'''IOS''' (short for "IOP Operating System" [https://wiki.wiidatabase.de/wiki/IOS]) is the operating system that runs on the [[Hardware/Starlet|Starlet]] (IOP) coprocessor ([https://wiiubrew.org/wiki/Hardware/Starbuck Starbuck] on the [[vWii]]) inside the [[Hollywood]] package. It provides services that are used by Wii code to access many system devices: USB, networking, security, app management, NAND flash storage, SD card, optical disc, and also WiiConnect24 features.

All software using the Wii SDK or libogc relies on a running IOS on the Starlet (with a few exceptions in the latter case - it is possible to shut down IOS services from libogc and work without it). Typically, the only times IOS is not in use is when running GameCube software (which uses [[MIOS]] instead - effectively a dummy IOS), or when [[BootMii]] and related software is in use (which uses [[mini]] instead).
