Input devices such as keyboards and mice are used to provide data and instructions to the computer, while output devices like monitors and printers present processed information to the user. The key differences between the two include: (1) the direction of data flow, which goes from the device to the computer for input and from the computer to the device for output, and (2) how users interact - actively engaging with input devices versus passively receiving information from output devices. Understanding these distinctions is important for comprehending how users communicate with computers.

Feedback May provide tactile or visual feedback to Generate output that can be seen, heard, or
the user (e.g., keypress feedback). felt by the user.

Understanding the distinctions between input and output devices is crucial for comprehending how information is
exchanged between users and computers. These devices work together to enable users to interact with and receive
information from the digital environment.
