- OS: Project is an Operating System Kernel ×
An OS Kernel, with native support of network applications.
Exploring the possibilities of doing an Operating System completely different than all of the existing ones. Instead of basing it upon concepts that are 40 years old, design it from the ground up object oriented, peer-to-peer, and for security.1 weekly downloads
NotOS is multitasking, multithreading simple operating system based on monolithic kernel. NotOS haves paging-based memory management and software-based task switching. It works on Intel Pentium processor and others, based on Pentium.
