The ability to run across various platforms means that Fuchsia could run not only on smartphones, notebooks, desktops and tablets but also cars, traffic lights, digital televisions, ATMs, airplane controls, point of sale (POS) terminals, digital cameras GPS navigation systems, elevators, digital media receivers and smart meters, among many other possibilities.
The OS is based on the Zircon (formerly Magenta) kernel, which was derived from Little Kernel, a tiny embedded OS. Zircon is a significant departure for Google; Android and Chrome, the company's other two operating systems, are both based on the Linux kernel.
Google Assistant is fully integrated into Fuchsia's context-aware environment. For personal computing, that means the assistant knows about recent activity in the browser and can use that information to guide it in responses. The OS features capacity-based security, which is based on unforgeable tokens of authority connected to objects which have defined access rights.
