A sound card is what general type of computer component?

A sound card is classified as an Input/Output component because it facilitates the input and output of audio signals in a computer system. This device allows users to playback sound through speakers or headphones (output) and can also capture audio through microphones or other input devices. By processing audio signals, the sound card serves as the interface between the computer and external audio devices, enabling the user to interact with audio content both ways.

In the context of the other types of components listed, storage components are responsible for saving data, processing components handle computations and operations, and networking components manage communication between computers or networks. A sound card does not primarily fulfill these roles, which reaffirms its classification as an Input/Output device.
