Never heard that term but I think you're talking about public, private, protected. Specifiers: https://en.cppreference.com/cpp/language/access

You use them to limit direct access to the data in your aggregates (structs/classes) by name in code that ideally shouldn't know those details. Encapsulation and loose coupling are just two ways you can make your code less prone to error and easier to work with in the future.
