Computer Concepts Module 5 Practice Exam

An input device is hardware that sends data into the computer, allowing you to interact with software. Keyboard, mouse, and microphone fit this role because each one captures something you provide: the keyboard converts keystrokes into digital signals, the mouse reports movement and clicks to control the cursor, and the microphone turns sound into digital audio data for recording or commands. Printer, monitor, and speaker are primarily used to receive data from the computer and present it back to you as printouts, visuals, or sound, respectively. External hard drives, network cards, and GPUs handle storage, connectivity, and processing tasks rather than actively capturing user input. Power-related items like a UPS, power strip, and fan are about power management and cooling, not feeding data into the computer.
