USER INTERFACES
THEORY
3. Command Line Interface
| Advantages | Disadvantages |
|---|---|
| If the user knows the correct commands then this type of interface can be much faster than any other type 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 compared to other types of 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'. |
