Mind Map




           2012/11/27
Types of Interface
1. Graphical User Interface (GUI)
 A type of user interface that allows users to interact with
electronic devices using images rather than text commands


2. Command Lines Interface (CLI)
A means of interaction with a computer program where the
user issues commands to the program in the form of
successive lines of text (command lines)




                                                        2012/11/27
Evaluation of GUI and CLI
                GUI                             CLI
Advantages      •   More user friendly          • Can occasionally present
                •   Suitable for beginners        certain actions that are
                •   More interactive              completely unavailable in a
                •   Ability to embed media        GUI
                                                • Easy to integrate with
                                                  scripting and other
                                                  programmatic interfaces
Disadvantages   • Need significantly more       • Steeper learning curve
                  memory (RAM) to run           • Unsuitable for beginners
                • Take up a much larger         • Not efficient for
                  amount of hard disk space       multitasking
                • Use more processing power     • Frequent input errors
                • Can be slow for experienced
                  programmers to use


                                                                     2012/11/27
