Which of the following statements is incorrect with reference to GUI operating system?

Correct option is B

GUI-based systems use graphical elements like windows, icons, and images, which require more system resources. As a result, they tend to consume more power compared to simple command-line interfaces. Hence, the statement that GUI systems take less power is incorrect.

Important Key Points:

1. GUI systems are user-friendly but resource-heavy.
2. They require more memory and processing power due to graphical rendering.
3. Compared to CLI, GUI systems often perform slower and are less power-efficient.

Knowledge Booster:

• The statement about not changing system functionality is true in the context of GUI—it limits deep-level customizations unless advanced settings are accessed.
• GUI systems typically consume more memory due to visual components and background services.
• They are generally slower than CLI systems, especially on older hardware.
