Which of the following are examples of peripheral devices? A. The software that runs on the computer. B. The CPU, memory, and storage devices. C. The keyboard, mouse, speakers, and monitor. D. The electrical outlets that the computer is plugged into.
Answer (1)
Peripheral devices are hardware components that are not part of the core computer architecture like the CPU, memory, or internal storage, but are instead connected to the computer system to add functionality. They are typically external and can be removed or attached as needed.
To determine which of the options given are examples of peripheral devices, let's examine each:
A. The software that runs on the computer - This is not a peripheral device; software is a set of instructions that tells the computer how to perform tasks, and it runs on the hardware.
B. The CPU, memory, and storage devices - These are core components of a computer, not peripheral devices. The CPU (central processing unit) does the processing, memory (RAM) is used for temporary data storage while the computer is on, and storage devices like hard drives or SSDs hold data long-term.
C. The keyboard, mouse, speakers, and monitor - These are considered peripheral devices. They are external to the core computer system and provide additional input, output, or functionality. The keyboard and mouse are input devices, the monitor is an output device, and speakers are output devices for audio.
D. The electrical outlets that the computer is plugged into - These are part of the electrical infrastructure and not peripheral devices themselves. They provide power but do not add functionality to the computer system itself.
Therefore, the correct choice is C. The keyboard, mouse, speakers, and monitor are examples of peripheral devices. These devices interact with the computer to allow users to input data, output results, and interact more effectively with the computer system.
