ROM contains diagnostics executed on hardware modules.Flash memory does not lose its contents during a reboot.
Cisco router memory has over 120 gigabytes. That is a lot of memory for a router. This item can be found on either eBay or Amazon for a very cheap price.
Inside the router's chassis.
This is an incomplete command. However, this indicates that the running configuration will be saved on the device to a different location.
The bootstrap program that initializes a router's basic hardware components is typically stored in the router's ROM (Read-Only Memory). ROM retains its contents even when the router is powered off, allowing the bootstrap program to be accessible during the boot process. This program performs hardware checks, loads the operating system, and prepares the router for operation.
IP address remains the same. Mac address changes from router to router.
In a Cisco router, the memory that stores packet buffers and routing tables is known as Dynamic Random Access Memory (DRAM). DRAM is used for storing the operational data of the router, including routing information and temporary packet data during processing. In contrast, the router's startup configuration is stored in Non-Volatile Random Access Memory (NVRAM).
NVRAM, ROM, and flash memory
A router stores its configuration in the long term in a non-volatile memory called NVRAM (Non-Volatile Random Access Memory). This memory retains the configuration data even when the router is powered off. When the router is booted, it typically loads the configuration from NVRAM to the running memory (RAM) for operational use. Additionally, configurations can also be saved to external storage or backed up on a network server.
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.
