What is the difference between a CUI and a GUI?

Two different types of user interface systems that are used in computers are CUI and GUI. CUI means Character User Interface and GUI means Graphical User Interface. They are both the same in that they are important for operating the systems, but they are different in that they have different features and they provide different types of control to the users.

It can only accept these commands in the form of text in MS DOS of command prompt. It does not understand images or graphics. This was the earliest user interface and is very primitive now.

In the early days of their use computers could only be operated through this type of interface which consisted of a black screen with white text. There was no mouse because the computers did not support such a device. This type of user interface is outdated but there is a modified version of CUI on the modern computers.
