Keyboard input is converted into digital signals from "summary" of Code by Charles Petzold
When you press a key on your keyboard, it causes an electrical signal to flow through a circuit within the keyboard. This circuit is designed to detect which key has been pressed based on the location of the signal. Each key on the keyboard corresponds to a specific electrical signal that is unique to that key. The electrical signal produced by pressing a key is then transmitted to the computer as a digital signal. This digital signal is a series of binary digits that represent the key that was pressed. The computer can interpret these binary digits to determine which key has been pressed and can then perform the corresponding action, such as displaying a letter on the screen or executing a command. The process of converting keyboard input into digital signals is essential for allowing the computer to understand and respond to user input. Without this conversion, the computer would not be able to interact with users through the keyboard. By converting keyboard input into digital signals, the computer can process the input quickly and accurately, enabling users to communicate with the computer effectively.- The conversion of keyboard input into digital signals is a fundamental aspect of computer technology that allows users to input information into the computer and control its functions. It is a crucial step in the communication between humans and computers, enabling users to interact with and operate computers efficiently.
