    The correct number of sections for a fence is n − 1 if the fence is a free-standing line segment bounded by a post at each of its ends (e.g., a fence between two passageway gaps), n if the fence forms one complete, free-standing loop (e.g., enclosure accessible by surmounting, such as a boxing ring), or n + 1 if posts do not occur at the ends ...

  3. Filesystem in Userspace - Wikipedia

    en.wikipedia.org/wiki/Filesystem_in_Userspace

    The program is also used to mount the new file system. At the time the file system is mounted, the handler is registered with the kernel. If a user now issues read/write/stat requests for this newly mounted file system, the kernel forwards these IO-requests to the handler and then sends the handler's response back to the user. Unmounting a FUSE ...

  4. Fencing (computing) - Wikipedia

    en.wikipedia.org/wiki/Fencing_(computing)

    A node fence (or I/O fence) is a virtual "fence" that separates nodes which must not have access to a shared resource from that resource. It may separate an active node from its backup. If the backup crosses the fence and, for example, tries to control the same disk array as the primary, a data hazard may occur.

  5. Network File System - Wikipedia

    en.wikipedia.org/wiki/Network_File_System

    Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, [1] allowing a user on a client computer to access files over a computer network much like local storage is accessed.

  6. Unix filesystem - Wikipedia

    en.wikipedia.org/wiki/Unix_filesystem

    The filesystem appears as one rooted tree of directories. [1] Instead of addressing separate volumes such as disk partitions, removable media, and network shares as separate trees (as done in DOS and Windows: each drive has a drive letter that denotes the root of its file system tree), such volumes can be mounted on a directory, causing the volume's file system tree to appear as that directory ...

    Succeeded by Hierarchical File System (HFS). Next3 – A form of ext3 with snapshots support. [6] MFS – TiVo's Media File System, a proprietary fault tolerant format used on TiVo hard drives for real time recording from live TV. Minix file system – Used on Minix systems; NILFS – Linux implementation of a log-structured file system

  8. Trust boundary - Wikipedia

    en.wikipedia.org/wiki/Trust_boundary

    Trust boundary is a term used in computer science and security which describes a boundary where program data or execution changes its level of "trust," or where two principals with different capabilities exchange data or commands. The term refers to any distinct boundary where within a system all sub-systems (including data) have equal trust. [1]

  9. InterPlanetary File System - Wikipedia

    en.wikipedia.org/wiki/InterPlanetary_File_System

    The InterPlanetary File System (IPFS) is a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed hash table. By using content addressing , IPFS uniquely identifies each file in a global namespace that connects IPFS hosts , creating a resilient system of file storage and sharing.
