Radeon HD 6000 Series
The Northern Islands series is a family of GPUs developed by Advanced Micro Devices (AMD) forming part of its Radeon-brand, based on the 40 nm process. Some models are based on TeraScale 2 (VLIW5), some on the new TeraScale 3 (VLIW4) introduced with them. Starting with this family, the former ATI brand was officially discontinued in favor of making a correlation between the graphics products and the AMD branding for computing platforms (the CPUs and chipsets). Therefore, the AMD brand was used as the replacement. The logo for graphics products and technologies also received a minor makeover (using design elements of the 2010 "AMD Vision" logo). Its direct competitor was Nvidia's GeForce 500 Series; they were launched approximately a month apart.

Toothing
Toothing was originally a hoax claim that Bluetooth-enabled mobile phones or PDAs were being used to arrange random sexual encounters, perpetrated as a prank on the media who reported it. The hoax was created by Ste Curran, then Editor at Large at the gaming magazine Edge, and ex-journalist Simon Byron. They based it on the two concepts dogging and bluejacking that were popular at the time. The creators started a forum in March 2004 where they wrote fake news articles about toothing with other members and then sent them off to well-known Internet-based news services. The point of the hoax was to "highlight how journalists are happy to believe something is true without necessarily checking the facts". Dozens of news organizations, including BBC News, Wired News, and The Independent thought the toothing story was real and printed it. On April 4, 2005, Curran and Byron admitted that the whole thing was a hoax. There have, however, been real Bluetooth dating devices since.

Precision Agriculture and Sensor Systems Applications in Colombia
The growing global demand for food and the environmental impact caused by agriculture have made this activity increasingly dependent on electronics, information technology, and telecommunications technologies. In Colombia, agriculture is of great importance not only as a commercial activity, but also as a source of food and employment. However, the concept of smart agriculture has not been widely applied in this country, resulting in the high production of various types of crops due to the planting of large areas of land, rather than optimization of the processes involved in the activity. Due to its technical characteristics and the radio spectrum considered in its deployment, 5G can be seen as one of the technologies that could generate the greatest benefits for the Colombian agricultural sector, especially in the most remote rural areas, which currently lack mobile network coverage.

Environmental Audio Extensions
The Environmental Audio Extensions (or EAX) are a number of digital signal processing presets for audio, present in Creative Technology Sound Blaster sound cards starting with the Sound Blaster Live and the Creative NOMAD/Creative ZEN product lines. Due to the release of Windows Vista in 2007, which deprecated the DirectSound3D API that EAX was based on, Creative discouraged EAX implementation in favour of its OpenAL-based EFX equivalent – though at that point relatively few games used the API.

WiMAX
Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options. The WiMAX Forum was formed in June 2001 to promote conformity and interoperability, including the definition of system profiles for commercial vendors. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL". IEEE 802.16m or WirelessMAN-Advanced was a candidate for 4G, in competition with the LTE Advanced standard. WiMAX was initially designed to provide 30 to 40 megabit-per-second data rates, with the 2011 update providing up to 1 Gbit/s for fixed stations. WiMAX release 2.1, popularly branded as WiMAX 2+, is a backwards-compatible transition from previous WiMAX generations. It is compatible and interoperable with TD-LTE.

Ultra-Dense Networks Taxonomy
Ultra-Dense Network (UDN) is a network with a spatial density of access points (APs) (or base stations) identical to or larger than the number of active end devices—EDs (user equipments (UEs) or physical devices (PDs)). UDNs can be seen as a network paradigm which can be implemented in the context of various kinds of wireless networks, such as sensor/IoT (Internet of Things) networks, mobile networks, aerial networks, and even satellite networks.

Opening Credits
In a motion picture, television program or video game, the opening credits or opening titles are shown at the very beginning and list the most important members of the production. They are now usually shown as text superimposed on a blank screen or static pictures, or sometimes on top of action in the show. There may or may not be accompanying music. When opening credits are built into a separate sequence of their own, the correct term is a title sequence (such as the familiar James Bond and Pink Panther title sequences). Opening credits since the early 1980s, if present at all, identify the major actors and crew, while the closing credits list an extensive cast and production crew. Historically, however, opening credits have been the only source of crew credits and, largely, the cast, although over time the tendency to repeat the cast, and perhaps add a few players, with their roles identified (as was not always the case in the opening credits), evolved. The ascendancy of television movies after 1964 and the increasingly short "shelf-life" of films in theaters has largely contributed to the credits convention which came with television programs from the beginning, of holding the vast majority of cast and crew information for display at the end of the show. In movies and television, the title and opening credits may be preceded by a "cold open," or teaser (in other words, a brief scene prior to the main acts), that helps to set the stage for the episode or film.

ATI Video Card Suffixes
ATI video cards can have one of multiple suffixes attached to their name indicating relative level of performance, the use of suffixes was abandoned with the release of Radeon HD 3000 series products, the last two digits of the model number was then used to indicate relative performance of the products, except for the "X2" suffix indicating dual-GPU solutions, such that the product has two GPUs on one PCB. Below is the listing of the suffixes used in previous generations of products, in order from least powerful (at the top) to the most powerful. (at the bottom) Not all suffixes will be found on a particular line of cards.

Stunting (Broadcasting)
In radio broadcasting, stunting occurs when a station abruptly airs content that is seemingly uncharacteristic compared to what they normally play. The tactic is commonly used when a station is about to undergo a major change (such as a change in format, branding, frequency, ownership or management, or even the acquisition of a high-profile program or personality), or simply as a prank on listeners and rival broadcasters. Either way, stunting is intended as a way to generate a greater amount of media publicity and audience attention to the station, by virtue of its shock value, than a straightforward format change could provide. Depending on the station's situation and its management's preference, stunt formats can last anywhere from a few minutes to several weeks before the permanent change is launched.

PXL-2000
The PXL-2000 (also known as Fisher-Price PXL2000, Fisher-Price PixelVision, Sanwa Sanpix1000, KiddieCorder, and Georgia) is a toy black-and-white camcorder produced in 1987 that uses a compact audio cassette as its recording medium. The PXL-2000 was created by a team of inventors led by James Wickstead, who sold the rights to Fisher-Price in 1987 at the American International Toy Fair in Manhattan. Surviving on the market for merely a year, only around 400,000 units were ever produced, resulting in the PXL-2000's eventual present status as a sought-after cult object among many artists and media historians.
