1. Overview of webOS > Palm webOS Architecture

Palm webOS Architecture

Palm webOS is based on the Linux 2.6 kernel, with a combination of open source and Palm components providing user space services, referred to as the Core OS.

You won’t have any direct interaction with the Core OS, nor will the end users. Instead your access is through Mojo and the various services. Users interact with applications and the UI System Manager, which is responsible for the System UI. Collectively, this is known as the application environment. Figure 1-11 shows a simplified view of the webOS architecture.

This overview is included as background to give you an idea of how webOS works—this information is not needed to build applications, so you can skip it if you aren’t interested.
