Which characteristics define the ExpressCard /54 form factor? (select two)

  1. L Shape

  2. 40mm wide

  3. 34mm wide at the connector

  4. Rectangular shape

The correct answer is: L Shape

The ExpressCard /54 form factor is characterized by its distinct features, one of which is that it has an L shape. This design allows for a larger area of connector which accommodates various functions and interfaces. In addition to the L shape, the width of the ExpressCard /54 at the connector is 34mm. This measurement is important as it indicates the standard size dimensions required for proper fitting into compatible slots on host devices. While an ExpressCard /54 has a width of 54mm overall, the connector itself is narrower, allowing for a specific design that differentiates it from other forms, such as ExpressCard /34, which features a 34mm width overall. Understanding these characteristics is crucial for recognizing the compatibility and suitability of various ExpressCard modules with slots in laptops and other devices.
