Multics was an extremely influential early time-sharing operating system started in 1964 and introduced a large number of new concepts, including dynamic linking and a hierarchical file system. It was extremely powerful, and UNIX can in fact be considered to be a 'simplified' successor to MULTICS (the name 'Unix' is itself a hack on 'Multics'). The last running Multics installation was shut down on October 31, 2000."

In the AIX operating system, software components share the kernel address, creating a serviceability issue for the AIX kernel and kernel extensions.

It is designed exclusively for educational purposes, so the kernel code is kept as simple as possible for the benefit of students. In the latest version, the virtual memory manager code has been improved to support SVGAlib-based applications and to add the ability to mmap() physical addresses. The way to map physical addresses in the /dev/mem driver has been improved. The mmap() and readpage() methods have been added to the VFS structure. Among other improvements in the VFS layer, the code to build with gcc 4.x has been fixed.
