When installing an express card in a laptop, a technician should be aware that the difference between ExpressCard/34 and ExpressCard/54 is which of the following?

Question

Options

• AThe width in millimeters of the card
• BThe memory on the card
• CThe power required to run the card
• DThe number of pins on the card

• A
  90% (35)
• B
  3% (1)
• C
  3% (1)
• D
  5% (2)

Explanation

The numbers 34 and 54 in ExpressCard designations refer directly to the physical width of the card in millimeters. An ExpressCard/34 is 34mm wide, while an ExpressCard/54 is 54mm wide. Both card types share the same connector interface, length, and thickness. The difference is purely the form factor width. This matters because a laptop with an ExpressCard/54 slot can accept both 34mm and 54mm cards (with an adapter), but a 34mm slot cannot fit a 54mm card. Memory (B), power requirements (C), and pin count (D) are not what the numbers represent.
