Final answer:
A solid line with an arrow on a systems flowchart symbolizes the flow of data or sequence of operations.
Step-by-step explanation:
On a systems flowchart, a solid line with an arrow typically indicates the flow of data or the sequence of operations, showing how different parts of the system interact with one another. In other words, it is a visual representation of the data flow within the system, linking one process or activity to the next.
This is particularly useful in understanding how information moves through the different components of a process, allowing for identification of potential bottlenecks, redundancies, or efficiencies that might be gained.
The arrow points in the direction of the data flow or process sequence, helping to make clear the order of operations. Solid lines with arrows can also indicate specific actions like input and output, as well as the direction databases, documents, or information are transferred from one part of the system to another.
