    Manchester encoding

    In data transmission, Manchester encoding is a form of digital encoding in which a data bit's state -- 0 or 1 -- is represented by the transition from one voltage level to another.

  • maximum transmission unit (MTU)

    The maximum transmission unit (MTU) is the largest size frame or packet -- in bytes or octets (eight-bit bytes) -- that can be transmitted across a data link.

  • MDI/MDIX (medium-dependent interface/MDI crossover)

    MDI/MDIX is a type of Ethernet port connection that uses twisted-pair cabling to link two networked devices.

  • mean time to innocence

    Mean time to innocence is the average elapsed time between when a system problem is detected and any given team's ability to say the team or part of its system is not the root cause of the problem.

  • megabits per second (Mbps)

    Megabits per second (Mbps) are units of measurement for network bandwidth and throughput. It is used to show how fast a network or internet connection is.

  • megahertz (MHz)

    Megahertz (MHz) is a unit multiplier that represents one million hertz (106 Hz). Hertz is the standard unit of frequency in the International System of Units (SI).

  • metropolitan area network (MAN)

    A metropolitan area network (MAN) is a computer network that is larger than a single building local area network (LAN) but is located in a single geographic area that is smaller than a wide area network (WAN).

  • microsegmentation

    Microsegmentation is a security technique that splits a network into definable zones and uses policies to dictate how data and applications within those zones can be accessed and controlled.

  • millimeter wave (mmWave)

    Millimeter wave (mmWave), also known as millimeter band, is a range of electromagnetic frequencies between microwaves and infrared.

  • multi-user MIMO

    Multi-user MIMO, or MU-MIMO, is a wireless communication technology that uses multiple antennas to improve communication by creating multiple connections to the same device at the same time.

  • Multiprotocol Label Switching (MPLS)

    Multiprotocol Label Switching (MPLS) is a switching mechanism used in wide area networks (WANs).

  • mutual exclusion (mutex)

    In computer programming, a mutual exclusion (mutex) is a program object that prevents multiple threads from accessing the same shared resource simultaneously.

  • What are managed network services?

    Managed network services are networking applications, functions and services that a managed service provider (MSP) remotely operates, monitors and maintains for an enterprise.

  • What is a MAC address and how do I find it?

    A MAC address (media access control address) is a 12-digit hexadecimal number assigned to each device connected to the network.

  • What is modulation?

    Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal.

  • What is multiplexing and how does it work?

    Multiplexing, or 'muxing,' is a way of sending multiple signals or streams of information over a communications link at the same time in the form of a single, complex signal.
