Question

Quizplus · Accepted Answer

A black hole is logically impossible in a data flow diagram (DFD) because a process must act on input, shown by an incoming data flow, and produce output, represented by an outgoing data flow. A black hole, on the other hand, is a region of spacetime where gravity is so strong that nothing, not even light, can escape. This means that a black hole cannot receive input or produce output, making it logically impossible in a DFD.
