User Interfaces
▪ Users can give command to a device through the user interface. It is also called Human Computer Interface (HCI). There are several type of user interfaces
Command Line Interface
When using a CLI, users enter text instructions and the computer system provides results or feedback as text. • This type of interface is found in older systems or for devices with limited storage because it requires little memory. • Command have to be typed precisely because the interface only recognizes certain commands. Usually a help menu for users lists and explains the acceptable commands. • Advantage is that it is quick and straight forward to execute the commands

Menu Driven Interface
This type of interface displays a list of options as a menu. • Selecting one of these options will either trigger a command or display another menu with further options to choose from. • Menu driven interfaces are easier to use than CLI but take more time as you have to through the menu structure each time to carry out a command, rather than typing the command directly in to the system

For this reason, they sometimes check the instruction with the user before searching for a match. • The advantage is that hands-free operation is possible. This means that they used in GPS systems in vehicles in order to improve road safety
