British Thermal Unit (BTU) is the measurement for a unit of energy equivalent to the amount needed to heat one pound of water by 1 degree Fahrenheit. A BTU is used as the standard measurement unit to express how much energy a fuel has and to quantify how much output any device that generates heat can produce. For example, dry wood is considered to have approximately 7,000 BTUs per pound. Other heat producing devices such as gas grills are measured by the total capacity of BTUs that can be produced Read More

Universal Serial Bus is an external bus that is used to connect a number of peripherals to computers, cell phones and other gadgets. A Micro-USB is very small in size when compared to the size of the Mini-USB and the old USB. In addition to the small size, a Micro-USB is more durable than a Mini-USB as it features a stainless-steel shell. The stainless-steel shell used in the Micro-USB allows over 10,000 insertion cycles. For lighter PDAs and cell phones, the small size of the Micro-USB makes it a better Read More

RGB stands for the three primary colors of light – Red, Green, and Blue. RGB can be described as the computer’s native color space for capturing images and displaying them. As human eyes are sensitive to these primary colors – red, green, and blue – all colors are perceived as a combination of these three colors. The RGB color model, based on a Cartesian coordinate system, is considered as an addictive model in which red, green, and blue, are combined in several methods to reproduce all other colors. In the Read More

Electromagnetic Interference (EMI) most commonly occurs in the 104 to 1012 Hertz frequency range of the electromagnetic spectrum. A number of sources create this interference, including radio transmitters, electric motors, power lines, fluorescent lights, and computer circuits. If electrical equipment do not have suitable EMI shielding in place, device failure may result from the interference due to the number of sensitive electronic components in most electronic equipment produced today. Although there are many national regulations that restrict products emissions today, taking into account EMI shielding for organically and non-organically created Read More
