Input source refers to any device, method, or medium through which data or information is provided or entered into a system, program, or device for processing or manipulation. It is essentially the origin or point of entry of data that initiates an action or triggers a response within a technological system.
In computing, an input source can encompass various hardware or software components, such as keyboards, mice, touchscreens, scanners, microphones, cameras, sensors, or even files and networks. These input sources allow users to communicate, interact, or transfer information to a computer, software application, or electronic device.
For example, when typing on a keyboard, the keys' input is transmitted as electrical signals to the computer, serving as an input source for text entry or command execution. Similarly, when swiping or tapping on a touchscreen, the touch input acts as an input source to navigate menus or interact with applications.
Furthermore, an input source can also refer to the specific software or data entity that provides input to a program or algorithm. It could be a file containing raw data, a database, an array, or any other form of data structure that serves as a source for computational processes.
In summary, an input source is the means or channel through which data or information is entered or provided into a system, software, or device, enabling interaction, processing, or manipulation to take place.
