What is a key characteristic of the LPX form factor?

  1. Uses risers

  2. Supports PCI exclusively

  3. It is the largest motherboard form factor

  4. None of the above

The correct answer is: Uses risers

A key characteristic of the LPX form factor is that it uses risers to connect expansion cards to the motherboard. This design allows for a smaller and more compact form factor, making it ideal for compact computers and low-profile cases. Option B is incorrect because although LPX boards do have PCI slots, they also support other types of expansion slots. Option C is incorrect because the LPX form factor is actually one of the smallest motherboard form factors available. Option D is incorrect because LPX boards do have key characteristics, such as the use of risers, and are not simply nonexistent.
