In its most basic sense, a is a device or process used to selectively allow certain elements to pass through while blocking others. Whether it is a physical mesh catching coffee grounds or a complex algorithm screening spam emails, the fundamental goal remains the same: purification, isolation, or the removal of unwanted "noise" from a desired "signal".
