    media access management

    In the Open Systems Interconnection (OSI) communication reference model, media access management is performed by the Media Access Control (MAC) sublayer of the Data-Link Layer.

  • media attachment unit (MAU)

    MAU is also sometimes used as the abbreviation for the token ring network multistation access unit (MSAU).

  • Media Gateway Control Protocol (MGCP)

    Media Gateway Control Protocol (MGCP), also known as H.248 and Megaco, is a standard protocol for handling the signaling and session management needed during a multimedia conference.

  • megahertz (MHz)

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

  • Mesh Connectivity Layer (MCL)

    Mesh Connectivity Layer (MCL) is a technology that allows a computer user to connect to a wireless mesh network that uses Wi-Fi or WiMax. The wireless mesh network can be connected to the Internet through a single computer using a leased T-1 line or broadband satellite connection, allowing all network users high-speed Internet access.

  • Metcalfe's Law

    Metcalfe's Law is expressed in two general ways: The number of possible cross-connections in a network grow as the square of the number of computers in the network increases.

  • Metro Ethernet

    Metro Ethernet is the use of Carrier Ethernet technology in metropolitan area networks (MANs)... (Continued)

  • metropolitan area network (MAN)

    A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).

  • MFSK (multiple frequency shift keying)

    MFSK (multiple frequency shift keying), also called multi-frequency shift keying, is a method of signal modulation in which discrete audio tone bursts of various frequencies convey digital data.

  • MHz

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

  • microsegmentation

    Microsegmentation, also known as security segmentation, is a process used by network security professionals to break a network into smaller pieces in order to make it easier to keep the overall system secure.

  • Microsoft Network Access Protection (NAP)

    Network access protection (NAP), introduced with Windows Server 2008, is Microsoft’s approach to controlling access to a network based on a determination of each device’s health.

  • microwave

    The term microwave refers to electromagnetic energy having a frequency higher than 1 gigahertz (billions of cycles per second), corresponding to wavelength shorter than 30 centimeters.

  • mil

    mil is one of the top-level domain names that can be used when choosing a domain name.

  • millimeter wave (MM wave)

    Millimeter wave (also millimeter band) is the band of spectrum between 30 gigahertz (Ghz) and 300 Ghz. Researchers are testing 5G wireless broadband technology on millimeter wave spectrum.
