d) Graphical User Interface :

Graphical User Interface are great for beginners.
- This is because Graphical User Interfaces tend to be intuitive. This means that once you know about buttons, scroll bars and other controls, you can generally guess what you need to do next.

- There is often context sensitive help, and the interface will be designed to make it as easy as possible for the user to enter data.

- Because all of the features added to make the GUI easy to use, the actual software can sometimes be quite slow as processing time is taken up by the interface.

- Also, in order not to confuse the user with too much information, many commands are hidden and must be found by sing help manuals.
