What bus connection is most commonly used for networking or modems?
A) CNR
B) PCI
C) PCIe
D) ISA
E) Maybe we should take the train
The answer: A) CNR
The Communications and Networking Riser was designed as a low-speed interface for network connections or modems. By using the CNR, you can avoid using a full PCI slot for these common low-speed devices. It’s unusual to find a CNR slot on most modern motherboards because these features have become integrated onto the motherboard itself.
