The majority of Cisco routers run the IOS, with its familiar command-line interface (CLI). Also, some routing cards in other devices run IOS. For example, the Route Switch Module (RSM) card for the Catalyst 5000 series LAN switches performs routing functions and executes the IOS. Each router has different types of memory, including RAM, ROM, flash memory and NVRAM. All these types of memory are permanent memory except RAM. No hard disk or diskette storage exists on Cisco routers.
