• Can occasionally present certain actions that are completely unavailable in a GUI

• Easy to integrate with scripting and other programmatic interfaces

Disadvantages • Need significantly more memory (RAM) to run

• Take up a much larger amount of hard disk space

• Use more processing power • Can be slow for experienced

programmers to use

• Steeper learning curve• Unsuitable for beginners• Not efficient for

multitasking• Frequent input errors
