1. Designing a user interface may seem a simple and side aspect of the development of an entire application. In fact it is, perhaps, the most important part of the development of an application.

2. A good user interface should:

   • be attractive and pleasing to the eye allow the user to try out different options easily be easy to use use suitable colours for key areas use words that are easy to understand aimed at the type of user have help documentation

3. Features of GUIs include:

   • They are much easier to use for beginners. They enable you to easily exchange information between software using cut and paste or 'drag and drop'. They use a lot of memory and processing power. It can be slower to use than a command-line interface if you are an expert user. They can be irritating to experienced users when simple tasks require a number of operations.

4. Features of menu driven interfaces include:

   • They are easy to use as the user does not have to remember sets of commands. They are user friendly - you can often guess your way around the options. They can be irritating if there are too many levels of menus to move around - with a command-line interface you can go to the option required immediately.
