What is the primary function of input devices?

The primary function of input devices is to communicate instructions or commands to the computer. Input devices, such as keyboards, mice, scanners, and microphones, allow users to interact with the computer system by providing data and commands for processing. These devices convert user actions—like typing, clicking, or speaking—into a format that the computer can understand and process.

This is essential for the operation of any computing environment, as it enables users to perform a wide range of tasks, from simple text input to complex commands that initiate various software functions. While input devices can assist in the retrieval of information as part of an interactive process, their core purpose is to facilitate inputs that drive the computer's operations. Therefore, the primary role differs from options that involve data retrieval, storage, or graphical enhancement.
