iOS is an advanced operating system from Apple, designed for iPhones and iPads. It is based on Mac OS X 10.5, which premiered in 2007. Thanks to iOS, all Apple mobile devices are efficient, functional and tailored to the needs of a specific user. Additionally, the iOS system offers all iPhone and iPad owners intuitive operation and multitasking. The functions of this operating system depend on the version you have. For example, iOS 11 allows you to store all materials in one place, and the announced iOS 12 will provide a higher level of parental control.

After the iPhone was launched, its operating system did not have an official name, it was usually simply called Mac OS X, to which it is similar. It wasn’t until March 6, 2008 with the release of the SDK for this system, that it was documented as iPhone OS. On June 7, 2010, the name was changed to iOS.

All software is individually released for circulation by Apple Inc. and distributed centrally from one repository (App Store) only by iTunes with a mandatory cryptographic confirmation signature. This distribution model, while not free, enables the prevention of the spread of malware while enabling centrally distributed fixes and recall, and hence, an unprecedentedly high standard of security and, intended, quality for the general public.
