Answers
Answer:

• No need to learn complex commands/language
• Easier for a novice to learn/use
• Ideal when there are a limited number of options (efficient)
Disadvantages
• Can be frustrating for experienced users i.e. the command they want to use is buried 5 levels deep!!!!
• User interface may be limited by screen space and number of options available
Menu Driven Applications
• ATM
• Mobile Phone
• MP3 Player
• Video recorder
• Household Devices
• Digital/Cable TV
iii. Graphical User Interface (GUI)
Uses windows, icons, menus and pointers (WIMP) which can be manipulated by a mouse (and often to an extent by a keyboard as well).
Most suitable interface for inexperienced or novice users but…
UIs use more system resources than other types of interface
Many generic packages for a GUI will share common features
• Layout of the screen
• Names given to commands
• Icons
• Order of menus
• Mouse operation
• Dialog boxes
