What is the link between devices and the computer?

Devices are hardware components that connect to a computer to enhance its functionality and user experience. They can be input devices, like keyboards and mice, which allow users to interact with the computer, or output devices, like monitors and printers, which display or produce results. Additionally, storage devices, such as hard drives and USB flash drives, provide ways to save and retrieve data. Together, these devices work in conjunction with the computer's software to perform various tasks and operations.
