Hardware Definitions

  • M

    machine data

    Machine data is digital information created by the activity of computers, mobile phones, embedded systems and other networked devices.

  • machine-to-machine (M2M)

    Machine-to-machine, or M2M, is a broad label that can be used to describe any technology that enables networked devices to exchange information and perform actions without the manual assistance of humans.

  • MEMS (micro-electromechanical systems)

    A MEMS (micro-electromechanical system) is a miniature machine that has both mechanical and electronic components.

  • microcomputer

    A microcomputer is a complete computer on a smaller scale and is generally a synonym for the more common term, personal computer or PC, a computer designed for an individual.

  • microcontroller

    A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system.

  • mobile robot (mobile robotics)

    A mobile robot is a machine controlled by software that use sensors and other technology to identify its surroundings and move around its environment.

  • P

    passive sensor

    Passive sensor technologies gather target data through the detection of vibrations, light, radiation, heat or other phenomena occurring in the subject’s environment.  They contrast with active sensors, which include transmitters that send out a signal, a light wavelength or electrons to be bounced off the target, with data gathered by the sensor upon their reflection.

  • pervasive computing (ubiquitous computing)

    Pervasive computing, also called ubiquitous computing, is the growing trend of embedding computational capability (generally in the form of microprocessors) into everyday objects to make them effectively communicate and perform useful tasks in a way that minimizes the end user's need to interact with computers as computers.

  • R

    RFID (radio frequency identification)

    RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person.

  • RFID tagging

    RFID tagging uses small radio frequency identification devices to track and identify objects.

  • S

    smart bulb (smart light bulb)

    A smart bulb is a networked LED light bulb that has additional features to enable automation, presence-sensing capabilities and customization.

  • smart grid sensor

    A smart grid sensor is a small, lightweight node that serves as a detection station in a sensor network.

  • smart home hub (home automation hub)

    A smart home hub is hardware or software that connects devices on a home automation network and controls communications among them.

  • smart meter

    A smart meter is an Internet-capable device that measures energy, water or natural gas consumption of a building or home.

  • smartwatch

    A smartwatch is a wearable computing device that closely resembles a wristwatch or other time-keeping device.
