iOS is the operating system that runs the iPhone, iPod touch, and iPad. It’s the core software that comes loaded on all devices to allow them to run and support other apps. The iOS is to the iPhone what Windows is to PCs or macOS is to Macs.Originally known as the iPhone OS, the name was changed with the introduction of the iPad.Apple added a form of limited multitasking soon after the release of the iPad. This multitasking allowed processes such as those playing music to run in the background. It also provided fast app-switching by keeping portions of apps in memory even when they weren’t in the foreground.
Mobile operating systems like iOS differ from most other operating systems because they put each app in its own protective shell, which keeps other apps from tampering with them. This design makes it impossible for a virus to infect apps on a mobile operating system, although other forms of malware exist. The protective shell around apps also poses limitations because it keeps apps from directly communicating with one another.
As of November 2016, Apple iOS market share was 12.5% worldwide, making it the second most popular mobile OS behind Google Android, according to IDC.

Support ended: n/a
Current version: 13.3.1, release Jan 28, 2020.
Initial version: 13.0, released Sept. 19, 2019
Perhaps the biggest change introduced with iOS 13 is that the OS no longer runs on the iPad. That’s due to the release of iPadOS (which begins with version 13). That’s a new OS dedicated to the making the iPad a more useful productivity device and a potential laptop replacement. It’s based on iOS 13 and has many of the same features, but also adds iPad-specific items.
Beyond that, iOS 13 shores up some core features, including launching apps faster, unlocking devices with Face ID faster, and overhauling pre-installed apps like Reminders, Notes, Safari, and Mail. Maybe the most obvious new feature is the Dark Mode, but the changes range much wider than that and further bolster the already-strong OS.
