What is an Operating System & how is iOS different from other Operating Systems?

If we understand in simplest terms, then there is an operating system that lies between your (user) and a physical device (machine).

It interprets commands of software applications and provides access to apps that have features of the device such as multi-touch screen or storage.

Mobile operating systems such as iOS differ from other operating systems because they keep each app in their own protective shell ,

so that apps stay away from each other and cannot tamper with each other. This makes it impossible for a virus to infect these apps in a mobile operating system, similar types of malware do exist.

These protective shells that are around apps also pose another limitation as they keep apps away from communicating directly with each other.

iOS however uses a different feature called extensibility, which grants approval to the app to communicate with other apps.
