What constitutes Input in a computer system?

Input in a computer system is defined as any data that is submitted or transmitted to a computer for processing. This broad definition encompasses a variety of data types and input methods. Inputs can come from numerous sources, including but not limited to physical devices like keyboards and mice, as well as software-based inputs such as files, uploads, network requests, and sensor data. By acknowledging that input includes all forms of data sent to the system, we capture the full range of how users interact with the computer, not confined just to manual entry or specific types of devices.
