W - Definitions

  • W

    Wake on LAN

    Wake on LAN is a technology that allows a network professional to remotely power on a computer or to wake it up from sleep mode.

  • WAN (wide area network)

    A wide area network (WAN) is a geographically distributed telecommunications network that interconnects multiple local area networks (LANs).

  • WAN accelerator

    A WAN accelerator is an appliance that improves the end user's experience on a wide area network (WAN).

  • WAN clustering (geoclustering, high-availability clustering or remote clustering)

    WAN clustering, also called geoclustering, high-availability clustering or remote clustering, is the use of multiple redundant computing resources located in different geographical locations to form what appears to be a single highly-available system.

  • WAN interface card (WIC)

    A WAN interface card, or WIC, is a specialized network interface card (NIC) that allows devices to connect to a wide area network.

  • WAN optimization (WAN acceleration)

    WAN optimization, also known as WAN acceleration, is the category of technologies and techniques used to maximize the efficiency of data flow across a wide area network (WAN).

  • WATS (wide-area telephone service)

    WATS (wide-area telephone service) is a specialized form of fixed-rate long-distance telecommunication service.

  • wavelength

    A wavelength is a measure of distance between two identical peaks or crests -- high points -- or between two identical troughs -- low points -- in a wave.

  • wavelength-division multiplexing (WDM)

    Wavelength-division multiplexing (WDM) is a method of combining multiple signals on laser beams at various infared (IR) wavelengths for transmission along fiber optic media. Each laser is modulated by an independent set of signals. Wavelength-sensitive filters, the IR analog of visible-light color filters, are used at the receiving end... (Continued...)

  • Webcast

    Also see push technology, another usage.

  • WebNFS

    WebNFS is a product and proposed standard protocol from Sun Microsystems that extends its Network File System (NFS) to the Internet.

  • weighted fair queueing (WFQ)

    Weighted fair queueing (WFQ) is a method of automatically smoothing out the flow of data in packet-switched communication networks by sorting packets to minimize the average latency and prevent exaggerated discrepancies between the transmission efficiency afforded to narrowband versus broadband signals.

  • well-known port numbers

    The well-known port numbers are the port numbers that are reserved for assignment by the Internet Corporation for Assigned Names and Numbers (ICANN) for use by the application end points that communicate using the Internet's Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP).

  • white box switch

    A white box switch is built on a low-cost, bare metal device that runs on merchant silicon.

  • whiteboard

    A whiteboard is a non-electronic variation of the traditional "rewriteable" schoolroom blackboard, but is white instead of black and of a material that can be written on with colored markers (known as dry erase markers).
