Which term refers to external devices that connect to a computer to expand input/output capabilities, such as printers, keyboards, and external drives?

• A. SFP
• B. Wireless
• C. NFC
• D. Peripheral devices

Answer: (D)

External devices that connect to a computer to broaden input/output capabilities are called peripheral devices. This term covers items like printers, keyboards, external hard drives, mice, scanners, and similar gear that sit outside the main computer but extend what it can do. They connect through various ports and interfaces and aren’t built into the computer itself, unlike internal components such as CPU, RAM, or a motherboard. The other options describe technologies rather than a broad category of hardware: a transceiver used in networking, or wireless/NFC practices, which are communication methods rather than the general class of devices that expand I/O. Peripheral devices fit the description exactly by grouping these external expanders under one common name.
