Understanding Cisco Router Memory Types

It's beneficial to differentiate NVRAM from other memory types utilized by Cisco routers:

* RAM (Random-Access Memory): This is the primary working memory of the router, where the running configuration (`running-config`) and the Cisco IOS (Internetwork Operating System) software are loaded during operationTheCisco1841 Integrated ServicesRouterprovides two fixed 10/100 (100BASE-TX) Ethernet ports, two integrated High-Speed WAN Interface Card (HWIC)slotsthat  It is volatile, meaning its contents are lost when the power is turned offNVRAMis where the startup configuration (called startup-config onroutersusing theCiscoconfiguration conventions) is stored.

* ROM (Read-Only Memory): This is a small, non-volatile memory that contains a boot loader program, which is essential for initiating the router's startup process, including loading the IOS from flash memoryCISCO 871 INTEGRATED SERVICES ROUTER - CommGear

Related Concepts and Troubleshooting

When dealing with Cisco routers, understanding the synchronization between the `running-config` and `startup-config` is important2025723—NVRAMuses a tiny 24-pin dual inline package (DIP) integrated circuit chip, which helps it to gain the power required to function from the  If a configuration change is made but not saved using the `copy running-config startup-config` command (or a similar command in older IOS versions), the changes will only be present in RAM and will be lost upon a reboot2016820—MostCisco2500routerswill have 2MB of RAM soldered to the system board (this amount, however, depends on the revision number of therouter),  This is where the concept of checking if the Cisco router's configuration has been written to NVRAM becomes relevantProduct Data Sheet0900aecd80630b58 | PDF | Router
