This diagram shows three input devices connected to a computer.

• Keyboard: When the user presses keys, signals are sent to the computer.
• Mouse: When the user moves or clicks the mouse, signals are sent to the computer.
• Touchscreen: When the user touches the screen, signals are sent to the computer.

Arrows indicate the direction of data flow from each device to the computer, showing how user actions are input into the system.

Variations - 2 Challenges

[intermediate] Draw a flowchart showing the steps of how a touchscreen device processes a user's tap input and sends it to the computer.

[advanced] Draw a detailed diagram showing how keyboard input is processed inside a computer, including the keyboard hardware, signal transmission, and software interpretation.
