Millions of people use mobile operating systems worldwide, powering a wide range of devices, from smartphones
to tablets and wearable technology. These systems offer users a wide selection of features, including calling and
messaging, internet and cellular data connectivity, multitasking capabilities, interactive user interfaces and access
to a wide range of third-party applications and services to enhance the user experience even further.
Types of mobile operating systems:
There are several mobile operating systems on the market today, but two of the most widely adopted are the
iPhone’s OS, Apple iOS, and Google’s open source OS, Google Android. These two mobile OSes take different
approaches to the mobile operating system and end-user experience.
Apple distributes the only devices that natively support iOS, and it takes a “walled garden” approach, in which
Apple regulates all mobile apps and services that can run on iOS devices. Apple developed iOS to run on its own
XNU kernel. Apple has also released several device-specific mobile operating systems, such as watchOS for the
Apple Watch and iPadOS for iPad tablets.
