Which functions are associated with an AMR riser card?

1. Video and Network

2. Modem and Audio

3. Power and Cooling

4. Storage and Display

The correct answer is: Modem and Audio

An AMR (Audio/Modem Riser) card primarily supports audio and modem functionalities within a computer system. These cards are designed to enhance the system's ability to manage audio input/output and modem communication without taking up valuable PCI slots, as they connect directly to the motherboard via a specialized connector. The B option, which includes modem and audio, aligns perfectly with the purpose of an AMR riser card. The intended use of the AMR card allows for improved sound quality and efficient modem function, both crucial for tasks such as voice communication and data transmission over telephone lines. The other functions listed in the choices do not accurately represent the roles of an AMR riser card. Video and network are typically handled by other components such as graphics cards or network interface cards. Power and cooling functions are managed by the power supply and cooling systems, while storage and display aspects are related to hard drives and video output configurations, which are not the focus of an AMR card. Therefore, the choice of modem and audio accurately reflects the functions associated with an AMR riser card.
