8. 2 GB of Virtual Memory per process 32,000 processes Unified Kernel Critical OS components moved into kernel space Improved system performance Increased security and robustness High degree of backwards compatibility

9. 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

10. App makes call Kernel Validates parameters Maps service into slot 0 Calls into the service Service Runs Returns to the Kernel Kernel Maps App into slot 0 Returns to App Kernel Application Service (FileSys) (Device) (GWES)

11. App makes call Same call to coredll.dll App stays mapped during the call Kernel Validates parameters Calls into the service Service Runs Returns directly to the App Kernel Application Service
