1. Apple iOS(iphone operating system) is a handheld device operating system developed by Apple. Apple announced this system for the first time at Macworld conference on June 9, 2007. Originally designed for iPhone, it was later applied to Apple products such as iPod touch, iPad and Apple TV. Like Apple's Mac OS X operating system, iOS is based on Darwin, so it belongs to a commercial operating system similar to Unix. Originally, this system was called iPhone OS, until it was announced to be renamed as iOS at the WWDC conference on June 7, 20 10.

2.IOS (Internet Operating System-Cisco), Cisco network configuration system. IOS is a complex operating system, which is optimized for Internet interconnection-similar to the local operating system (NOS), such as Novell's NetWare, and optimized for LAN. IOS provides unified rules for maintaining the Internet economically and effectively for a long time. In short, it is a software architecture separated from hardware. With the continuous development of network technology, it can be dynamically upgraded to adapt to changing technologies (hardware and software). IOS can be regarded as an Internet hub: a highly intelligent administrator who is responsible for managing and controlling complex distributed network resources.
