MINIX3.2.1

MINIX 3 is a free, open-source, operating system designed to be highly reliable, flexible, and secure. It is based on a tiny microkernel running in kernel mode with the rest of the operating system running as a collection of isolated, protected, processes in user mode.

MINIX is based on a small microkernel that runs in kernel mode. The rest of the operating system runs as a collection of server processes, each one protected by the hardware MMU. These processes include the virtual file system, one or more actual file systems, the memory manager, the process manager, the reincarnation server, and the device drivers, each one running as a separate user-mode process.

One consequence of this design is that failures of the system due to bugs or attacks are isolated. Few, if any, other operating systems are as self healing as MINIX 3.

Main MINIX 3 Features include:

POSIX compliant with a NetBSD userlandOpen source, with a BSD licenseNetworking with TCP/IPX Window SystemLanguages: C, Perl, Python, etc.Over 650 UNIX programs.
