Web clipping pages must be small and compact because they are designed for display on a small screen and travel over slow connections. Icons for web clipping applications are displayed in the Launcher application along with the icons for the traditional GUI Palm OS applications. This gives the appearance that the web clippings are stand-alone applications. Actually, they run inside a Palm OS application called the Web Clipping Application Viewer. If a user taps on a web clipping's icon in the Launcher, the Web Clipping Application Viewer is launched and displays the web clipping content.
Applications run one at a time.
In response, the Palm OS stops the current application and launches the newly selected one. Although Palm OS applications are event-driven, they may perform work outside of the event loop in response to other system requests. For example, if the user uses the Find facility to search the device for a particular word, each application is launched and asked to search its databases for a record containing data that matches. The same PRC runs on all Palm branded devices as well as all licensee devices such as Handspring, Symbol, or Sony. Some devices do have individual characteristics that can be coded to.
