The Mach Kernel

The Mach kernel is an advanced core component of an operating system that manages the computer's hardware and software resources. It acts as an intermediary, coordinating tasks like running programs, accessing memory, and communicating with devices such as printers or disk drives. Designed for efficiency and flexibility, Mach allows multiple processes to run simultaneously and securely by controlling their access to hardware. It forms the foundation of systems like NeXTSTEP and early versions of macOS, enabling advanced features like multitasking and hardware abstraction while providing a stable platform for software development.
