Flash in a router refers to a type of non-volatile memory used to store the router's firmware, operating system, and configuration files. Unlike volatile memory, which loses its data when powered off, flash retains information even when the device is turned off. This allows the router to boot up with the necessary software and settings each time it is powered on. Flash memory can typically be updated or erased, allowing for firmware upgrades and configuration changes.

Where does a router store its IOS in the long term?
A router stores its IOS (Internetwork Operating System) in non-volatile memory, typically in Flash memory. This allows the IOS to persist even when the router is powered off or restarted. The configuration files, which define how the router operates, can also be stored in NVRAM (Non-Volatile Random Access Memory) or Flash, depending on the setup. This ensures that the router can boot up with the correct operating system and settings.
