What is the operating system and how are iOS different from another operating system?

If we understand the simplest terms, then there is an operating system which is in the middle of your user and a physical device. This software interprets commands of applications and it provides access to apps that have features of a device such as multi-touch screen or storage.

Mobile operating systems like iOS differ from other operating systems because they keep each app in their own protective shells that apps stay away from each other and can not tamper one another. This makes it impossible for a virus to infect these apps, in a mobile operating system, other types of malware actually exist. These protective shells, which are around the apps, pose the other limits as they keep these apps away from each other with direct communicating. IOS uses a different feature called Extensibility, which allows an app to communicate with other apps.
