Input interfaces are the means through which users provide data or commands to a computer or electronic device. Common examples include keyboards, mice, touchscreens, and microphones. These interfaces translate user actions into signals that the device can understand, allowing for interaction and control. Different types of input interfaces serve various purposes. For instance, a keyboard is primarily used for text input, while a mouse allows for precise navigation on a screen. Touchscreens combine both input and display functions, enabling users to interact directly with visual elements. Each interface plays a crucial role in enhancing user experience and accessibility.
