Which component is primarily used for data entry in a computer system?

• A. Monitor
• B. Keyboard
• C. Speaker
• D. Scanner

Answer: (B)

The keyboard is primarily used for data entry in a computer system because it provides a set of keys that allow users to input text, numbers, and commands directly into the computer. It is an essential input device that facilitates interaction with the operating system and applications by enabling the user to type information efficiently and precisely. When considering other options, the monitor serves as an output device that displays visual information and does not contribute to data entry. Speakers are also output devices that convey sound and audio signals but do not interact with data entry. While a scanner is another input device used to convert physical documents into digital format, its function is specific and not as versatile as that of a keyboard for general data entry tasks. Therefore, the keyboard stands out as the primary tool for entering data into a computer system.
