Linux vs. Android

Fundamental Concepts

• Linux is an operating system kernel—the foundational layer of an operating system responsible for hardware interaction and resource management. 
• Android is a complete operating system built on top of the Linux kernel, specifically optimized for mobile and embedded devices. 

While both systems share the same core kernel, the key distinction lies in their purpose and design: Android offers robust tools for building user interfaces and end-user applications, whereas Linux is ideal for server environments. At PIERRE, our entire cloud infrastructure is powered by Linux.

What Do They Have in Common?

• The Linux Kernel: Android relies on a customized version of the Linux kernel, enhanced for better power management, real-time capabilities, and support for mobile hardware.
• The PIERRE Android Operating System
  • At PIERRE, we utilize a highly customized version of the Android Open Source Project (AOSP). This tailored OS is specifically engineered to run the Pierre system and all its dependencies. Notably, we do not integrate Google services (such as Google Play) or rely on third-party software updates, which differentiates our platform from conventional consumer Android devices. 
• Core Components and Services
  Each PIERRE display operates several critical services: 
  • PIERRE Launcher
  • Manages Over-The-Air (OTA) updates for system components, distributed via the PIERRE infrastructure.
  • Handles firmware updates, including embedded modules such as Zigbee.
  • Updates device drivers, including multimedia codecs (e.g., H.264/H.265).
  • Configures network interfaces and maintains routing tables.
  • Controls peripheral functions such as audio, screen brightness, and more.
  • PIERRE Application
  • The main user-facing component designed to deliver the core functionality of the PIERRE platform.
  • Edge Services
  • Facilitates local device interconnectivity and authorization management within the PIERRE ecosystem. 

Seamless and Modular Updates

Thanks to its modular architecture, the PIERRE system supports transparent updates that occur without interrupting the user experience. Users also have the option to disable automatic updates if preferred.
