In respect to this, what is a pipeline in coding?

In software engineering, a pipeline consists of a chain of processing elements (processes, threads, coroutines, functions, etc.), arranged so that the output of each element is the input of the next; the name is by analogy to a physical pipeline. Connecting elements into a pipeline is analogous to function composition.

What is a Cicd pipeline?
