What are the three key parts of computer hardware?

• A. Storage, Input/Output, Compute
• B. Processor, RAM, Storage
• C. Keyboard, Mouse, Monitor
• D. Network, Power, Case

Answer: (A)

Think about what a computer does: it processes data, stores data, and communicates with the outside world. Those functions map to three broad parts of computer hardware: compute, storage, and input/output. Compute is where processing happens—everything that performs calculations and logic, driven by the CPU or other processing units. Storage covers all places data is kept when it isn’t being used, like hard drives and solid-state drives, plus memory where data sits during active tasks. Input/output includes the devices and interfaces that bring data into the system and send results out—keyboards, mice, monitors, network adapters, and other peripherals. This grouping matters because it describes how information moves through a computer: you input data, it’s processed, and the results are stored or sent out. The other options focus on individual components or on items that aren’t one of the three broad functional blocks (for example, a single input device or a subset of I/O devices, or infrastructure like power and the case). So the classification of compute, storage, and input/output best captures the main roles of computer hardware.
