Which type of card is attached to the motherboard to allow expansion cards to plug into them?

1. Adapter

2. Riser

3. Slot

4. Bridge

The correct answer is: Riser

A riser card is used in computer systems to provide additional expansion slots that allow expansion cards to be connected to the motherboard. Typically, motherboards have a limited number of expansion slots due to size constraints; riser cards help overcome this limitation by effectively repositioning these slots to create more space for additional cards. Riser cards can be especially beneficial in compact systems where vertical space is at a premium, such as in certain compact desktop computers or servers. They can be designed to accommodate multiple expansions in a single horizontal slot, allowing for installation of cards like graphic cards, network cards, or sound cards while maintaining a more efficient use of space. In contrast, other choices refer to components that do not directly provide the function of hosting multiple expansion cards. For example, an adapter modifies the interface of a device for compatibility, a slot represents the physical interface on the motherboard but does not encompass the additional functional capabilities of providing more expansion options, and a bridge typically links two separate buses or networks for communication rather than creating additional slots for cards.
