F - Definitions

  • F

    Fast Ethernet

    Fast Ethernet is a local area network (LAN) transmission standard that provides a data rate of 100 megabits per second (referred to as "100BASE-T").

  • fast retransmit and recovery (FRR)

    In TCP/IP, fast retransmit and recovery (FRR) is a congestion control algorithm that makes it possible to quickly recover lost data packets.

  • fault management

    Fault management is the component of network management concerned with detecting, isolating and resolving problems.

  • fax

    A fax (short for facsimile and sometimes called telecopying) is the telephonic transmission of scanned-in printed material (text or images), usually to a telephone number associated with a printer or other output device.

  • FCAPS (fault-management, configuration, accounting, performance, and security)

    FCAPS is a network management framework created by the International Organization for Standardization (ISO). FCAPS categorizes the working objectives of network management into five levels. The five levels are:  fault-management (F), the configuration level (C), the accounting level (A), the performance level (P) and the security level (S).

  • Fcc

    In Eudora and perhaps other e-mail facilities, you'll see the abbreviations "Fcc" and "Bcc".

  • FDDI (Fiber Distributed Data Interface)

    FDDI (Fiber Distributed Data Interface) is a set of ANSI and ISO standards for data transmission on fiber optic lines in a local area network (LAN) that can extend in range up to 200 km (124 miles).

  • FECN/BECN (forward explicit congestion notification/backward explicit congestion notification)

    In a frame relay network, FECN (forward explicit congestion notification) is a header bit transmitted by the source (sending) terminal requesting that the destination (receiving) terminal slow down its requests for data.

  • Federation of Telecommunications Engineers of the European Community (FITCE)

    FITCE (Federation of Telecommunications Engineers of the European Community) is an international association that is committed to affecting telecommunication developments in a positive and constructive manner throughout Europe and the rest of the world.

  • femtocell

    A femtocell is a wireless access point that improves cellular reception inside a home or office building. The device, which resembles a wireless router, essentially acts as a VOIP repeater.

  • ferrule

    A ferrule (from Latin viriola, meaning little bracelet) is a ring or cap attached to an object to protect against damage, splitting, or wear.

  • FG-D (Feature Group D)

    FG-D (Feature Group D) is a type of telecommunication trunk used to provide "equal access" capability from telecommunication carriers and central offices (where the switching equipment is located and customer lines are connected and terminated) to the access tandem.

  • fiber jumper

    A fiber jumper, sometimes called a fiber patch cord is a length of fiber cabling fitted with LC, SC, MTRJ or ST connectors at each end... (Continued)

  • fiber optic

    Fiber optic (or "optical fiber") refers to the medium and the technology associated with the transmission of information as light impulses along a glass or plastic wire or fiber.

  • fiber optics (optical fiber)

    Fiber optics, or optical fiber, refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber.
