What is the consistency of UI?

But what exactly is consistency in UI design? Consistency in UI design is concerned with making sure elements in a user interface are uniform. They'll look and behave the same way. This helps constantly prove a user's assumptions about the user interface right, creating a sense of control, familiarity, and reliability.

How can different parts of the interface be consistent?
