CUI consists of different components such as text box, icon, desktop, pointing device etc. It supports multi user and multiprocessing system, and it executes multiple programs simultaneously.
GUI is slow as lot of processing power is required to handle computer generated graphics. GUI requires more memory as it contains a lot of graphical components. It is easier to change the appearance of Graphical User Interface or GUI with a bunch of customizable options. Precision of GUI is less as compared to the CUI and Flexibility of GUI is more compared to the CUI.
