Can you explain what is meant by 'Bounds' in programming or system architecture?

In programming, especially in user interface development (for example, iOS), the term "Bounds" refers to a rectangular area that defines the size and position of an object within its own coordinate system. This differs from "Frame," which describes the position and size of the object relative to its parent.

For example, in iOS, UIView has properties frame and bounds:

• frame — a rectangle in the superview's coordinates, defining the position and size.
• bounds — a rectangle in its own coordinate system, usually with origin (0,0) and size equal to the view's size.

Using bounds is important for operations within the object itself, such as drawing or handling touches.
