モバイルオペレーティングシステム
Mobile applications is software that connects to the middleware server and drives both the user interface and the business logic on the device. These applications are often able to transfer seamlessly across the Mobile operating system, as a platform to launch applications upon. Mobile apps can be deployed as "thick" applications—or native apps that are installed on the device—or rendered in the device's browser using technologies such as HTML5 (something that's often called the "thin" approach). Whether a "thick" or "thin" application is deployed depends on application complexity, device support, requirements for user experience, and the need for app availability in the absence of network coverage.
