In a systems flowchart, which symbol is used to represent on-line data entry via a keyboard (that is, manual keying of input on an on-line terminal)?

Introduction / Context:
Systems flowcharts use standardized symbols to communicate processes, inputs, and storage in a technology-agnostic way. Clear symbol choice improves readability and prevents ambiguity between manual, batch, and on-line activities. This question targets the symbol for on-line keyed input.

Given Data / Assumptions:

• The input occurs on-line through a terminal/keyboard.
• The action is manual keying, not automated file transfer.
• We are selecting the appropriate standardized symbol.

Concept / Approach:

The on-line keyboard symbol (sometimes depicted as a keystation/terminal) indicates data captured by a user at an on-line device. This differentiates it from the generic manual operation symbol (manual processing that is not necessarily on-line) and from on-line storage symbols (disks/databases) that hold data rather than collect it.

Step-by-Step Solution:

Verification / Alternative check:

Most systems analysis symbol sets (e.g., ANSI/ISO-influenced) include a distinct icon for on-line input/terminal entry.

Why Other Options Are Wrong:

Manual operation symbol: A generic manual process, not specifically on-line entry.

Online storage symbol: Represents files/databases, not the act of entering data.

“Keeping operation symbols”: Not a standard term.

Common Pitfalls:

Using storage symbols to imply input; keep input, processing, and storage symbols distinct for accurate documentation.

Final Answer:

Online keyboard symbol
