Let's start today with a quick review of important RAM / ROM / Flash / NVRAM info! ROM: Read-Only Memory . ROM stores the switch’s bootstrap startup program, operating system software, and power-on diagnostic programs (POSTs). ROM content is retained on reload. Fl ash memory : Generally referred to simply as “flash”, you’ll find IOS images here. Flash is erasable and reprogrammable ROM. Flash content is retained on a reload. RAM: Random-Access Memory . Stores operational information such as routing and switching tables and the running configuration file. RAM contents are lost when the router is powered down or reloaded. NVRAM: Non-Volatile RAM. NVRAM holds the router’s startup configuration file. NVRAM contents are not lost on a reload. Coming In April 2020!
