Everything about Signal
Varying physical quantity that conveys information
A signal is both the process and the result of transmission of data over some media accomplished by embedding some variation. Signals are important in multiple subject fields, including signal processing, information theory and biology. Wikipedia →

📖 Definitions
Noun A sequence of states representing an encoded message in a communication channel.
Noun Any variation of a quantity or change in an entity over time that conveys information upon detection.
Noun A sign made to give notice of some occurrence, command, or danger, or to indicate the start of a concerted action.
Noun An on-off light, semaphore, or other device used to give an indication to another person. A railway signal.
