Your laptop has an ExpressCard /54 slot. Which of the following statements is true?

  1. Compatible ExpressCards for the laptop only include cards that are square-shaped.

  2. You can use an ExpressCard /34 card or an ExpressCard /54 card in the laptop.

  3. Only ExpressCard /34 cards are compatible with the laptop.

  4. ExpressCard /54 slots cannot accommodate ExpressCard /34 cards.

The correct answer is: You can use an ExpressCard /34 card or an ExpressCard /54 card in the laptop.

The statement that you can use an ExpressCard /34 card or an ExpressCard /54 card in the laptop is accurate because of the design and compatibility features of the ExpressCard standard. The ExpressCard format comes in two sizes: /34 and /54, with the '/54' indicating a slightly wider slot that is capable of accommodating both sizes. This means that any device designed for the narrower /34 format can also fit into the wider slot of /54 without any issues. This compatibility is crucial for users seeking to maximize the functionality of their devices. The /54 slot also maintains versatility by being able to support a range of ExpressCards, allowing for various functionalities such as additional USB ports, networking options, or even video outputs depending on the cards used. Therefore, having an ExpressCard /54 slot enhances the overall usability of the laptop.
