Mini IOS
A type of train/release which supports mid-range and low-end Ethernet LAN switching for Enterprise access and distribution networks, as well as mid-range 12.2SE, 12.2SG. and low-end SP Metro Ethernet networks.
SE, SG Train/Release
It stores the Router’s “Startup Configuration File” and retains data even when power is lost
NVRAM - Non-Volatile RAM
It is a proprietary kernel that provides routing, switching, internetworking, and telecommunications features.
Internetwork Operating System (CISCO IOS)
It is similar to computer memory chips. Loses all its data when rebooted or powered off, and this is where the IOS resides when the device is running
RAM - Random Access Memory
A type of train/release which consolidates releases and fixes defects. Inherits features from previous generation T train, and does not add additional features.
Mainline Train/Release
A component of the ROM that is a low level diagnostic utility that performs various tests on hardware components. It verifies that all necessary components are present and operational.
POST ( Power on self test )
It uses a hierarchical structure which requires entry into different modes to accomplish particular tasks.
