What is Cisco IOS




Cisco IOS (Internetwork Operating System) is the software that runs on most Cisco routers and switches. It provides the core functionality and features that enable network devices to communicate with each other and with other networks. Cisco IOS is based on a modular architecture that allows different components to be added or removed depending on the device model and configuration.


What is a Cisco 3845 router
