Plan 9 from Bell Labs is a distributed operating system which originated from the Computing Science Research Center (CSRC) at Bell Labs in the mid-1980s and built on UNIX concepts first developed there in the late 1960s. Since 2000, Plan 9 has been free and open-source. The final official release was in early 2015.
Distributed operating system. A distributed operating system is system software over a collection of independent software, networked, communicating, and physically separate computational nodes. They handle jobs which are serviced by multiple CPUs. [1] Each individual node holds a specific software subset of the global aggregate operating system.
Middleware in the context of distributed applications is software that provides services beyond those provided by the operating system to enable the various components of a distributed system to communicate and manage data. Middleware supports and simplifies complex distributed applications. It includes web servers, application servers ...
HarmonyOS is designed with a layered architecture, which consists of four layers; the kernel layer at the bottom provides the upper three layers, i.e., the system service layer, framework layer and application layer, with basic kernel capabilities, such as process and thread management, memory management, file system, network management, and peripheral management.
Distributed computing. Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. [1][2] The components of a distributed system communicate and coordinate their actions by passing messages to one another in ...
ChorusOS is a microkernel real-time operating system designed as a message passing computing model. ChorusOS began as the Chorus distributed real-time operating system research project at the French Institute for Research in Computer Science and Automation (INRIA) in 1979. [1] During the 1980s, Chorus was one of two earliest microkernels (the ...
Edge computing. Edge computing is a distributed computing model that brings computation and data storage closer to the sources of data. More broadly, it refers to any design that pushes computation physically closer to a user, so as to reduce the latency compared to when an application runs on a centralized data centre. [1]
The article " Usage share of operating systems " provides a broader, and more general, comparison of operating systems that includes servers, mainframes and supercomputers. Because of the large number and variety of available Linux distributions, they are all grouped under a single entry; see comparison of Linux distributions for a detailed ...
