What is meant by the term "hook" in programming? -


I've just heard the word "hook", while I was writing to a few people about a program I am here. I am unsure of what the word means, although I have conjectured from the conversation that the hook is a type of function. I searched for a definition but was unable to find a good answer. Can anyone be able to give me an idea of ​​this, to explain the definition, this word has a general meaning and maybe a small example?

Basically this code contains a place that allows you to tap into a module Provides behavior or something happens when the reaction occurs.
