A device through which data and programs from the outside world are entered into the computer.

• A. Output Device
• B. Processor
• C. Storage Device
• D. Input Device

Answer: (D)

The concept being tested is how a computer receives data from outside sources. An input device is any hardware that brings data and programs into the computer for processing, acting as the entry point for information from the outside world. Examples include keyboards, mice, scanners, and microphones, which convert human actions or external signals into digital data the computer can work with. In contrast, output devices display or print results (like a monitor or printer), storage devices save data for later use (like a hard drive or USB stick), and the processor handles the actual computation. Those roles don’t describe the entry point for new data into the system, which is why an input device is the correct choice.
