End of Chapter Materials and Suggested Solutions Supplement Chapter A-Page Accounting, Information Technology, and Business Solutions 2/e by Hollander, Denna, and Cherrington Supplemental Chapter A: Flowcharts and Data Flow Diagrams Review Questions R1. Draw the flowcharting symbols and describe the use of each. Flowcharts are used to describe an entire information system or some portion of it. The entire information system contains input into a manual and/or computer process, and some type of output. The output may be distributed to users to aid in decision making or retained and subsequently used as input into another process. Refer to Exhibits A-3, A-4, and A-5 to view a sampling of flowcharting symbols. The symbols include: 1. Input: On-line Computer Device (Keyboard or Terminal) - This symbol is used to describe the entry of data into a computer through an online terminal/keyboard 2. Terminal Display - This symbol is used to show a computer-terminal display. It is often used in conjunction with the on-line computer-device symbol to show data being entered into a computer process using an on-line terminal. 3. Input and Output: I/O - The Input/Output symbol is used to display records and master files (such as the journals and ledgers used in accounting). A description of the input/output is entered on the face of the symbol. 4. Manual Processing - The manual-process symbol indicates a manual operation (such as completing forms or verifying amounts) often performed on, or with a document. 5. On-line Computer Processing - A description of the operation is entered on the face of the symbol. 6. Off-line Processing (or processing performed by a machine other than a computer) - A description of the operation is entered on the face of the symbol. 7. Manual System Off-line Storage - This symbol represents any storage of paper documents (e.g., file cabinet, safe, or shelves). Two types of files exist temporary and permanent. A temporary file is a storage device for documents that will be involved in subsequent processing. A permanent file is distinguished by a horizontal line across the top of the symbol. The method of document order or organization is denoted using an A (alphanumeric), N (numeric), or C (chronological). Whenever abbreviations or codes are used, you should place a legend on your flowchart to assist readers. 8. On-line Computer File Storage - This symbol is used to denote online files used for computer processing. A description of the file contents is entered on the face of the symbol. 9. Computer Disk File Storage - This symbol denotes files stored on magnetic disk medium. A description of the file contents is entered on the face of the symbol. 1
