GNU Hurd

GNU Hurd is an operating system kernel that serves as the core software managing computer hardware and software resources. Unlike traditional systems like Windows or macOS, Hurd is designed to be flexible and modular, allowing different components to be added or modified independently. It aims to create a free, open-source system that provides users with greater control and customization. Built on the GNU project, Hurd emphasizes security, stability, and freedom, but it is still in development and not as widely used as other operating systems.
