What function is not typically associated with a CNR?

Audio
Modem
Network
Video

The correct answer is: Video

The function not typically associated with a CNR, or Communication and Network Riser, is video. CNR is primarily designed to support additional audio, modem, and network functionalities in a computer system. It allows for expansion cards that handle audio inputs and outputs, modem connections for telecommunication, and network connections for data transfer over networks. In contrast, video functions are usually managed by dedicated graphics cards or onboard video solutions, which are not the primary focus of CNR. The standard design of CNR does not include provisions for video processing, which is why this choice is the correct answer. The other options—audio, modem, and network—are all functions that CNR is intended to support.
