A signal is a sign, action, or transmitted unit of information used to convey a message from one point to another. Signals can be visual, auditory, electrical, or digital, and they are fundamental in both human interaction and technical systems. In everyday life, a signal can be a gesture, a sound, or a light that indicates something, such as a traffic light or a hand wave. In technology and engineering, it refers to data or energy transmitted over a medium, such as radio waves, cables, or networks, to enable communication and control.
