Input devices are hardware components that allow users to interact with a computer or other electronic systems. Common examples include the keyboard, which lets users type text, and the mouse, which enables point-and-click navigation on a screen. Other input devices include scanners, which convert physical documents into digital format, and microphones, which capture audio. These devices play a crucial role in how we communicate with technology. They translate user actions into data that the computer can process. For instance, when you press a key on a keyboard, it sends a signal to the computer, allowing it to understand your input and respond accordingly.
