Where are a router's operating system files typically loaded?

The operating system files for a router are typically loaded from Flash memory. This storage medium is designed for non-volatile memory, which means it retains the information even when the router is powered off. Flash memory allows for faster access and modification of the operating system files necessary for the router's operation.

While CMOS and NVRAM are also types of memory found in routers, they serve different functions. CMOS is more commonly associated with storing system settings related to the hardware configuration, while NVRAM is typically used for saving the router's configuration file. A virtual disk, on the other hand, is generally associated with virtualized environments rather than traditional router architecture.

The significance of Flash memory in routers lies in its ability to support system updates and hold the necessary software that enables routing functions, configuration, and management features. Thus, the correct understanding of where the operating system files reside is crucial for networking professionals managing router systems.
