Do you know that?/You know what? Do you know that?/You know what? Apple's mobile phone, iPod touch and iPad all run on a powerful operating system, which is the iOS developed by Apple for iPhone! Like Mac OS X, it is built on Darwin, bringing you a stable and efficient experience.

Four-level architecture

The charm of iOS system architecture lies in its four levels: core operating system layer, core service layer, media layer and touchable layer. These levels work together to make it easy for you to enjoy various functions and services. And this operating system only takes up about 240MB of memory space, which is really small and powerful!

Multi-touch user interface

The default main interface design of iOS4 is simple and intuitive. It can be directly operated by multi-touch, and it is easy to realize sliding, touch switch and key control. Interacting with the system is as simple as playing a game, just sliding, tapping, squeezing and rotating, all at your fingertips.

Design of built-in accelerator

The built-in accelerator allows you to change the direction of the screen by rotating the device, which is more convenient to use. This design really makes people fondle it!
