What term describes devices such as printers and scanners that connect to a computer but are not part of the CPU?

• A. Internal device
• B. Peripheral device
• C. CPU core
• D. Cache

Answer: (B)

Printers and scanners are external devices that connect to a computer but aren’t part of the central processing unit. This category is called peripheral devices. Peripherals extend what the computer can do—printing output, scanning documents, or providing additional input/output—through connections like USB, Bluetooth, or network interfaces. Internal devices are components housed inside the computer case that are part of its core hardware, not something you typically attach afterward. The CPU core is the processing unit inside the processor itself, handling instruction execution, and cache is a small, fast memory located inside the CPU to speed up data access. Those elements stay inside the processor and aren’t external attachments like printers or scanners.
