What are additional components that accomplish input, output, and storage functions called?

Peripheral devices are essential components that perform input, output, and storage functions in a computer system. They are external to the main computer architecture and extend the capabilities of the computer. Input devices, such as keyboards and mice, allow users to send data to the computer. Output devices, like monitors and printers, present data to users. Storage devices, including external hard drives and USB flash drives, provide additional capacity for data storage beyond what is available in the computer's internal memory.

The term "peripheral" encompasses all these devices, emphasizing their role in enhancing user interaction and data management. Each type contributes to the overall functionality and performance of the system by enabling the smooth flow of information between the user and the computer. Thus, recognizing the importance of peripheral devices is vital for understanding how computers operate and interact with external elements.
