Question

what is the recommended solution if a computer performs slowly? a. decrease the brightness of the display. b. install anti - virus software. c. install additional ram. d. verify if the ac adapter is connected properly

Explanation:

Decreasing display brightness affects power - usage not performance. Installing anti - virus software helps with security but may not directly speed up a slow computer. Verifying AC adapter connection is for power supply, not performance. Installing additional RAM can improve a computer's processing speed as it allows the system to handle more tasks simultaneously.

Answer:

C. Install additional RAM
