Which input device is used to capture handwriting and show strokes on the display?

• A. disk cache
• B. graphics tablet
• C. data bus
• D. computer architecture

Answer: (B)

Capturing handwriting and showing the strokes on the display is done by a graphics tablet. You write with a stylus on the tablet’s surface, and sensors detect the pen’s position (and often pressure). This data is sent to the computer, which renders the handwriting as strokes on the screen in real time. The other options aren’t input devices for handwriting: disk cache is a memory area to speed up disk access, the data bus is just a pathway for data inside the computer, and computer architecture is the overall design of the system. So the graphics tablet is the device that fits this function.
