Question

Quizplus · Accepted Answer

ROM (Read-Only Memory) contains the firmware that is responsible for booting the router and performing POST (Power-On Self-Test) to check the hardware components. It is non-volatile memory, which means it retains its content even when the router is turned off or restarted. On the other hand, RAM (Random Access Memory) stores the running configuration and routing tables, but it is volatile memory that loses its content when the router is restarted or powered off. NVRAM (Non-Volatile Random Access Memory) contains the startup configuration, and Flash memory stores the operating system and other persistent files such as IOS (Internetwork Operating System) images, device configurations, etc.
