What is CCNA IOS?

CCNA IOS

Cisco IOS is Cisco System's Internetwork Operating System software that powers its switches and hubs.

Think of Cisco IOS as being similar to Windows on a PC. The PC is the hardware, but you need Windows software to make the PC function.

Cisco IOS has both a command line interface (CLI) and a graphical user interface (GUI).

It is essential that you know both methods of configuring Cisco devices to pass your CCNA exam, in particular the CLI.
