Input and output devices serve distinct roles in computing. Input devices, such as keyboards, mice, scanners, microphones, and cameras, are used to send data to a computer, allowing users to interact with and control it. In contrast, output devices, including monitors, printers, speakers, and projectors, receive data from the computer and present it to the user. The primary difference lies in their function and the direction of data flow: input devices facilitate data entry into the computer, while output devices display or produce the results of the computer’s processes. This distinction is crucial for understanding how we interact with technology on a daily basis.
