Explanation
A docking station expands a laptop's connectivity by providing additional ports, including multiple video outputs, beyond what the laptop itself offers.
Common mistakes.
- B. A VGA to DVI converter only changes the signal format between two connector types - it does not add a second video output where none exists.
- C. An adjustable monitor arm is a physical mounting accessory that holds a display in position - it has no role in generating or routing video signals.
- D. A PCMCIA card is a legacy expansion card format used for adding functionality like modems or storage - it is not a standard solution for adding multiple video outputs on modern laptops.
