Plan 9 is a distributed operating system, designed to make a network of heterogeneous and geographically separated computers function as a single system. In a typical Plan 9 installation, users work at terminals running the window system rio , and they access CPU servers which handle computation-intensive processes.
Unix ( / ˈjuːnɪks / ⓘ, YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 [1] at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
Remzi Arpaci-Dusseau is a professor at the University of Wisconsin-Madison and former chair of the Computer Sciences department. [1] He co-leads a research group with Professor Andrea Arpaci-Dusseau. [2] He and Andrea have co-written a textbook on operating systems, "Operating Systems: Three Easy Pieces" (OSTEP), that is downloaded millions of ...
A Linux-based system is a modular Unix-like operating system, deriving much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, the Linux kernel, which handles process control, networking, access to the peripherals, and file systems.
Business Operating System (BOS) – developed to be ported across microcomputers. EOS – developed by ETA Systems for use in their ETA-10 line of supercomputers. EMBOS – developed by Elxsi for use on their mini-supercomputers. GCOS – a proprietary operating system originally developed by General Electric.
Distributed lock manager. Operating systems use lock managers to organise and serialise the access to resources. A distributed lock manager (DLM) runs in every machine in a cluster, with an identical copy of a cluster-wide lock database. In this way a DLM provides software applications which are distributed across a cluster on multiple machines ...
Sprite is an experimental Unix-like distributed operating system developed at the University of California, Berkeley by John Ousterhout 's research group between 1984 and 1992. Its notable features include support for single system image on computer clusters [1] and the introduction of the log-structured filesystem.
HarmonyOS. HarmonyOS ( HMOS) ( Chinese: 鸿蒙; pinyin: Hóngméng) is a distributed operating system developed by Huawei for smartphones, tablets, smart TVs, smart watches, personal computers and other smart devices. It has a single real-time microkernel design in kernel mode with a single framework: the operating system derives from HarmonyOS ...
