SIGNAL (programming language)

A signal in programming is like a message that one part of a computer program sends to another part of a program. It's like when you pass a note to your friend in class. The note is like the signal and your friend is like the other part of the program. The signal tells the other part of the program that something happened or needs to happen. It can be used for things like stopping a program, pausing a program, or telling a program to do something specific at a certain time. It's like giving directions to a driver telling them when to turn or stop driving. Just like different signals mean different things in driving, different signals mean different things in programming.
