Sometimes, we use the word to imply multiple meanings in the same context!

There is a good reason for that. When writing code, we typically try to break the code base down into smaller units in order to manage complexity. For anything more than very simple programs, having a monolithic code base is not a good idea. That's why modular programming is a generally favored software design approach. There are two important ...
