Background：There is no software implementation which satisfies various requirements of whole systems to the kernel functionalities.
Purpose：

Contribute to develop democratized systems by rethinking the current ossified operating system software and the Internet.
Contribution by solving real problems in the world, not research for research.

Library Operating System

Operating system (OS) is at the heart of information technology systems and has been improved its ability and performance as the advance of underlying technology with various contributions. The purpose of OS is being brain of computers, in which various resources are consumed by various components. The brain behaves based on various policies with different objectives of services running on computers. Although research and development of OS has a long history and OS and its implementation of kernel, which is a core part of OS, is already a matured technology, there are still issues with the current usage of OS in newly introduced use cases. Our motivation in library operating system project is to offer a matured operating system in the different environment by not using machine virtualization in order to be more agile and flexible software library.
