Final answer:
The incorrect system flowcharting symbol description among the options provided is 'punched card,' as this symbol is no longer commonly used due to the obsolescence of punched cards in modern computing.
Step-by-step explanation:
In system flowcharting, specific symbols are used to represent different types of actions or steps in a process. The descriptions given for these symbols include:
- General purpose input-output: Typically represented by a parallelogram, this symbol is used to denote the inputting or outputting of data in a system, whether it is entering data manually or displaying results on a screen.
- Manual process: Shown as a rectangle with vertical lines on the sides, this signifies a process that is done manually rather than automatically by a computer or machine.
- Multiple-page document: This is indicated by a rectangle that has a corner folded over, often used in conjunction with sequential numbers to represent the continuation of a document over several pages.
- Punched card: A symbol with a corner cut off diagonally opposite to the multiple-page document symbol, representing a card with holes punched in it to store or provide information to be processed by a machine. The description provided for the 'punched card' is incorrect here as punched cards are now largely obsolete and have been replaced by more modern forms of data storage and input.
