What is the role of sampling in multimedia?

Sampling in multimedia refers to the process of converting continuous signals, such as audio or video, into discrete data points for digital representation. This allows for the efficient storage, manipulation, and transmission of multimedia content. By capturing a limited number of samples at specific intervals, multimedia applications can recreate the original signals with acceptable fidelity, enabling playback and editing on digital devices. Proper sampling techniques are crucial to maintain quality while balancing file size and performance.
