Input and output devices are essential components of a computer system, each serving distinct functions in the process of data handling and communication. Input devices allow users to provide data and instructions to a computer, while output devices present processed data in a user-friendly form. Every computer system relies on two main categories of devices to interact with users and the environment: input and output devices . These tools make it possible to enter data into the system and receive results after processing. Understanding them is essential for students and anyone interested in how computers work. Input devices allow users to interact with a computer by providing data or commands. Some common input devices include keyboards, mice, microphones, webcams, and scanners. Output devices allow users to see, hear, or otherwise perceive the results of the computer's processing.
