Kindle Fire

The Kindle Fire is a tablet version of Amazon.com's Kindle e-book reader. Built with Quanta Computer, the Kindle Fire was released in November 2011, featuring a color 7-inch multi-touch display with IPS technology and running a custom version of Google's Android operating system called Fire OS. The Kindle Fire HD followed in September 2012, and the Kindle Fire HDX in September 2013.

History

The device—which includes access to the Amazon Appstore, streaming movies and TV shows, and Kindle's e-books—was released to consumers in the United States on November 15, 2011, after being announced on September 28.

On September 7, 2012, upgrades to the device were announced with consumer availability to those European countries with a localized version of Amazon's website (United Kingdom,France, Germany, Italy and Spain).

The original Kindle Fire retailed for US$199 in 2011. Estimates of the device's initial bill of materials cost ranged from $150 to $202. Amazon's business strategy was stated in 2011 as making money through sales of digital content on the Fire, rather than through sales of the device itself.

Fire HD

Kindle Fire HD, later renamed to Fire HD, are members of the Amazon Kindle Fire family of touchscreen tablet computers. The family consists of: 7", 8.9" (2012 models), 7" (2013 model), 6", 7" (2014 models), 8", 10" (2015 models). The 6", 8", 10" models are currently available.

History

The first model was announced on September 6, 2012 and was available in two models, 7" and 8.9". The 7" model was released in United States on September 14, then France, Germany, Italy, Spain, United Kingdom on October 25 and in Japan on December 18. The 8.9" model was released on November 20 in United States, in Japan on March 12, 2013 in Germany on March 13, and in India on June 27.

On September 25, 2013, the Fire HD second generation was released. The price of the Fire HD 7" was reduced to $139, the processor speed was upgraded to 1.5 GHz, upgraded from "Android based" OS to a compatible proprietary fork of Android named Fire OS 3, removed the front camera, used a new form factor and decreased the available storage options. In addition, the Fire HD's successor the Kindle Fire HDX was introduced.

Fire

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.

Fire is hot because conversion of the weak double bond in molecular oxygen, O₂, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O₂); the bond energies of the fuel play only a minor role here. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.

Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire has been used by humans for cooking, generating heat, light, signaling, and propulsion purposes. The negative effects of fire include hazard to life and property, atmospheric pollution, and water contamination. If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water. Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen caused by a fire produces a long-term reduction in the fertility of the soil, which only slowly recovers as nitrogen is "fixed" from the atmosphere by lightning and by leguminous plants such as clover.

Amazon Kindle

The Amazon Kindle is a series of e-readers designed and marketed by Amazon.com. Amazon Kindle devices enable users to browse, buy, download and read e-books, newspapers, magazines and other digital media via wireless networking to the Kindle Store. The hardware platform, developed by Amazon subsidiary Lab126, began as a single device and now comprises a range of devices, including e-readers with E Ink electronic paper displays, and Android-based tablets with color LCD screens. All Kindle devices integrate with the Kindle Store to get content and as of November 2015, the Kindle Store has over four million e-books available in the US.

Naming and evolution

The Kindle name was devised by branding consultants Michael Cronan and Karin Hibma. Lab 126 tasked them to name the product, so Cronan and Hibma suggested Kindle, meaning to light a fire. They felt this was an apt metaphor for reading and intellectual excitement.

Kindle hardware has evolved from the original Kindle introduced in 2007 and the Kindle DX (with its larger screen) introduced in 2009. The range includes devices with a keyboard (Kindle Keyboard), devices with touch-sensitive high resolution and contrast screens (Kindle Paperwhite), a tablet with the Kindle app (Kindle Fire), and a low-priced model with touch-sensitive screen (Kindle).
