Which of the following is considered a peripheral part of hardware?

Peripheral hardware refers to devices that are not part of the core computer architecture but are used to provide additional functionality. Output devices are a prime example of this category. They include devices such as printers, monitors, and speakers, which allow the computer to convey information to the user.

In contrast, the central processing unit (CPU), random access memory (RAM), and motherboard are all integral components of a computer system. The CPU is the main processor responsible for executing instructions, RAM stores data temporarily for quick access, and the motherboard serves as the main circuit board that connects all components. Since output devices operate outside the main internal components and provide specific functions related to user interaction, they are classified as peripherals.
