Unified Kernel

Critical OS components moved into kernel space

Improved system performance

Increased security and robustness

High degree of backwards compatibility

Moving critical drivers, file system, and graphical window manager into the kernel Benefits: Greatly reduces the overhead of system calls between these components Reduces overhead of all calls from user space to kernel space Increase code sharing between base OS services
