User Interfaces

User Interfaces

1. Graphical User Interface

   • Easy to use so speeds up the users work and there is no need to learn complicated commands
   • Windows normally uses this type of interface
   • There are icons and images which you click to go where you want to go
   • Takes long to get where you want to go and generally requires more memory than a non-graphical interface. Also, when it is not properly built, it can be very difficult to work with.

2. Command-line Interface

   • Linux and Unix commonly use this type of interface
   • Fast and reliable if command typed correctly and capable of more powerful tasks. Also, easier to customise options.
   • You type in a command and from there, it directly accesses the page.
   • Hard to use for beginners as navigation is often more diffucult. Not enough ability to easily multitask.

3. Menu driven Interface

   • Commonly used on TV's e.g. TV Guides
   • Easy to use and you know what you want to do.Also, the user does not need to memorise lots of commands
   • Takes some time surfing the menu to find the desired page so it's slow and also the options aren't visual.
   • There's a menu and contains list which you find what you want and click to go to the page.
