3. Command Line Interface (CLI)

Advantages and Disadvantages
Advantages Disadvantages
If the user knows the correct commands then this type of interface can be much faster than other types of interface For someone who has never used a CLI, it can be very confusing
This type of interface needs much less memory (RAM) in order to use it than other user interfaces Commands have to be typed precisely. If there is a spelling error the command will fail
This type of interface does not use as much CPU processing time as others If you mis-type an instruction, it is often necessary to start from scratch again
A low resolution, cheaper monitor can be used with this type of interface There are a large number of commands which need to be learned - in the case of Unix it can be hundreds
A CLI does not require Windows to run You can't just guess what the instruction might be and you can't just 'have a go'.
