What is an input device used for in relation to a computer?

An input device is designed specifically to transmit data to a computer. This allows users to interact with the computer by providing information or commands. Common examples of input devices include keyboards, mice, scanners, and microphones, all of which enable the user to input various types of data, such as text, images, or audio.

Understanding the role of input devices is crucial in the context of computing, as they serve as the primary means through which users control and communicate with their systems. While other devices, such as output devices, are responsible for presenting information to the user or storing data, input devices focus solely on capturing user input and delivering it to the computer for processing. This interaction is fundamental to the operation of modern computers, as it facilitates tasks ranging from simple data entry to complex commands.
