Higher-level modules are the ones that operate on a higher conceptual level (i.e. algorithms, domain logic, business rules, etc). In other words, they’re more abstract and they govern “what” the application is supposed to do. On the other hand, modules that contain more implementation-specific code (e.g. hardware, I/O, network, etc) are said to be lower-level.
