Explanation
On Cisco routers, the startup configuration is stored in NVRAM (Non-Volatile RAM). NVRAM retains its contents even when the router is powered off or rebooted. When the router boots, it loads the startup config from NVRAM into RAM as the running configuration. The running configuration lives in Dynamic RAM (DRAM), which is volatile. BootROM holds the bootstrap program, and Static RAM (SRAM) is used for other purposes such as the route cache. Knowing the distinction between startup-config (NVRAM) and running-config (RAM) is a core networking concept.
