BlackBerry (company)
BlackBerry Limited, formerly Research In Motion (RIM), is a Canadian software company specializing in secure communications and the Internet of Things (IoT). Founded in 1984, it developed the BlackBerry brand of interactive pagers, smartphones, and tablets. The company transitioned to providing software and services and holds critical software application patents. Initially leading the mobile phone and pager industry in the 1980s and 90s, the company struggled to gain a lasting presence in the smartphone market of the new millennium. BlackBerry led the market in many countries, particularly the United States, until 2010, with the announcement of the iPhone 4. The company withered against the rapid rise of Apple and Android. After the troubled launch of the BlackBerry 10, it transitioned to a cybersecurity enterprise software and services company under CEO John S. Chen. In 2018, the last BlackBerry smartphone, the BlackBerry Key2 LE, was released. In 2022, BlackBerry discon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enhanced Data Rates For GSM Evolution
Enhanced Data rates for GSM Evolution (EDGE), also known as 2.75G and under various other names, is a 2G digital mobile phone technology for packet switched data transmission. It is a subset of General Packet Radio Service (GPRS) on the GSM network and improves upon it offering speeds close to 3G technology, hence the name 2.75G. EDGE is standardized by the 3GPP as part of the GSM family and as an upgrade to GPRS. EDGE was deployed on GSM networks beginning in 2003 – initially by Cingular (now AT&T) in the United States. It could be readily deployed on existing GSM and GPRS cellular equipment, making it an easier upgrade for cellular companies compared to the UMTS 3G technology that required significant changes. Through the introduction of sophisticated methods of coding and transmitting data, EDGE delivers higher bit-rates per radio channel, resulting in a threefold increase in capacity and performance compared with an ordinary GSM/GPRS connection - originally a max ...

Luxury Goods
In economics, a luxury good (or upmarket good) is a good (economics), good for which demand (economics), demand increases more than what is proportional as income rises, so that expenditures on the good become a more significant proportion of overall spending. Luxury goods are in contrast to necessity goods, where demand increases proportionally less than income. ''Luxury goods'' is often used synonymously with superior goods. Definition and etymology The word "luxury" derives from the Latin verb ''luxor'' meaning to overextend or strain. From this, the noun ''luxuria'' and verb ''luxurio'' developed, "indicating immoderate growth, swelling, ... in persons and animals, willful or unruly behavior, disregard for moral restraints, and licensciousness", and the term has had negative connotations for most of its long history. One definition in the OED is a "thing desirable but not necessary". A luxury good can be identified by comparing the demand for the good at one point in time agai ...

HDMI
High-Definition Multimedia Interface (HDMI) is a proprietary digital interface used to transmit high-quality video and audio signals between devices. It is commonly used to connect devices such as televisions, computer monitors, projectors, gaming consoles, and personal computers. HDMI supports uncompressed video and either compressed or uncompressed digital audio, allowing a single cable to carry both signals. Introduced in 2003, HDMI largely replaced older analog video standards such as composite video, S-Video, and VGA connector, VGA in consumer electronics. It was developed based on the CEA-861 standard, which was also used with the earlier Digital Visual Interface (DVI). HDMI is electrically compatible with DVI video signals, and adapters allow interoperability between the two without signal conversion or loss of quality. Adapters and active converters are also available for connecting HDMI to other video interfaces, including the older analog formats, as well as digital fo ...

Near Field Communication
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band, compliant with the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 848 kbit/s. The NFC Forum has helped define and promote the technology, setting standards for certifying device compliance. Secure communications are available by applying encryption algorithms as is done for credit cards and if they fit the criteria for being considered a personal area network. NFC ...

Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs Ultra high frequency, UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones, wireless speakers, HIFI systems, car audio and wireless transmission between TVs and soundbars. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The Institute of Electrical and Electronics Engineers, IEEE standardized Bluetooth as IEEE 802.15.1 but no longer maintains ...

IEEE 802
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active. The IEEE 802 standards are restricted to computer networks carrying variable-size packets, unlike cell relay networks, for example, in which data is transmitted in short, uniformly sized units called cells. Isochronous signal networks, in which data is transmitted as a steady stream of octet (computing), octets, or groups of octets, at regular time intervals, are also outside the scope of the IEEE 802 standards. The number 802 has no significance: it was simply the next number in the sequence that the IEEE used fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
720p
720p (720 lines progressive) is a progressive HD signal format with 720 horizontal lines/1280 columns and an aspect ratio (AR) of 16:9, normally known as widescreen HD (1.78:1). All major HD broadcasting standards (such as SMPTE 292M) include a 720p format, which has a resolution of 1280×720. The number ''720'' stands for the 720 horizontal scan lines of image display resolution (also known as 720 pixels of vertical resolution). The ''p'' stands for progressive scan, i.e. non-interlaced. When broadcast at 60 frames per second, 720p features the highest temporal resolution possible under the ATSC and DVB standards. The term assumes a widescreen aspect ratio of 16:9, thus implying a resolution of 1280×720 px (0.9 megapixels). 720i (720 lines interlaced) is an erroneous term found in numerous sources and publications. Typically, it is a typographical error in which the author is referring to the 720p HDTV format. However, in some cases it is incorrectly presented ...

1080p
1080p (1920 × 1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the ''p'' stands for progressive scan, ''i.e.'' non- interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes referred to as 2K resolution (meaning having a horizontal resolution of approximately 2,000 pixels), other sources differentiate between 1080p and (true) 2K resolution. 1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movi ...

Megapixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a Raster graphics, raster image, or the smallest addressable element in a dot matrix display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a Sampling (signal processing), sample of an original image; more samples typically provide more accurate representations of the original. The Intensity (physics), intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as RGB color model, red, green, and blue, or CMYK color model, cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''wikt:sensel, sensel'' is sometimes used), while in yet ...

BlackBerry Z10
The BlackBerry Z10 was an LTE touchscreen-based smartphone developed by BlackBerry, previously known as RIM. The BlackBerry Z10 was the first of two new BlackBerry phones presented at the BlackBerry 10 event on January 30, 2013. The BlackBerry Z10 was followed by the Z30. Development BlackBerry's chief operating officer Kristian Tear and chief marketing officer Frank Boulben fought against co-founder and former co-CEO Mike Lazaridis to have the touchscreen Z10 prioritized over the Q10 which had a physical keyboard. Boublen was then responsible for and received "criticism for the marketing campaign that supported the Z10 launch, including a confusing Super Bowl advertisement which some board members hated". Both Tear and Boublen were ousted on November 25, 2013 by new CEO John S. Chen, whom weeks earlier had replaced Thorsten Heins. Software The BlackBerry Z10 used the BlackBerry 10 (at the time running on 10.3.3) mobile operating system based on QNX. The user interfa ...
