Glossary

As we geek out a bit, it can become confusing with some of the terminologies that are used. So here we go with a helpful glossary.

  • App - An application, especially as downloaded by a user to a mobile device.
  • AWG - American wire gauge - As a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire.
  • CCTV - Closed Circuit TV - Also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.
  • dB - decibel(s) - A unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.
  • Display - An electronic device for the visual presentation of data.
  • DIY - Do It Yourself
  • Frequency - The rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
  • Home Automation - The control of domestic appliances or devices by electronically controlled systems.
  • Hz - Hertz - The frequency equal to one cycle per second.
  • IR - Infrared - In communications and networking, infrared light is used in wired and wireless operations. Remote controls use near-infrared light, transmitted with light-emitting diodes (LEDs), to send focused signals to home-entertainment devices, such as televisions. Infrared light is also used in fiber optic cables to transmit data.
  • LED - A light-emitting diode (a semiconductor diode which glows when a voltage is applied).
  • ohm - The standard unit of electrical resistance in the SI, formally defined to be the electrical resistance between two points of a conductor when a constant potential difference applied between these points produces in this conductor a current of one ampere.
  • RS-232 - A serial interface published by the EIA for asynchronous data communication over distances up to a few hundred feet.
  • SI - International System of Units - an internationally accepted coherent system of physical units, derived from the MKSA (meter-kilogram-second-ampere) system, using the meter, kilogram, second, ampere, Kelvin, mole, and candela as the basic units respectively of the fundamental quantities of length, mass,time, electric current, temperature, amount of substance, and luminous intensity.
  • Smart Home - A home equipped with lighting, heating, and electronic devices that can be controlled remotely by phone or computer.
  • Streaming Service - Is an on-demand online entertainment source for TV shows, movies, and other streaming media.
  • Watt - Corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.
  • Zigbee - Is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, designed for small scale projects which need a wireless connection.
  • Z-Wave - Is a wireless network designed by Zensys Inc. to provide communication between devices in a home control network. Z-Wave may be used to control lights, heating, and air conditioning, and appliances and home security, among other functions.
  • 4K Resolution - A display with a horizontal screen resolution of around 4000 pixels.
  • 8K Resolution - Refers to a display with around 8000 pixels width.
  • 16K Resolution - Refers to a display with around 16000 pixels width.
