Which two devices are examples of input devices?

• A. Mouse and Keyboard
• B. Digital Camera and Biometric Authentication Device
• C. Printer and Monitor
• D. Speaker and Microphone

Answer: (B)

Input devices are hardware components that allow users to provide data and control signals to a computer or other information processing system. The essential characteristic of input devices is their capability to capture and transmit data for further processing by the computer. In the case of a digital camera, it captures images which are then transferred to a computer for display, editing, or storage. This action makes it a direct means of inputting visual data into a system. Similarly, a biometric authentication device, such as a fingerprint scanner, captures biometric data (like fingerprints) and converts it into a format that can be processed by the computer. Both of these devices serve as input mechanisms, allowing the system to receive information which can be used for various applications, such as security verification or image processing. The other choices consist of devices that either output data or do not fit the definition of an input device. A mouse and keyboard are indeed input devices, but they are not the selected answer. Printers and monitors are examples of output devices, as they display or produce results rather than accept data. Speakers, while they can have some form of input, primarily serve as output devices for audio.
