Question

On a systems flowchart, a dashed line with an arrow going from one symbol such as that for a magnetic tape to a second copy of that same symbol indicates:

only some data are passed between the two devices the two devices operate simultaneously in parallel documents but not electronic data flow between the two devices
one copy is the original which is to be replaced after updating by the other copy

Answer 1

In systems flowcharting, a dashed line with an arrow between two identical symbols like magnetic tapes usually means the original data is being updated by the second copy.

Step-by-step explanation:

On a systems flowchart, a dashed line with an arrow going from one symbol such as that for a magnetic tape to a second copy of that same symbol typically indicates that one copy is the original which is to be replaced after updating by the other copy. This is a way to show that data is being transferred and the original will be updated with the new information. It's an important notation to understand in flowchart diagrams as it explains the flow of data and the updating process of data storage devices.
