     • Disadvantages - when it is not properly built, it can be very difficult to work with. - it generally requires more memory resources than a non-graphical one. - it might require the installation of additional software, e.g., the "runtime environment" in the case of java. - depending on the programmer, it might require more time to be implemented.

   • Advantages of GUI include: -You can create a more rich, and intuitive interface than is possible with CLI. -Most lay users will have a smaller learning curve using a GUI. -Complex, multi-step, dependent tasks can easily be grouped together in a way that discourages mistakes. -Ability to embed media
     • Disadvantages of GUI include: -Bloated software can waste memory, and reduce the performance of an application. -Sometimes it is more difficult to allow for advanced/power options in an "intuitive" GUI interface, than it is with a CLI. -Scripting a GUI interaction is not easily done unless it is just a set of repetitive tasks that don't require a lot of feedback, or actually testing the GUI.
