal processes. This means that it includes information on how, where, and by whom the activities are performed. This level of detail helps in understanding the system better and identifying potential bottlenecks and inefficiencies.
