  • G

    G.703

    G.703 is a CCITT standard for transmitting voice over digital carriers such as T1 and E1. G.703 provides the specifications for pulse code modulation (PCM) at data rates from 64 Kbps to 2.048 Mbps.

  • GARP (Generic Attribute Registration Protocol)

    GARP (Generic Attribute Registration Protocol) is a local area network (LAN) protocol that defines procedures by which end stations and switches can register and de-register attributes, such as network identifiers or addresses, with each other...

  • gigabit

    In data communications, a gigabit is one billion bits, or 1,000,000,000 (that is, 10^9) bits. It's commonly used for measuring the amount of data that is transferred in a second between two telecommunication points.

  • Gigabit Ethernet

    Gigabit Ethernet, a transmission technology based on the Ethernet frame format and protocol used in local area networks (LANs), provides a data rate of 1 billion bits per second (one gigabit). (Continued...)

  • gigahertz (GHz)

    The gigahertz, abbreviated GHz, is a unit of alternating current (AC) or electromagnetic (EM) wave frequency equal to one thousand million hertz (1,000,000,000 Hz).

  • gigapop (gigabit point-of-presence)

    Gigapop is short for gigabit point-of-presence, an access point to Internet2, the network collaboration between universities and partners in industry and government to develop advanced Internet technologies and applications such as telemedicine and digital libraries.

  • GLONASS (Globalnaya Navigatsionnay Sputnikovaya Sistema)

    GLONASS (for Globalnaya Navigatsionnay Sputnikovaya Sistema), the Russian Federation's Global Navigation Satellite System (GNSS), is the Russian version of a global positioning system.

  • GMPLS (Generalized Multiprotocol Label Switching or Multiprotocol Lambda Switching)

    GMPLS (Generalized Multiprotocol Label Switching), also known as Multiprotocol Lambda Switching, is a technology that provides enhancements to Multiprotocol Label Switching (MPLS) to support network switching for time, wavelength, and space switching as well as for packet switching.

  • GNSS (Global Navigation Satellite System)

    GNSS (Global Navigation Satellite System) is a satellite system that is used to pinpoint the geographic location of a user's receiver anywhere in the world.

  • graceful degradation

    Graceful degradation is the ability of a computer, machine, electronic system or network to maintain limited functionality even when a large portion of it has been destroyed or rendered inoperative. The purpose of graceful degradation is to prevent catastrophic failure... (Continued)

  • green networking

    Green networking is the practice of selecting energy-efficient networking technologies and products, and minimizing resource use whenever possible.

  • green route

    A green route is one of three categories of Internet route states defined by the Policy Analysis of Internet Routing (PAIR) project, an initiative dedicated to the development of tools that ISPs (Internet service providers), network operators, and end users can use to troubleshoot Internet routing and policy problems.

  • grey route

    A grey route is one of three categories of Internet routes defined by the Policy Analysis of Internet Routing (PAIR) project, an initiative dedicated to the development of tools that ISPs (Internet service providers), network operators, and end users can use to troubleshoot Internet routing and policy problems.

  • GTAG (Global Tag)

    GTAG (Global Tag) is a standardization initiative of the Uniform Code Council (UCC) and the European Article Numbering Association (EAN) for asset tracking and logistics based on radio frequency identification (RFID).

  • GVRP (GARP VLAN Registration Protocol or Generic VLAN Registration Protocol)

    GVRP (GARP VLAN Registration Protocol or Generic VLAN Registration Protocol) is a protocol that facilitates control of virtual local area networks (VLANs) within a larger network . GVRP conforms to the IEEE 802.1Q specification, which defines a method of tagging frames with VLAN configuration data.
