Keyboard input refers to the process of entering data into a computer or other electronic device using a keyboard. This device consists of keys that represent letters, numbers, and symbols, allowing users to type text, execute commands, and control software applications. When a key is pressed, it sends a signal to the computer, which interprets the input and performs the corresponding action. Keyboards can be physical, like those found on laptops and desktops, or virtual, as seen on touchscreens. This method of input is essential for tasks such as writing documents, programming, and gaming.
