Those entities which perform no information processing activities for the system are called:

In a data flow diagram (DFD), an external entity symbol portrays a source or a destination of data outside the system.

Which of the following systems flowcharting symbols descriptions is incorrect? a. b. c. d.

A(n) ______________________________ specifies where, how, and by whom a system's activities are accomplished.

On a systems flowchart, a paper file is represented by a:

A(n) ______________________________ is a graphical representation of a system showing the system processes, data stores, and flows of data into and out of the processes and data stores.

Which of these represent a comprehensive picture of management, operations and information systems?

Processes that handle other-than-normal situations are called ______________________________ routines or ______________________________ routines.

System flowchart logic should:

Why do auditors and systems analysts use systems documentation?

A systems flowchart varies from a data flow diagram (DFD) because it:

Which type of data flow diagram specifies where, how, and by whom a system's processes are performed?

Which data flow diagram shows what activities the system is performing without having to specify how, where, or by whom the activities are accomplished?

When a transaction cannot be processed in a routine fashion because of an error or other processing problems, the transaction must be handled by a(n):

The following narrative describes the order entry process at Adams, Inc.: Narrative Description Adams, Inc. customers mail their orders to the Adams customer service center where clerks open the orders and review them for accuracy. The clerks then key orders into the computer. As the clerk is entering data the computer populates the order input screen with data from the applicable customer and inventory master data. The computer displays the completed order and the clerk reviews the order (assume there are no discrepancies) and then accepts the order (selects the "save" icon on the input screen). The computer then creates a sales order master record, updates the inventory master data to allocate inventory to the sales order, prints a picking ticket in the warehouse, and displays the sales order number to the customer service center clerk. The clerk then reads this number to the customer. Required: a. Prepare a table of entities and activities. b. Prepare a context diagram. c. Prepare a physical data flow diagram.

An information processing activity could be any of the following except:

A context diagram is a top-level diagram of a system that depicts the system and all its activities as a single bubble.

The following symbol represents a paper file.

On a systems flowchart a small circle represents a(n) ___________________

When the context diagram and the level 0 diagram have equivalent external data flows, the DFDs are said to be balanced.
