Screen design is often referred to as block mode. Block mode is a type of design that uses a static screen, one which cannot be resized the way a GUI screen can be. Unless a user is running an application in a window, block mode runs in what is called full-screen mode.
The following table summarizes the differences between the block mode design and GUI design.
