Question

BlackTom AI · Accepted Answer

Question restatement: The problem asks which item is an input device.
Since the provided answer indicates 'c. Keyboard', we will focus on why a keyboard is classified as an input device and acknowledge that the options themselves are missing in the prompt.
Key idea: An input device is a hardware component that allows the user to provide data or commands to a computer. A keyboard fits this definition because it enables users to enter text, numbers, and other commands that the computer processes.
Reasoning for 'c. Keyboard':
- Primary function: Captures user keystrokes and translates them into digital signals that the computer can interpret as characters, commands, or control inputs.
- Interaction modality: It directly interfaces with the user to supply data, unlike output devices which only present information (e.g., monitor, printer).
- Examples of its role: Typing a document, entering search queries, issuing keyboard shortcuts, and providing command instructions.
If other hypothetical options were present, we could assess them similarly: input devices include mice, scanners, microphones, and touchscreens, as they all collect information from the user or environment to be processed by the computer. By contrast, output devices like monitors, speakers, or printers only convey information from the computer to the user and do not feed data into the system.
Note on options: The original prompt lacks the full list of answer choices, so while we can validate why a keyboard is an input device, we cannot evaluate the correctness of other unlabeled options here. Nevertheless, the key takeaway remains that a keyboard serves as an input interface for user data entry.
