  2. Dynamic frequency selection - Wikipedia

    en.wikipedia.org/wiki/Dynamic_frequency_selection

    Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar , satellite communication , and weather radar , and also to provide on aggregate a ...

    en.wikipedia.org/wiki/Channel_allocation_schemes

    In Fixed Channel Allocation or Fixed Channel Assignment (FCA) each cell is given a predetermined set of frequency channels. FCA requires manual frequency planning, which is an arduous task in time-division multiple access (TDMA) and frequency-division multiple access (FDMA) based systems since such systems are highly sensitive to co-channel interference from nearby cells that are reusing the ...

  4. Distributed file system for cloud - Wikipedia

    en.wikipedia.org/wiki/Distributed_file_system...

    Modern data centers must support large, heterogenous environments, consisting of large numbers of computers of varying capacities. Cloud computing coordinates the operation of all such systems, with techniques such as data center networking (DCN), the MapReduce framework, which supports data-intensive computing applications in parallel and distributed systems, and virtualization techniques ...

  5. Data architecture - Wikipedia

    en.wikipedia.org/wiki/Data_architecture

    Data architecture consist of models, policies, rules, and standards that govern which data is collected and how it is stored, arranged, integrated, and put to use in data systems and in organizations. [1] Data is usually one of several architecture domains that form the pillars of an enterprise architecture or solution architecture. [2]

  6. OneFS distributed file system - Wikipedia

    en.wikipedia.org/wiki/OneFS_distributed_file_system

    The OneFS File System is a proprietary file system that can only be managed and controlled by the FreeBSD-derived OneFS Operating System. [3] zsh is the default login shell of the OneFS Operating System. OneFS presents a specialized command set to administer the OneFS File System. [6] Most specialized shell programs start with letters isi.

  7. Comparison of distributed file systems - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_distributed...

    In computing, a distributed file system (DFS) or network file system is any file system that allows access from multiple hosts to files shared via a computer network. This makes it possible for multiple users on multiple machines to share files and storage resources.

  8. Document Content Architecture - Wikipedia

    en.wikipedia.org/wiki/Document_Content_Architecture

    Document Content Architecture, or DCA for short, is a standard developed by IBM for text documents in the early 1980s. DCA was used on mainframe and IBM i systems and formed the basis of DisplayWrite's file format. DCA was later extended as MO:DCA (Mixed Object Document Content Architecture), which added embedded data files.

  9. Distributed Computing Environment - Wikipedia

    DCE/DFS is a DCE-based application which provides a distributed filesystem on DCE. DCE/DFS can support replicas of a fileset (the DCE/DFS equivalent of a filesystem) on multiple DFS servers - there is one read-write copy and zero or more read only copies. Replication is supported between the read-write and the read-only copies.
