NVRAM Stores startup-config. The IOS (Internetwork Operating System) is stored in the flash. Both flash and NVRAM are non volatile storages but there is a major difference.

NVRAM is that router component in which start up configuration file is stored.

When a router boots up, it performs a series of steps, called the boot sequence, to test the hardware and load the necessary software.1. The router performs a POST. The POST tests the hardware to verify that all components of the device are operational and present. For example, the POST checks for the different interfaces on the router. The POST is stored in and run from ROM (read-only memory).2. The bootstrap looks for and loads the Cisco IOS software. The bootstrap is a program in ROM that is used to execute programs. The bootstrap program is responsible for finding where each IOS program is located and then loading the file. By default, the IOS software is loaded from flash memory in all Cisco routers.3. The IOS software looks for a valid configuration file stored in NVRAM. This file is called startup-config and is only there if an administrator copies the running-config file into NVRAM.4. If a startup-config file is in NVRAM. the router will load and run this file. The router is now operational. If a startup-config file is not in NVRAM, the router will start the setup-mode configuration upon bootup.

The SSID (Service Set Identifier) is typically stored in the firmware of a wireless router or access point. It can also be saved in the configuration settings of the device, which can be accessed through the router's web interface. Additionally, when devices connect to a Wi-Fi network, they may store the SSID in their operating system settings for future connections.
The basis difference between bridge and router mode in a Modem is to identify where does the user creditials are stored. In router mode, they are stored in the modem/router itself. In Bridge mode, creditials are stored on a pc and you would need to click on connection icon / connection to establish the connection KK@Melbourne
It is stored in memory until windows shuts down. The logical location (on the Hard Drive) is system32/config
