A signaling system is a method used to convey information or instructions between different entities, such as people, machines, or systems. It can involve various forms of communication, including visual signals, auditory signals, or electronic signals. These systems are essential in many fields, including telecommunications, transportation, and computer networks, ensuring that messages are transmitted accurately and efficiently. In telecommunications, for example, a signaling system helps manage the setup, control, and termination of calls. It allows devices like telephones and cell phones to communicate with each other over a network. Similarly, in transportation, signaling systems, such as traffic lights and railway signals, help regulate the flow of vehicles and ensure safety on the roads and tracks.
