Unix architecture

A Unix architecture is a computer operating system system architecture that embodies the Unix philosophy. It may adhere to standards such as the Single UNIX Specification (SUS) or similar POSIX IEEE standard. No single published standard describes all Unix architecture computer operating systems - this is in part a legacy of the Unix wars.

Notable among these are the GNU/Linux distributions. The distinctions between Unix and Unix-like systems have been the subject of heated legal battles, and the holders of the UNIX brand, The Open Group, object to 'Unix-like' and similar terms. For distinctions between SUS branded UNIX architectures and other similar architectures, see Unix-like. A Unix kernel — the core or key components of the operating system — consists of many kernel subsystems like process management, scheduling, file management, device management and network management, memory management, dealing with interrupts from hardware devices.
