What components make up computer peripherals?

The components classified as computer peripherals primarily consist of devices that are not part of the core computer system but expand its functionality and usability. Keyboards, mice, and monitors serve as essential input and output devices—keyboards and mice allow users to interact with the system, while monitors display the visual output. These peripherals are fundamental to a computer's operation, making it possible for users to execute tasks, input data, and interface with software.

In contrast, the other options include components that do not fit into the category of peripherals. Lighting, cameras, and microphones can be considered peripherals in specific contexts, but they are not standard input or output devices for all computer systems. Processors, memory, and storage are integral parts of the computer's architecture itself, and network routers and switches primarily facilitate connectivity rather than directly interfacing with user input or output. Therefore, keyboards, mice, and monitors are the most representative examples of what constitutes typical computer peripherals.
