Operating System

The Internetworking Operating System, known as IOS, is a family of proprietary network operating systems used on router and network switch models made by Cisco Systems, packaging routing, switching, internetworking, and telecommunications functions into a single multitasking operating system. Although its code base includes a cooperative multitasking kernel, most IOS features have since been ported to other kernels such as Linux and QNX for use across Cisco products. Not every Cisco networking product runs IOS: some Catalyst switches run IOS XE, Cisco ASR routers run either IOS XE or IOS XR, and the Nexus and MDS switches Cisco makes for data center environments run the Linux based Cisco NX-OS instead.

FAQs

How widely is Cisco IOS deployed?

Cisco says IOS runs on millions of active systems, from home office routers to the largest service provider networks.

Cisco says IOS Software is running on millions of active systems, ranging from the small home office router to the core systems of the world's largest service provider networks. That figure comes from Cisco's own product page, so it is the vendor's description of its reach and not an independent count.
